#1

Is it possible to make these triangular surfaces to quad surfaces?

âQuad face toolsâ has an option to do that.

at first i thought it was a tube with coplanar faces, but as its a compound curve the quads would need to spiral around it?

Yes, it is!

You could use Blender:

The simplest and best result is InstantMeshes, but it still depends on what you need.

If you simply go around and âsoftenâ the diagonal edges on your model, then thatâs recognised as quads as it is.

I imagine there are numerous possibilities to creating quads for these forms. If you use Curviloft it creates quad geometry and you have the added bonus of a few options with the form of the shape too. I tried Curviloft with the end two rings of your shape.

Iâm not sure about that âgreen check inâ. Not really quad faces.

@mihai.s is right. These are not real quad faces.

nor is a square in 3D graphics, everything is made from trianglesâŚ

within SU, Fredoâs tools generate Quads as they comply with TTâs definition used by most extension authors that utilise SU quadsâŚ

• Native quad face, face with four vertices.

• Two triangles, joined by an edge with the following properties:

• Soft = true

• Smooth = true

• Border edges can have any property, just not all of them.

• Faces that makes up a QuadFace cannot have holes in them.

they may not be seen as quads in other apps, but that wasnât a stated requirement in the OPâŚ

@ecati, do you wish to âexportâ a different form of âquadâ definition?

first, you need to move all the edges to the same layer, Layer0 is deemed best for raw geometryâŚ

When I wanted to do a Tube Map with Sketchuv, it gave an error. So I wanted to ask if these surfaces could be quad. I got Layer0.
