Selecting an entire edge loop in triangulated OBJ meshes from CAD

systembolaget — Mon, 08 Nov 2021 11:16:10 GMT

Selecting an entire edge loop by double clicking or selecting an edge on one side and shift selecting one on the other to select an entire edge loop does not seem to work with triangulated OBJ meshes from CAD.

Is there a way to do it instead of "woodpeckering" the Grow Selection Along Loop button for very long edge loops? Only with the entire edge loop selected, the UV shell can be straightened out with the Straighten Shell command.

Standard selection tools wont work on triangles. You might wish to Quadrangulate first - will work on your given example, not on more random edge distribution.

Uh, no joy with triangle meshes from CAD then. Quadrangulating works only on extremely basic meshes. So "woodpeckering" is a bit tedious, but works ; )

Could one not write a MEL script that does the "woodpeckering" for the user?

Well, you probably can substitute woodpeckering in uvEditor with Select > ShortestEdgePathTool.

Thanks, that works.
