My most-used extension (for 3D printing design). Effectively provides what should be default primitives. Quadsphere alone is indispensable -- this is just what it sounds like, a sphere composed entirely of quads (four-sided polygons).
great, but... same problem, only the round cube... (blender 4.2)
A very helpful addon, Only thing that bothers me is the Round Cube primitive. I wish it actually gives a Round cube by default.
Really help us to speed things up
