Hello Everyone.
Well, here is what I would like to do : I’d like to cut a wall at a specific point.
I tried many ways to do this, but is there a fonction (like the one in revit) so we cut a selected wall at a specific point?
No you wil have to build your own.
Move the previous wall to a new location line from the start point to the split point, then make a new wall by the line from the split point to the end point. This is kinda how the split wall (or pipe, duct, detail line, etc) works - adjust the location of the old element and make a new element accordingly.
