Hello,

I would like to create a reinforced concrete wall with the area reinforcement tool, but I'm having a hard time with it...
I enter the offset (picture a1), I draw a polygon (picture a2), and after I close the polygon (or hit Esc after the diagonal was drawn) it cancels the command without any error message (picture a3).
I tried this tool in a new project, and it worked fine. I noted that the polygon is represented with only one line, the concrete cover doesn't appear.

What is the cause of the problem?

Thanks in advance!
