I'm expanding on this question I asked previously.
I then want to select and remove all faces on the interior where a face is duplicated. In my previous answer, one user suggested a two step process to select the interior faces:
- Remove Doubles
- Select > Select all by trait > Interior Faces
But that doesn't scale up. If I make a larger object, interior faces includes a lot of incorrect selections.
Is there a way to remove the double-sided faces on the inside of this mesh without using scripting?
