Here's a bit of a tease of our upcoming update! 👀This part is the size of your thumb! 👍

Filleting a corner with 3 radii is non-trivial. No single ball radius can stay tangent to all faces at once, and the corner must be filled with a general n-sided blend, typically a Gregory patch that matches tangency along every bounding arc. Example: a 5 mm, 3 mm, and 2 mm corner has three fillet surfaces of different sizes meeting at mismatched heights, so the filler surface is a numerically-solved patch, not a primitive.

Here is a silly airport toy conversion, but it looks great so we decided to share!

Lower normal deviation (angle) produces more frequent, smaller flats/bands.

Have you checked your STL Export Quality? It comes down to surface deviation (distance) and normal deviation (angle). Curved regions benefit from more triangles and print smoother. Lower settings are fine on flat, prismatic parts; but on a cylinder, sphere, or fillet it leaves coarse facets the slicer reproduces as visible flats or banding.

Another STL to STEP example part! Use the Vertex Highlight and Edge Highlight tools to inspect before & after!
