Hello, I have been working with these simple CAD plans for some time, however when I went to measure some areas of our 2D layout I got some weird results. Through investigation I see I have walls extruded into the Z plane (I did not setup this project) - Can I get some advice how to remove all Z plane data and just have everything 2D on X-Y plane?
If I understand correctly, you only had the 2D data and then somehow you ended up with the 3D extrusions that you don’t actually want. Is this correct? In this case, select all the extrusions (Z plane) and hit the Delete key on your keyboard to get rid of them. In Rhino the 2D geometry is independent from the 3D geometry, deleting the one won’t delete the other one.
