Closed, degenerate or unsupported 3D faces

[Anonymous]

Hello all,

Essentially, my drawing contains thousands of 3D faces. Some of them are "closed, degenerate or unsupported objects" and are causing problems.

I want to either be able to:

- identify closed, degenerate or unsupported 3D faces and fix them (whatever that means - figure out the problem and reconstruct)

- identify degenerate 3D faces and delete them

I came up with a potential workaround. I make a copy of the faces and run region command. It will convert all faces except those that are "closed, degenerate or unsupported objects". Now I need to identify these in the drawing containing all the 3D faces.

One way is to copy the identified problem faces into the original drawing. Now we have duplicates on top of each other. Erasing all of those identical faces would mean that only proper ones remain. Not getting rid of duplicates as in overkill, but deleting both the original and its duplicate.

Attached you can find a simplified version of the situation I described. In this particular case, duplicate 3D faces share identical values for vertex x, y and z for all 4 vertices they are comprised of. How do you automate identifying and deleting these?

Any ideas?

Thanks,

Samu

You can use SelFace to detect all kinds of "strange" 3Dfaces but your drawing looks quite good there.

The message "closed, degenerate or unsupported objects"  i know only from command region, but this is not the command you want to run.

I think you have to find the Problem first, if there is no solution you can search for an workaround like Region->Copy left 3DFaces-> "select doubles"

Which command are you trying and get "closed, degenerate or unsupported objects"  as feedback from the program?
