By doing this, it is possible to calculate the quantity of the unit of the zone based on the position and the member name of the member included in the three-dimensional model information of the object line corresponding to the area coordinate information of the zone box in the small area, In addition to enabling job management and work order creation, it is possible to utilize the quantity of small-unit units in the process management in the post-production department, thereby improving the overall production quality.
In the above description, when an arbitrary region is selected in the section tree, the 3D model information of the selected region is displayed on the second screen, and it is determined whether there is a section box at a lower node of the selected section. Dimensional modeling information having the coordinate information coinciding with the coordinate information of the three-dimensional modeling information, and the position of the member. However, in another embodiment, the quantity of the product can be calculated through visualization of the model.
Prior to calculating the quantity, the work model has a logical connection to the section tree associated with the quantity of the small unit to be calculated.

If the option in the corresponding zone is a complete include option and the bounding box of the working model is completely included in the zone coordinate information of the zone box, the option file is satisfied. In other cases, if the option of the corresponding zone is not completely included and the bounding box of the working model is at least partially included in the zone box information of the zone box, the option file is added to the file open list.
In other cases, that is, when the bounding box of the working model is not completely included even though the area option is completely included. If the bounding box of the working model is not included in the area coordinate information of the area box, Do not add model files.
If the zone coordinate information of the zone box exists in the bounding box list of the model, the zone coordinate information of the zone box is extracted again on the bounding box list of the model, and if the next work type file exists on the work type file list, The process of loading the bounding box of the work model is repeated.
When this process is repeated, the work type file added to the file open list is loaded and the work type model loaded on the second screen is visualized. In this case, since the logical connection relation between the work type model and the zone box is defined, the quantity of the selected node can be calculated based on the member name and the position of the member of the work model corresponding to the zone coordinate information of the zone box.
