Unlike the apps from ArtCraft, this app is not recognized. I had to 'enable' it in security / "open anyways", then it worked. I'm trilled to experiment more, and see more. The MCP part is very interesting!
Fillets on three edges at a box corner with three different radii come out as one smooth 3-sided corner patch (tangent to the three cylinders within 0.01°, closed, 10 faces like Fusion). Fusion builds a 6-sided setback patch there instead. Our volume differs from Fusion's by: radii (A,B,C) Fusion mm³ ours mm³ delta (2,3,3) 7900.664 7908.921 +0.105% (2,3,4) 7867.820 7880.464 +0.161% (1,2,3) 7937.490 7941.503 +0.051% (3,3,1) 7914.849 7921.270 +0.081% (2,3,6) 7794.490 7798.774 +0.055% Equal radii (a sphere) and (r, r, R) (a torus) match within 0.006%. The data is in solvecraft-tools/corner_cases/ (local, Fusion-produced, never commit): setback_cases.json and case3_patch.json (patch vertices, loop edges, NURBS data). It covers a 20 mm box with A = edge x=20,z=20, B = y=0,z=20, C = x=20,y=0 at the corner (20,0,20). Fitted rule (fits all four 6-sided cases). S = ra + rb + rc. The two larger rounds end S/3 + (the other larger radius) from the corner. On the face between
About half of randomly generated designs evaluate without a kernel error. Every failing seed is a reproducible bug; the fuzzer reports the failing feature and seed.
Constant, chord and two-ended variable-radius fillets work, and so do corners where rounds of different radii meet (crease) and three rounds at a vertex (corner patch). Missing: Fusion's Setback corner type, and variable radius with radii at points along the edge.
