Hi All,
Just a bug file here - It's been a while since I found something like this -
A red piece and a white piece - Select union, then both of them.
Expected result - Parts union, erasing existing holes at the top of the flange.
Experienced result - Operation fails with the following error.
Error details:
: _UNION1 found, 2 totalThe Boolean operation on solids failed.Modeling Operation Error:Inconsistent edge-face relationships.At least 2 solids or coplanar regions must be selected.:
File attached for example - Both pieces are qualifying solids - The first was the piece I was working on, the second ( in red ) is the part I made to correct it for a new version - It was created be subtracting one cylinder from another. Both pieces are aligned and on the same plane.
Note: Workaround is to build a very large piece and replace the entire top of the flange, then rebuild it from scratch, but that's not exactly a good workaround.
