Description

The present invention relates to a design support device, a design support system, a design support method, and a design support program.

In designing a building, by using CAD (Computer Aided Design) that realizes BIM (Building Information Modeling), CAD drawings such as three-dimensional drawings and two-dimensional drawings that realize BIM of buildings are created. BIM for buildings is composed of various objects, including the structural framework such as beams, columns, and floor slabs that make up the building, as well as piping, various types of equipment, etc., and each object contains information about the shape in three-dimensional space and , various attribute information such as information regarding materials, dimensions, installation positions, etc. are linked. By using CAD drawings that realize BIM, the life cycle of a building, from various design stages such as architectural design, structural design, and equipment design, to the implementation stage, and even the post-construction maintenance stage, can be improved. It is possible to utilize the information accumulated in each object that makes up the building, making it possible to perform tasks efficiently each time.

For example, a base model, which is a three-dimensional model of a building, is generated, and multiple functions such as architectural designers, structural designers, facility designers, and quantity surveyors refer to the information obtained from the base model. An architectural design and construction planning method has been proposed in which a functional model is generated as a three-dimensional model, and attribute information for each element of the building is added to the base model based on information regarding the requirements of the building owner. For example, see Patent Document 1).

When creating CAD drawings of buildings using conventional BIM, the presence or absence of interference between existing objects is checked, and if interference occurs, the placement position of one object may be changed or By providing a through hole, measures are taken such as allowing the other object to pass through the through hole to avoid interference.

By the way, there are basic seismic isolation buildings in which seismic isolation devices are installed in the building's foundation, intermediate-level seismic isolation buildings in which seismic isolation devices are installed in the middle layer of the building, and building structures and roofs. In various types of base-isolated buildings such as roof base-isolated buildings that have base isolation devices installed between them, when the base isolation devices operate during an earthquake, the period of ground shaking differs from the period of shaking of the building. , seismic energy can be absorbed by seismic isolation devices. Since the seismic isolation device operates in this way, it exists independently from the seismic isolation device within the operating range of the seismic isolation device (relative displacement occurs between the seismic isolation device and the seismic isolation device when the seismic isolation device is displaced). If an object is present, interference may occur between the object and the displacing seismic isolation device.

Further, one aspect of the design support system according to the present invention is
a plurality of user terminals including the design support device and a communication device;

For example, technical study data D14, construction plan data D15, construction management data D16, etc. are generated based on the BIM model and the like. As shown in FIG. 5, based on the cost data D09, for example, an estimation process PS01, a cost management process PS02, a budget management process PS03, etc. are executed. By executing these processes, the design support device 50 can create documents such as a design document FL1, a bill FL2, or an estimate FL3, for example. Specifically, based on the estimate process PS01, the amount and the like written on the bill FL2, estimate FL3, etc. can be calculated.

The cost management process PS02 calculates the amounts used for cost management such as variable costs and fixed costs, and calculates the amounts written in documents such as the design document FL1.

The budget management process PS03 calculates the amount of money used to manage the budget. For example, expected costs used when creating a budget, progress levels used for management based on construction progress criteria, etc. are calculated. In this way, the budget management process PS03 can calculate the amount and the like to be written in the estimate FL3.

Using the technical study data D14, for example, processes such as heat/air flow simulation PS04, static pressure calculation, lift calculation PS05, etc. are executed. Further, based on the technical study data D14, processing such as a placement simulation PS06 of a frame, steel materials, hanging/anchors, etc. is executed. Further, based on the technical study data D14, a sound simulation PS07 such as noise, silencing, and sound insulation is executed.

For example, FIG. 10 is a diagram showing an example of construction plan data.

As illustrated, the construction plan data D15 is, for example, data in the form of a so-called Gantt chart, etc., indicating a schedule, etc., and is data indicating a work schedule in the construction of a building. Using the construction plan data D15, processes such as a process plan drafting PS09 for formulating a process plan are executed based on the schedule of each process indicated by the construction plan data D15.

