How do I intentionally create lamina faces?

I have been plagued by lamina faces, so I have resolved to set a side my project and learn what causes them, how to visualise them, and finally how to clean them up. I have learnt quite a bit about the subject just by reading the manual and watching some videos. They all essentially use the same technique to clean lamina faces which is, merge vertices with a very low value, then run the “mesh clean up” command.

But now, in a twist of irony, am stuck on intentionally creating lamina faces…Take this video, Hidden Faces, I tried following him to create this undesired hidden face, but am getting a perfectly clean extrusion, its the same with other videos I followed. Am guessing Autodesk improved their commands, considering these videos are quite old.

So, how does go about creating lamina faces?? heck if you have obj models with lamina faces, I would love to have them.

Thanks!

Lamina face are simply faces that share all verts

I just tested this

  • create 2 polyPlanes
  • combine them
  • select the verts and merge

mel to do this:


polyPlane;
polyPlane;
select -r pPlane2 pPlane1 ;
polyUnite -ch 1 -mergeUVSets 1 -centerPivot -name pPlane1 pPlane1 pPlane2; 
select -r pPlane3.vtx[0:241] ;
polyMergeVertex  -d 0.05 -am 1 -ch 1 pPlane3.vtx[0:241];

the same process should work with any poly object:

  • duplicate
  • combine
  • merge verts

So simple also you guys make Mel look so easy.
Its just what I needed to my tests, Thank you for this.
