Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing management device, and more particularly, to a drawing management device that manages drawing components constituting a drawing as graphic data and image data and synthesizes and displays these.

[Prior Art] Digitization of drawings is roughly classified into digitization into graphic data (graphic data) and digitization into image data (image data conversion). By converting the data into graphic data, it is possible to recognize individual graphics that are drawing constituent elements of the drawing. Therefore, it is possible to search the attribute data of the drawing constituent element by specifying the drawing constituent element. However, the cost required for converting to graphic data is large.

On the other hand, if the image data is converted into image data, the cost required for the image data conversion is small, but the drawing constituent elements in the drawing cannot be linked with the attribute data.

Among the drawing components included in the drawing, there are drawing components that need to be associated with the attribute data and drawing components that do not require individual recognition and can be simply restored. The former is desired to be converted into graphic data, and the latter is desired to be converted into image data from the viewpoint of cost.

Conventionally, in this type of drawing management apparatus, graphic data and image data are handled separately, and drawing components of one drawing can be handled only in one of the forms. Therefore, if you want to recognize individual drawing components, handle all drawing components of the drawing as graphic data (CAD system, etc.), and if you need to recognize each drawing component, handle the entire drawing as image data. (E.g. electronic filing system).

[Problems to be Solved by the Invention]

In the above-described conventional drawing management device, drawings are managed in the form of either graphic data or image data, so that only drawing constituent elements that require a relational search with attribute data in one drawing. Is managed as graphic data and the entire drawing cannot be combined and displayed with the managed image data separately, and one drawing is considered in consideration of the balance between the functionality of the graphic data and the economical cost of the image data. It has the disadvantage of not being able to manage.

In view of the above points, an object of the present invention is to consider a balance between functionality and cost efficiency by managing only a part of drawing components of a drawing as graphic data and enabling composite display with image data. It is to provide a drawing management device capable of managing drawings.
