Summary	0030208: Modeling Algorithms - 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" }
Tags	No tags attached.

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

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

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