Similarly, plans for safety in each process, plans for personnel in each process, plans for construction methods in each process, plans for bringing in equipment, plans for test runs, etc. It is created through processes such as PS11, construction method planning PS12, delivery planning PS13, and test run planning PS14.

The construction management data D16 is data used for various management in construction of a building. For example, at a construction site, progress, actual items, cost, etc. are managed. Among these, the construction management data D16 is used, for example, when managing progress and actual items. Specifically, processes such as progress management PS15, order/delivery management PS16, inspection/record management PS17, etc. are executed using the construction management data D16. For example, management tables, records, etc. are created through processes such as the progress management PS 15, the order/delivery management PS 16, and the inspection/record management PS 17.

The change data D17 is data generated by performing an operation to change materials and equipment installed in a building on VR (Virtual Reality) displayed based on the CAD data D13 and the like. Specifically, when a building is designed and the design details are input into the CAD data D13, etc., the arrangement of materials and equipment in the building is also input into the CAD data D13. By displaying the CAD data D13 in VR, for example, it is possible to virtually display the completed building. Therefore, the user can view the completed building, the arrangement of materials and equipment in the building, etc. in the virtual space even at the design stage. In this way, by using the VR display to show the expected completion of the building, for example, conflicts between the client and the designer of the building can be eliminated. Furthermore, if the facility design user or the like differs from his or her own intention in the arrangement of materials and equipment, he or she can perform an operation to change the arrangement of materials and equipment by viewing the VR display displayed in the VR display processing PS19.

In this way, when an operation to change the arrangement of materials and equipment is input by the change operation reception processing PS18, the operation contents, that is, the changes that indicate the equipment and materials whose arrangement is to be changed and the position of the materials and equipment after the change, etc. Data D17 is generated. Then, the CAD data D13 and the like are changed based on the change data D17. In addition, "table output" or the like may be performed in which each piece of information is displayed in a table format or the like. Furthermore, by converting the CAD data D13, etc., "2D drawing output" or the like may be performed to display a design drawing or the like as a 2D drawing. In addition, "information sharing with the field etc." may be performed by transmitting and receiving each information to a mobile terminal or the like. Furthermore, "production information input/output" for transmitting/receiving various information used in the construction of a building may be performed.

Returning to FIG. 4, the design support device 50 stores the above-mentioned various data in the storage unit 560. Attribute information shown as an example in FIG. 9 regarding a seismically isolated building, which is mainly designed by the design support device 50, is stored.

The BIM model created in the processing section 530 is stored in the storage section 560 and displayed on the display section 550. The display unit 550 has a function of displaying an operation screen for the user based on commands from the CPU 502, and is formed of a liquid crystal display (LCD) or the like.

The determination unit 540 determines whether there is interference between the operating range of the seismic isolation device and other objects. For example, for a BIM model of a seismically isolated building created by a structural design user, a facility design user installs various piping and equipment (equivalent to other objects) in the seismic isolation layer where a seismic isolation device is installed. In doing so, the determination unit 540 determines whether there is interference between other objects and the operating range of the seismic isolation device.

If the determination unit 540 determines that another object and the operating range of the seismic isolation device interfere, an error is displayed on the display unit 550. This error display includes a lighting display, a capital letter display, an alarm sound display such as a buzzer, and a combination thereof.

If an error is displayed on the display unit 550, the facility design user changes the placement position of other objects and reviews the installation position so that the other objects do not interfere with the operating range of the seismic isolation device.

[Design support method according to first embodiment]
Next, an example of the design support method according to the first embodiment will be described with reference to FIGS. 11 and 12. Here, FIG. 11 is a flowchart showing an example of the design support method according to the first embodiment, and FIG. 12 is a side view showing an example of a seismic isolation layer between the base frame and the overlying frame.

