Why bevelling a grid doesn't result in a perfect circle? I tried every setting I could think of but a fully bevelled grid is far from looking like a perfect circle. However, bevelling edges of a box results in a perfect round shape. I made a screenshot where a perfect circle is green and the bevelled grid is violet underneath.

Why is that? As in the other screenshot I want to procedurally make a bevelled cuboid shape using 5 primitives of a cuboid and then use the 6th upper primitive (by splitting) to build some other geometry.

I know I can do it using some workarounds but this is the most straightforward way of doing it for me, and it works in Blender.

I'm using Houdini 19.5.435.

Thank you. It's good to know some more workarounds than I thought of.

Maybe the shape of the bevelled points is caused by the same reason why subdividing a cube doesn't result in a perfect sphere, I don't know, I guess I'll just have to accept this fact.

For subdividing a box into a sphere, you can also use a ray sop to project it onto a sphere. You may be able to use ray for your scenario but it's probably quicker to just extrude-bevel-delete.

Konstantin Magnus demonstrated a method [procegen.konstantinmagnus.de] of getting more regularized quadspheres.

Thank you very much, everybody. You gave me even more useful knowledge than I suspected.
