Archived issue #0027785
Thickness operation "warps" shape at seam edge
Description
Applying a thickness on this special cylinder + draft + fillet part creates a deformed shape at the seam edge. There the flat top face gets an evalation. Note tha tthis effect does not appear when one uses different draft settings, it seems this happens only under very specific circumstances. See Issue 0027784 for a quite similar cylinder + draft + fillet + thickness operation that works fine.

The problem was found with FreeCAD 0.17 and OCC7.0.
Note that somehow the provided draw script does not work with the "source" command, but copy paste into draw.exe works.

The script contains an error - the command "dep" is not found. Shortened names of commands are not allowed in a script. I have updated it.
Interesting note from our discussion @FreeCAD forum:
"Export this file to stp and after open in any CAD is geometry all right. Probably is issue in graphics rendering."

It is not rendering error, because we can see the hanging end of an edge in the draw view (see the attached Attachment 1 (PNG)).
The issue is still reproduced in OCC7.2 beta