At the start of the design support method according to the embodiment, a structural design user performs structural calculations regarding a seismically isolated building, and based on the structural calculation results, a structure is calculated regarding a seismically isolated building (the illustrated example is a basic seismically isolated building) having a predetermined seismic resistance performance. It is assumed that a BIM model has already been created.

As shown in FIG. 12, a base isolation building has a base isolation layer SL between a base frame S1 constituting the foundation and an overlying frame S2, and a base isolation layer SL is fixed on top of the base frame S1. The seismic device IS supports the superstructure S2. Although there are a plurality of seismic isolation devices IS in the seismic isolation layer SL, the illustrated example shows one of the seismic isolation devices IS and its surroundings in an enlarged manner. In reality, for example, the seismic isolation device IS is attached to each of the points of X1 street to Xn street and Y1 street to Yn street that are orthogonal thereto in a foundation plan or the like. As shown in FIG. 12, in the upper frame S2 composed of floor beams etc., columns C and walls (not shown) are arranged directly above the seismic isolation device IS. Refers to the entire structure of a building, including floor beams, columns C, walls, etc.

As shown in Figure 12, various types of piping through which fluids such as cold water and air flow are attached to the seismic isolation layer SL. It is included in the BIM model by the facility design user.

In FIG. 12, a foundation-side mount R1 is fixed to the upper surface of the base frame S1 with anchor bolts (not shown), and an upper frame-side mount R2 is fixed to the lower surface of the upper frame S2 with anchor bolts (not shown). ing. By bolting straight pipes P and bent pipes BP (elbows) to each other, a desired linear piping (an example of a connecting member) is constructed, and the piping is connected to the foundation side mount R1 and the upper frame side mount R2. By fixing the parts, piping (piping system) extending from the upper frame S2 to the base frame S1 is provided.

Here, in the piping constituting the seismically isolated building, flexible piping FP1, FP2 that can be deformed to follow the deformation when the seismic isolation device IS is deformed during a major earthquake, for example, are interposed at intermediate positions. Due to the presence of flexible piping FP1 and FP2 at appropriate locations in the piping, for example, when the base frame S1 vibrates greatly relative to the overlying frame S2 and the seismic isolation device IS is greatly deformed due to this vibration, the entire piping will be damaged. It becomes possible to follow the deformation of the base body S1 etc. without being damaged.

In the flowchart shown in FIG. 11, objects such as separate piping and various devices are further arranged in the base isolation layer SL shown in FIG. 12 (step S10).

When the object is placed in step S10, the determination unit 540 determines whether or not this object exists in the operating range of the seismic isolation device. As shown in FIG. 12, the seismic isolation device IS has an operating area around it (in a 360 degree direction), and attribute information shown as an example in FIG. 9 is stored in the storage section 560 (storage step).

The determining unit 540 refers to the operational area included in the attribute information of the seismic isolation device IS stored in the storage unit 560, and determines whether the added object interferes with this operational area (step S12, (judgment process).

As a result of the determination by the determination unit 540, if it is determined that the added object does not interfere with the operating range of the seismic isolation device IS, the arrangement of the object is determined (step S14). On the other hand, if it is determined that the added object interferes with the operating range of the seismic isolation device IS, an error display is performed on the display unit 550 based on a command from the CPU 502 (step S16, display step).

If an error is displayed on the display unit 550, the facility design user changes the installation position of the object so that the object does not interfere with the operating range of the seismic isolation device IS (step S18). After the object is relocated, step S12 is executed again, and if it is determined that the object does not interfere with the operating range of the seismic isolation system IS, the object placement is determined (step S14).

Note that the design support method shown in FIG. 11 is also a series of processing flows executed in the design support apparatus 50, but the design support apparatus 50 is configured by installing a program including this series of processing flows on a computer. may be done.

