I am getting the same error messages when trying to form a wall, structure or panel from a d-wire.

Thanks, I was able to solve the problem with the information in this link.

The help documentation files are in their correct location in the "DOC" folder. If they are not then a different error message is displayed indicating so.
I tried going back to the previous build of version 18 and this did not solve the problem and now version 17 is doing the same thing.

I am having the same problem with the F1 Help key.

I was incorrect when I said it looks like the problem only occurs on Windows 32bit machines. I upgrade from Windows 32 bit to Windows 64 bit and experienced the same error. I observed that on every machine where the error occurs I get "Mod\Measure\Initgui.py not found" during initializatio...

I'm having the same problem, see issue # 3423. I have tried installing FreeCad v0.17 on 5 different machines running Windows 10 both 32 bit. At first I thought it might be the 32 bit version of Windows but after upgrading to the 64 bit version I still get an error when trying to create a wall. One o...

I also tried it on a machine running windows 7 32 bit and it worked fine. It seems the problem occurs under windows 10 32 bit. I tried replacing the file "ArchWall.PY" from v17.13488 with the file from v17.7745. This fixed the 3D viewing problem but unfortunately caused other problems so i...

The direction of rotation when forming the dwire does indeed seem to be affecting the results. When I construct the same dwire starting at the origin (0,0,0) and ending at the origin (0,0,0) but drawing in a clockwise rotation the wall forms correctly. Experimenting further I found that if the first...

After further testing there seems to be a problem with the forming of the dwire. Wall from Closed Dwire.PNG I drew the dwire starting at the origin and placed the vertices in a counter clockwise rotation and ended back at the origin which is the way it appears in the 3D view. Looking at the combo vi...
