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

âQuad 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:
- in Edit Mode, select the mesh you want to convert and use Alt + J or from the Faces special menu with Ctrl + F > Tris to Quads to convert tris to quads
â
or with InstantMeshes
â
or in MeshLab
The simplest and best result is InstantMeshes, but it still depends on what you need.
If you simply go around and âsoftenâ the diagonal edges on your model, then thatâs 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.

nor is a square in 3D graphics, everything is made from trianglesâŚ
within SU, Fredoâs tools generate Quads as they comply with TTâs definition used by most extension authors that utilise SU quadsâŚ
from the linkâŚ
Native quad face, face with four vertices.
Two triangles, joined by an edge with the following properties:
Soft = true
Smooth = true
Cast Shadows = false
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 wasnât a stated requirement in the OPâŚ
@ecati, do you wish to âexportâ a different form of âquadâ definition?
first, you need to move all the edges to the same layer, Layer0 is deemed best for raw geometryâŚ

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.

Iâm not sure I understand exactly what you are after, is it true quads or SU Quads. Sketchup doesnât actually have true quads, they are always triangulated.
QFTâs Convert Triangulated Mesh to Quads doesnât always get them right, but you can harden the edges on the wrong ones and go again.