[Design support method according to second embodiment]
Next, an example of the design support method according to the second embodiment will be described with reference to FIGS. 13 to 15. Here, FIG. 13 is a flowchart showing an example of the design support method according to the second embodiment. Further, FIG. 14 is a diagram showing various examples of seismic isolation piping, and FIG. 15 is a perspective view showing an example of installing cables in a seismic isolation layer.

The flowchart shown in FIG. 13 is executed subsequent to the flowchart shown in FIG. That is, the design support method according to the second embodiment is based on the design support method according to the first embodiment, and after it is determined that the added object does not interfere with the operating range of the seismic isolation device IS, Furthermore, this is a design support method that performs another determination.

Specifically, the determination unit 540 determines whether the added object is a communication member (step S20). Here, the communication member is a member such as a pipe that spans the base frame S1 and the overlying frame S2. For example, based on the attribute information of the connection member, the installation position may indicate a part of the base structure S1 and a part of the overlay structure S2, that is, from a part of the base structure S1 to a part of the overlay structure S2. When the determination unit 540 determines that the object is extending, it is determined that the object is a communication member.

If it is determined that the added object is a connecting member, then the determining unit 540 further determines whether the connecting member is a deformable member (step S22).

Here, FIG. 14 shows various flexible piping as an example of a deformable member. In FIG. 14, (A) shows a horizontal single type straight SUS flexible pipe FP11, a horizontally curved rubber flexible pipe FP12, and a vertically curved rubber flexible pipe FP13. Both of these figures show a state in which they are fixed to the foundation-side mount R1 and the upper frame-side mount R2. Here, "flexible piping" includes flexible hoses, flexible joints, and the like.

Further, (B) shows a form in which a horizontal damper HD is attached to the flexible piping FP14 having a linear shape orthogonal to the horizontal direction. The horizontal damper HD prevents the flexible piping FP14 from being excessively deformed in the horizontal direction, and also allows the deformation to quickly converge.

Moreover, (C) shows the form in which the vertical damper VD is attached to flexible piping FP15 which has a linear line perpendicular to the horizontal direction. The vertical damper HD prevents the flexible piping FP14 from being excessively deformed in the vertical direction, and also allows the deformation to quickly converge. Note that both the horizontal damper HD and the vertical damper HD may be attached to the flexible pipe extending in the horizontal direction or the vertical direction.

Furthermore, (D) shows a vertical single type straight flexible pipe FP16 made of SUS and a vertically curved flexible pipe FP17 made of rubber.

In this way, when the communication member is a pipe (piping system), there are various forms in which the pipe is a deformable member. Although not shown, the determining unit 540 determines as attribute information of the connecting member, which is an object, the presence or absence of a material type such as rubber or SUS, a description indicating that it is deformable, a maximum deformation amount, and the like.

On the other hand, FIG. 15 shows an installation example where the communication member is a cable. The illustrated seismic isolation layer SL is provided with a plurality of cable racks CR spanned in the direction in which the cables CB extend, and the cables CB are arranged on top of each cable rack CR. There is an extra length EL in the middle of the cable CB, and the extra length EL prevents excessive tension from acting on the cable CB and damaging it when the seismic isolation device IS is deformed. can be resolved. Therefore, when the object that is a communication member is a cable, the determination unit 540 determines whether or not there is a description such as the presence of an extra length EL and the length of the extra length EL as its attribute information.

If the determining unit 540 confirms that the communication member is a deformable member, the design support method according to the embodiment ends. On the other hand, if the determining unit 540 cannot confirm that the communication member is a deformable member, an error display is performed on the display unit 550 based on a command from the CPU 502 (step S24).

Here, "cases in which it cannot be confirmed that the contact member is a deformable member" means a case where there is no information indicating that the contact member is deformable as in the above example as attribute information of the contact member, or a case where it is not possible to confirm that the contact member is deformable. This includes cases where the truth or falsity of the existence of information indicating that

If an error is displayed on the display unit 550, the equipment design user checks the attribute information of the connecting member and, if necessary, changes the attribute information to the material type, description of deformability, and maximum deformation amount. , the length of the extra length, etc. are added (step S26).

