Ok. We work with a lot of surface files from RXXXX that are imported through IGES. Often, we get duplicate surfaces on a face. Is there anyway to "purge" duplicate surfaces automatically?
Don't know the exact answer to your question, but I will say that no one I know uses IGES anymore (in the last 10 years). It's all STEP or Parasolid now. I'd suggest trying to move to STEP for example...
Thanks for the reply. We definitely agree that STEP is the preferred method for translating but unfortunately we don't always control what we have to import.
As always, there are work arounds!
We still use IGES. IGES for single file and STP for assemblies. few of our small tool suppliers request IGES.
Did you try opening the IGES and then saving as STEP?
Then open the STEP with every option checked except Boolean solids.
Experiment with options when you save and re-open.
I have tried the export as STEP and then re-opening the STEP but without much success. The native file is, for lack of a better term, so broken up that it did not help. In fact some of the surfaces I could not even edit them (extend, trim, etc). IN the end of the day, we end up re-drawing a lot of the geometry so that we can stitch it together.
