Hi all,
I have a complex swept part, about 35' x 15' profile with a swept section about 2' tall and 1' wide. It's analogous to a giant crown molding in looks.
I have split the part into about 20 pieces for mold making/casting. The parts are being exported as IGES files for the fabricator.
I want to compare the iges files to ensure they are identical.
I open the original part and then open it's iges counterpart and do a 'geometry compare'. It almost every case the volume is 'identical' but there are almost always 'unique faces' listed.
In my mind if the volume is identical that should be good enough? I take it to mean that the unique faces are so close to one another that boolean operations are impossible and I should be happy that it's all Good Enough (tm)!!
Do you all agree?
Here is a snippet from the report of a sample part:
Reference Part Modified Part Unique Face(s) 8 8 Modified Face(s) 1 1
Volume Comparison
The solid volumes of both the bodies are identical.
