Normals facing both directions

I have a model from Sketchup and it is a closed mesh. However some of the normals are facing in and the others out. Is there a tool to fix that and check it. :slight_smile:


For some reason it did not work on this mesh. Do you know how to select one face of a mesh? Then I could flip that normal manually. Will take some time.

Hello - see if ExtractDuplicateMeshFaces does anything. My guess is it will ‘duplicate’ your mesh…


I think this model is a totally jankie file. But it is what I get a lot of. The extractduplicatemeshfaces extracted a couple of faces.

It would be useful to know how to select a single mesh triangle so i can flip it.

Hello - try RebuildMesh.
