Walls seem to be the most basic cause of problems. In the structural wall, the lower wall should be visible as a hidden line.
So I have to choose All Revelant Stories for the walls. (If there is another way, please let me know)
The only way I could solve this problem was with GOC. So I was able to select the lower wall line by specifying WALL, Home Story. And I had to designate the pen as number 19.
Question 1. I would like to know why I cannot select 0,-1. And by selecting number 0, we want the lines to disappear. (If it cannot be deleted by specifying number 0, etc., it will be added to the wishlist.)
Question 2. When exporting dwg, is there a way to not export this line 19 to dwg? (Is the only way to write a program such as Autolisp to delete layers with the number 19 in the layer name?)
When I set it to number 19, it did not disappear but appeared in the CAD file. So the way I can do it is to turn it off in Autocad.
And the problem is that even when exporting to dwg, the overlapping lines are exported without any processing. I think I can handle it, but I don't think I can. This is a question often asked by BIM haters. There are so many lines in REVIT. If this happens, I think there will be a lot of lines that ArchiCAD will need to support as well. I don't know if it's a PDF, but in Korea, the RVT and PLN files that were delivered as DWG should be delivered quickly.