Note that the design support method shown in FIG. 13 (more specifically, the design support method shown in FIG. 13 following FIG. 11) is also a series of processing flows executed in the design support device 50; The design support device 50 may be formed by installing a program including the following into a computer.

[Design support method according to third embodiment]
Next, an example of the design support method according to the third embodiment will be described with reference to FIGS. 16 to 20. Here, FIG. 16 is a flowchart showing an example of the design support method according to the third embodiment. Moreover, FIGS. 17 to 20 are diagrams showing operating ranges in various flexible pipings.

The flowchart shown in FIG. 16 is executed subsequent to the flowchart shown in FIG. 11 and the flowchart shown in FIG. 13. The illustrated example shows the form executed following the flowchart shown in FIG. 11, and the design support method according to the third embodiment is based on the design support method according to the first embodiment, and the added object In this design support method, after it is determined that the seismic isolation device IS does not interfere with the operation range of the seismic isolation device IS, another determination is further performed. The design support method according to the third embodiment is based on the premise of the design support method according to the first embodiment and then the design support method according to the second embodiment, and the added object is the seismic isolation device IS. The design support method may further include performing another determination after it is determined that the connecting member does not interfere with the operating range of the connecting member and it is further confirmed that the connecting member is a deformable member.

Specifically, the determination unit 540 determines whether the added object exists in the operating range of the communication member (step S30).

Here, as mentioned above, there are various forms of flexible piping, and the operating range of the connecting member is set differently depending on each form.

Each of the piping shown in FIGS. 17 to 20 is a piping through which water supply, cold water, cooling water, etc. are distributed. First, in the piping shown in FIG. 17, two flexible piping FP20 and FP21 are connected via an elbow BP and extend while being bent in the horizontal direction, as shown in FIGS. 17(b) and (c). It is fixed to the upper frame side frame R2 and the foundation side frame R1 above and below, and is suspended from the upper frame S2 by a vertical damper VD. The dashed-dot line range in the plan views and side views in two directions in FIGS. 17(a), (b), and (c) is the operating range SP of the piping. The attribute information of the piping (piping system) consisting of the flexible piping FP20, FP21 and the elbow BP includes information regarding this three-dimensional operating area SP, and the determination unit 540 confirms the information regarding this operating area SP. be able to. In addition, in FIG. 17, "L" is, for example, the length of the flexible pipe, "A" can be set to, for example, seismic isolation amount + outer diameter of the flange connecting the pipes x 0.5 + 100 mm, and "B" is the length of the flexible pipe. For example, the length of the flexible piping + the length of the vent pipe (elbow) can be set for "C", and for example, the amount of seismic isolation from the end of the flexible piping can be set for "C". Moreover, for example, the minimum piping installation height can be set in "H".

Furthermore, in the piping shown in FIG. 18, elbows BP are connected to the upper and lower ends of the SUS flexible piping FP22 that extends in the vertical direction, and straight pipes P that extend in the horizontal direction are connected to each elbow BP. ing. Since the flexible piping FP22 is deformable in the 360 degree direction, as shown in FIG. 18(b), which is a view in the b direction of FIG. The flexible piping FP22 can follow the movement in the degree direction. Therefore, the working area SP when viewed from the side is a triangular area shown in FIG. 18(a), and the working area SP when viewed from above is the diameter φD as shown in FIG. It becomes a circular range.

In addition, in the piping shown in FIG. 19, elbow BPs are connected to the upper and lower ends of a curved flexible piping FP23 made of rubber that extends in the vertical direction, and a straight pipe P that extends in the horizontal direction is connected to each elbow BP. It is connected. Since the flexible piping FP23 is deformable in 360 degree directions, as shown in FIG. 19(b), which is a view in the b direction of FIG. The flexible piping FP23 can follow the movement in the degree direction. Therefore, the operating range SP when viewed from the side is a triangular range shown in FIG. 19(a), and the operating range SP when viewed from above is the diameter φD as shown in FIG. It becomes a circular range.

