Boolean operation does not work with these objects - Why ? Or how would you do this ?


There’s just one face around, and can’t have that. It’s a severely non-planar n-gon. Curved surfaces need to be described with more geometry, just like a cylinder has more faces around than a cube.


There’s inconsistent amount of geometry around, while still having angles (top). The perimeter is described with too many vertices (bottom).

The file contains one example of making that with consistent round form and aligned structure for that form, by starting with a curve and then either

  • using the modifiers for the curve to get the round form, then converting to mesh and clean
  • or by converting to mesh, deforming it, and then applying modifiers and cleaning it

Simple deform modifier doesn’t merge the ends, so there’s at least that part that needs fixing. When converting curve to mesh, you want to adjust the resolution so it’s easier to deal with as a mesh. In this case remesh modifier will decide the resolution so it doesn’t matter as much.

There’s wrong terminology in the modeling subforum threads, and Andrew Price isn’t helping.

  • 3D objects have forms, we interpret and model forms, not shapes. A shape is 2D, and in a 3D object shape is its silhouette, which depends on its forms and the viewing angle
  • Just because AP says booleen and has a site called poliigon, there are neither in modeling. It’s boolean, and mesh surfaces are made out of polygons
  • Subdivision surface modifier name in Blender is “Subsurf” by default. That’s not a shorthand for subsurface like people seem to advice in other thread(s). The modifier affects the surface itself, not something below it like “subsurface” would indicate. Correct shorthand for subdivision surfaces is SubD surface, or SDS.

That’s not hate towards AP, although he definitely should know his terminology better, starting from the most basic mesh element that is a vertex, not vertice. More of a disappointment that comes from reading these threads and seeing booleen, poligon, indicating people are not critical enough towards the information they’re receiving. Yes, also question the information I’m giving.
