I have a marshmallow shape but I don't like the type of topology it creates when I twist 4 cylinders around each other, using a Mirror modifier on XY (which creates 4 cylinders) and a Simple Deform modifier 360, as seen from the front view. Because I need to divide this shape into half but doing so will create ugly faces at the edge as seen in the below Side View. This shape cannot be subdivided with a subdivision modifier due to the ugly edge.

The yellow line is a cut using the bisect tool, while viewing perfectly orthographically from the side view, to demonstrate the type of quad topology I am looking for. In the 3rd Image you see the type of pretty quad topology I am looking for. Is it possible to model this marshmallow shape with this topology so that it goes around the shape with these nice quads? Either normal modeling or geometry nodes or whatever tools available in Blender.

You can begin with 4 symmetrized half circles:

Then give it a Screw modifier, which should give something like what you want?

At the end, apply the modifier, merge the vertices by distance, cut off the top and bottom with the Bisect tool, you may have to work a bit on the topology:

  • $\begingroup$ Nice thanks for sharing. Is it also possible to have it flat capped at the bottom and top with quads at the edges so that it can be nicely subdivided with subdivision modifier? $\endgroup$

  • $\begingroup$ You need to cut with the Bisect tool for example, then fill with F $\endgroup$
