Summary

0030208: BRepFilletAPI_MakeFillet failure on small edge

Description

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.

Steps To Reproduce

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"
}

Notes
(0079774) msv (developer) 2018-10-08 10:47	Note that the edge 10 has small length 0.00252, which is much smaller than the the requested fillet radius 0.1.

(0079775) msv (developer) 2018-10-08 10:48	Fillet is built well with the radius 0.02, which is 10 times greater than the small edge length.

(0079776) msv (developer) 2018-10-08 10:49	Dear Julia, is it possible to make such fillet working?
