I created a parabola with the “Curve Maker” extension, and then extruded around a circle to form a solid paraboloid. The paraboloid looks good, passes the “SolidInspector2” checks, and can be treated like a solid within SU.
Next I created a large cube, embedded the paraboloid within the cube (surfaces aligned), and subtracted to create a paraboloid bowl/indentation in a cube.
The problem is, the subtract tool left some complex holes (made of many non-planar edges) in the surface of the indentation. It does this with paraboloids with diameters of meters and hundreds of meters, so I don’t think it’s a scaling issue.
If the holes were simpler I would heal them by hand, as in this post: How to fill a hole left by a subtract, on a complex surface
But they are made of too many edges to manually triangulate.
I guess I’m looking for a tool to patch over holes in a surface by triangulation or some other healing technique. The only relevant extensions I can find are:
(Which claims to only work on faces anyway and doesn’t seem to do anything but hang the app.)
-another one I can’t link because new users can only post two links-
(Which is offered via a forum post whose download link seems to be gone.)
Any suggestions are appreciated!