Further, in the piping shown in FIG. 20, a straight pipe P extending horizontally, an elbow BP, and a straight pipe P extending vertically are connected to both ends of the U-shaped flexible piping FP24 extending horizontally. ing. As shown in FIG. 20(b), when the base frame S1 and the overlying frame S2 vibrate to move closer to each other in the vertical direction, the flexible piping FP24 shrinks by a width M in the vertical direction, and at the same time contracts by a width M in the horizontal direction. The operating range is set by taking these factors into account.

In this way, information regarding the operating range according to the applied piping (or piping system) is described as its attribute information.

Returning to FIG. 16, in the flowchart shown in FIG. 16, for example, when additional objects such as piping and various equipment are placed in the seismic isolation layer SL shown in FIG. The determination unit 540 determines whether the member (for example, piping) is present in the operating range.

The determination unit 540 refers to the operation area included in the attribute information of the piping (or piping system) stored in the storage unit 560, and determines whether the added object interferes with this operation area (step S30).

As a result of the determination by the determination unit 540, if it is determined that the added object does not interfere with the operating range of the already installed communication member, the arrangement of the object is determined (step S32). On the other hand, if it is determined that the added object interferes with the operating range of the already installed communication member, an error display is performed on the display unit 550 based on a command from the CPU 502 (step S34).

If an error is displayed on the display unit 550, the equipment design user changes the installation position of the object so that the object does not interfere with the operating range of the communication member that has already been installed (step S36). After the object is rearranged, step S30 is executed again, and if it is determined that the object does not interfere with the operating range of the communication member that has already been installed, the object placement is determined (step S32).

The design support method shown in FIG. 16 (more specifically, the design support method shown in FIG. 16 following FIG. 11 and the design support method shown in FIG. 16 following FIGS. 11 and 13) is performed in the design support device 50. Although it is a series of processing flows to be executed, the design support device 50 may be formed by installing a program including this series of processing flows into a computer.

[Design support method according to fourth embodiment]
Next, an example of the design support method according to the fourth embodiment will be described with reference to FIGS. 21 to 24. Here, FIG. 21 is a flowchart showing an example of the design support method according to the fourth embodiment. Further, FIGS. 22 to 24 are diagrams showing examples of various constraints.

The flowchart shown in FIG. 21 is executed subsequent to the flowchart shown in FIG. That is, the design support method according to the fourth embodiment is based on the design support method according to the first embodiment, and after it is determined that the added object does not interfere with the operating range of the seismic isolation device IS, Furthermore, this is a design support method that performs another determination.

Specifically, the determining unit 540 determines whether the distance between the added object and the adjacent object is less than the minimum distance (step S40).

Here, as shown in FIG. 22, it is assumed that two pipes, one pipe P10 and the other pipe 20, are arranged with an interval between them. The minimum separation length of the piping is set based on various constraint conditions. These conditions include laws and regulations (such as the Fire Service Act), the space for applying the moisturizing material, the location of connections to other equipment, and internal company rules. The minimum separation length of the piping is also described in the attribute information of the piping, and the determination unit 540 can confirm this attribute information.

For example, as shown in FIG. 22(A), when the piping P10 and the piping 20 have a distance DS1 equal to or greater than the minimum separation length, the determination unit 540 determines whether the added object and the adjacent object are It is determined that the separation length between them is equal to or greater than the minimum separation length, and the arrangement of the additional object is determined (step S42).

On the other hand, as shown in FIG. 22(B), when the piping P10 and the piping P20 have a distance DS2 that is less than the minimum separation length, the determination unit 540 determines whether the added object and the adjacent object are separated from each other. It is determined that the separation length between them is less than the minimum separation length, and an error display is performed on the display unit 550 based on a command from the CPU 502 (step S44). In addition, in FIG. 22(B), a warning display ME indicating that "the interval violates the rule" is displayed.

If an error is displayed on the display unit 550, the facility design user changes the placement position of the object and installs the object so that the distance between the object and the already installed object is equal to or greater than the minimum distance. The position is changed (step S46). After the object is rearranged, step S40 is executed again, and if it is determined that the distance between the object and the already installed object is greater than or equal to the minimum distance, the object placement is determined. (Step S42).

Note that the design support method shown in FIG. 21 (more specifically, the design support method shown in FIG. 21 following FIG. 11) is also a series of processing flows executed in the design support apparatus 50; The design support device 50 may be formed by installing a program including the following into a computer.

Further, constraints may be set as shown in FIGS. 23 and 24. In the constraint example shown in FIG. 23, when a duct is selected for change and size change is selected, a GUI (Graphical User Interface) for changing the duct type as shown in the figure is displayed. This is an example. That is, the GUI is a setting screen PSET etc. that allows changing various specifications regarding the duct. Specifically, the setting screen PSET is configured by providing a so-called pull-down menu or the like for each parameter that can be set.

In the illustrated example of the setting screen PSET, settings can be made to select the shape, etc., such as "round duct." Similarly, in the illustrated example of the setting screen PSET, settings can be made to select the type, such as "air supply duct." Further, in the illustrated example of the setting screen PSET, settings can be made to select the volume of fluid to be sent per unit time, such as "1,100 m ³ /h". Further, in the illustrated example of the setting screen PSET, settings can be made to select the size, etc., such as "300". Note that the types that can be set are not limited to the illustrated example.

Next, with reference to FIG. 23, a pull-down menu PL1, which is an example of a GUI for selecting "size", will be described. In this example, it is first assumed that the rules stipulate that the unit pressure loss for duct installation be 1.0 Pa/m or less. Based on this rule, a size less than "300" is considered to be a rule violation. In such a case, the pull-down menu PL1 is set so that a size smaller than "300" cannot be selected. That is, as a rule check result, a size less than "300" is determined to be a rule violation. By reflecting this check result, even if a size smaller than "300" is available for purchase, it is not displayed on the menu as shown in the figure. In this way, by reflecting the rule check results on the GUI, etc., the user is prevented from making changes that violate the rules.

On the other hand, the constraint example shown in FIG. 24 is an example in which a size smaller than "300" violates the rule based on the rule for installing a duct, similar to FIG. 23. However, the method of reflecting the check results is different from that shown in FIG. 23, and as shown in the figure, this is an example of a constraint that indicates sizes that violate the rules by color coding. As shown in the figure, sizes “200” and “250” that are smaller than “300” are displayed in different colors from sizes that are larger than “300”. In this way, by distinguishing the sizes that violate the rules by color-coding or the like, the user can understand the changes that violate the rules. Note that if multiple rules are set, the check results may also differ. For example, in one rule, a size of "200" is a check result that violates the rule (hereinafter referred to as "first check result"), while in another rule, a size of "250" is a violation of the rule. It is assumed that the check result (hereinafter referred to as "second check result") is as follows. In this way, when the check results are different for each rule, the respective check results may be displayed in different colors as shown in the figure.

The illustrated example is an example in which the first check result is displayed in the first color C1, and the second check result is displayed in the second color C2. As in this example, by color-coding each check result into the first color C1 and second color C2, it can be seen that a violation has been determined based on different rules. Note that the constraint method is not limited to color-coding items that violate the rules as shown in the figure; for example, it may display an error when an item that violates the rules is selected, or it may display items that violate the rules by color. It may be emphasized, hatched, or grayed out.

It should be noted that other embodiments may be adopted in which other components are combined with the configurations listed in the above embodiments, and the present invention is not limited to the configurations shown here. In this regard, changes can be made without departing from the spirit of the present invention, and can be appropriately determined depending on the application form.
