How to self-stitch a 2D rubber sheet mesh? - ggaliens - 11-21-2012
How to self-stitch a 2D rubber sheet mesh to itself in Wings3D ?
I have a one-side GYROID brought in from Surface Evolver. It has ZERO volume ... presumably HOLE-FACES.
What I have had limited success with is ...
1) Duplicate w/o move ... duplicate using geometry window.
2) Invert the dup object. Now you have faces pointing in both directions.
3) Select all verts on border of one sheet ... invert selection and move normal a little bit each vertex to create the feel of THICKNESS.
4) Combine the two sheets into one object.
5) Weld the two sheets together. Presumably ... only the edge verts have any thickness.
The above process works but is very flakey depending on how smooth original sheet is ... if it is crumply at all and has n-isotropic faces ... then is scary process.
Maybe I should be able to use intrude ?
I want a gyroid with thickness to it.

This is how I ended up having to do it.
0) Remove triangles of small area (think with short edges) near border
1) Duplicate and invert the mesh so original and "mirror" are back to back.
2) Extrude Region on one mesh.
3) Weld Meshes.
I think the keys were (0) and (2). I was doing some move faces normal I think rather
than extrude region. And that was troublesome.

Maybe try Shell Extrude? I think it's the same as you're trying to accomplish.

I thought I had tried shell extrude. I will try it again. Thanks.
