Description

Description: BACKGROUND OF THE INVENTION The present invention relates to the design of detached houses in the field of construction, and in particular to the representation of the shape of a roof, ie the roof plan.

[Conventional technology]

Conventionally, the purpose of the Computer Aidded Desing system (hereinafter abbreviated as CAD) in the architectural field is to mainly output drawings, for example, rooftop plans are represented by simple line segments, so they correspond to the rooftop plans The three-dimensional shape to be created may not be uniquely determined. Therefore, other drawings (such as elevations) may be required to represent one roof.

[Problems to be solved by the invention]

In the conventional roof shape representation described above, the three-dimensional roof shape was represented as a roof plan with a line segment without a characteristic, so if the three-dimensional shape was determined, it could be represented in a planar manner, There is a drawback that a plane representation cannot be made to correspond to a three-dimensional shape. In other words, since it does not correspond one-to-one, it is necessary to look at it with other drawings to make it correspond. The fact that it is not uniquely determined means that it is not suitable for mechanical processing, and other information (direction of surface inclination, magnitude of inclination, etc.) is required to perform mechanical processing. This causes the input operation of the roof plan input device to be troublesome.

[Means for solving the problem]

The roof plan input device according to the present invention includes an input for designating a type of a line segment expressing a roof, a start point and an end point of the line segment, a height of the roof, a reference point of the height, and a slope of a surface of the roof. Means, command analysis means for analyzing the data inputted by the input means and determining the next processing, storage means for storing the data, and whether or not the roof is constituted by the data according to the processing result of the command analysis means And a shape display means for displaying the data together with the check result of the logic check means on a screen to confirm the design status of the roof.

〔Example〕

 FIG. 1 shows an embodiment of the present invention.

In FIG. 1, data input devices are a keyboard 1, a tablet 1a, and a pen 1b. The keyboard 1 is used to input the magnitude of the inclination of the roof surface and the height of the roof surface reference point. The tablet 1a and the pen 1b select a command, select a type of a line segment to be input, and indicate input coordinates. Tablet
In 1a, the input area is divided into squares, and commands and line type data are assigned to each square. These input devices are connected to the input control unit 2.

The input control unit 2 controls whether the input from the keyboard 1 is valid, the input from the tablet 1a is valid, and whether the command is received or the coordinate or other data is received.

The command analysis unit 3 determines an operation to be executed next based on the received data.

The roof configuration logic check unit 4 performs a logic check for each roof surface of the configured roof.

The screen display control unit 5 causes the screen display device 6 to perform display. Here, selection of data to be displayed and conversion processing are performed.

The screen display device 6 displays the input data and informs the designer.

The storage device 7 stores data relating to the roof, such as input line type data and coordinate data.

The data input from the keyboard 1 or the like is determined by the command analysis unit 3 as to whether it is a command, line type data, or coordinate data.
The next operation to be executed is determined based on the received data. If it is a command, the operation is started. If it is coordinate data, if it is the start point, the data is temporarily stored, and the input control unit 2 is processed to wait for input of the end point coordinates. If it is the end point, the line type data and the coordinate data are sent to the screen display control unit 5. The data is stored in the storage device 7. Here, the screen display control unit 5 performs appropriate data conversion (mainly coordinate conversion) and causes the screen display device 6 to perform display.

The operation of the roof configuration logic check unit 4 is started when a roof data input end command is input. Here, the data stored in the storage device 7 is checked. A hatch is applied to a surface configured without contradiction. Further, the surface information is stored in the storage device 7.

Commands have various functions to facilitate input operations. Specifically, input cancellation, input data deletion (line segment deletion), input data change (line segment movement), input guideline (input auxiliary line) display, and the like.

 Next, a specific example will be described.

First, the standard value of the roof is set. Eave shape (slope or vertical), eave shape (slope or flat), (roof finish (tile or color best), eave dimensions, gable dimensions,
Enter the dimensions of the single-story building, eave height on the first floor, eave height on the second floor, eave height on the third floor, roof slope, and thickness of eaves and gables by entering them from the keyboard 1. The set value is stored in the storage device 7.

Next, an auxiliary line is input as preparation for inputting the roof shape. In other words, enter the eaves, gable, climbing valley, and auxiliary line of the climbing ridge. As an example, input of an eaves auxiliary line will be described. Set the area of the eaves auxiliary line in the command area on the tablet 1a. The coordinates of the hit are sent to the command analysis unit 3, and are analyzed as the eaves edge auxiliary line command. When the command is analyzed, the input is controlled by the input control unit 2 in a sequence corresponding to the command. For the eaves front auxiliary line, two points (start point, end point) on the wall and the direction of the outgoing are input by the tablet 1a. Input is performed by hitting the tablet 1a with the pen 1b, but the position of the pen 1b is always displayed on the screen by a cross cursor. When the input is completed, the coordinates of the start point and the end point of the actual auxiliary line are calculated, the element ID (in this case, the auxiliary line of the eaves), the coordinates of the start point and the end point are stored in the storage device 7, and further transmitted to the screen display control unit 5. Can be When the data is sent to the screen display control unit 5, the screen display device 6 displays the data. The necessary auxiliary line is input in the same manner.

Next, a roof line is input. Take eaves as an example. Hit the eaves entry area of tablet 1a. When a hit occurs, the coordinate data at that position is sent to the command analysis unit 3, which analyzes that this is an eaves front input command. When it is analyzed that the command is an eaves destination input command, the input control unit 2 starts inputting a start point and an end point. The starting point and the ending point are determined by the tablet 1a and the pen 1b as in the case of the auxiliary line. In the same manner, input a necessary roof line.

Finally, enter the roof height. The position of the reference point of the height of the roof surface is indicated by the tablet 1a. When the roof height is specified, the roof line including the point is searched from the data stored in the storage device 7. When the roof line is searched, the roof configuration logic check unit 4 checks whether the roof line is closed, and if it is closed, whether there is any contradiction as the roof surface. When a roof surface is configured, the surfaces that are in contact with the surface are checked one after another. When a surface is configured, the screen display control unit 5 is instructed to hatch the surface.

When all the processes are completed, the data stored in the storage device 7 is output to the disk device 8.

〔The invention's effect〕

By characterizing the line segment and expressing it in a specific way (for example, expressing a line segment with a gradient with an arrow going from a low position to a high position), while checking the CRT one after another Correction work such as input, addition, and deletion can be easily performed. Although the expression is two-dimensional, the shape can be determined three-dimensionally. Therefore, the three-dimensional shape is determined without misunderstanding even if the roof plan and the elevation are not viewed as a pair. Also, the number of drawings as a means for expressing the roof is sufficient for this one. Further, since the configuration of the roof is checked when the roof height is input, inconsistencies in the configuration can be eliminated.
