0030208: Modeling Algorithms - BRepFilletAPI_MakeFillet failure on small edge
Based on the limitations of the fillet algorithm, I'm not sure if BRepFilletAPI_MakeFillet should work on this case, but I've providing it in the hopes that the fillet algorithm can be improved.
restore shape.brep a
explode a e
if [catch {blend r a 0.1 a_2 0.1 a_3 0.1 a_9 0.1 a_10 0.1 a_11}] {
  puts "Error: building fillet failure"
}

Note that the edge 10 has small length 0.00252, which is much smaller than the the requested fillet radius 0.1.

Fillet is built well with the radius 0.02, which is 10 times greater than the small edge length.

Dear Julia, is it possible to make such fillet working?
