Summary0022727: Fillet not produces a result
DescriptionPost from the Forum - http://www.opencascade.org/org/forum/thread_21841/.
"1. I have used fillet making function "BRepFilletAPI_MakeFillet" for some time now and it seems that there are many instances it fails to create a fillet. Can anybody comment on the reliability of this function?
For example, I have attached a Brep file here and am unable to put a fillet in the common edge. Is there something wrong with my shape or is it a shortcoming of the makefillet function that I can't make a fillet there? How can I fix this?"

 ==> Bounding box is : DX=0.0545873 mm, DY=0.05459825 mm, DZ=0.0299319 mm.

"2. The model dimensions are actually in meters. It has not been converted to proper units when writing out the brep file. Basically DX would be 54.5873 mm actually. I have tried fillets with radius of 1 mm to 5 mm without success."

Shape is attached - toFillet.brep.
If try to scale the shape relative to center of gravity (x1000) =>
algorithm fails.

Additional information
and documentation updates		Modified entities:

ChFi3d_Builder_6.cxx

modified methods:

Standard_Boolean ChFi3d_Builder::CompleteData
(Handle(ChFiDS_SurfData)& Data,
 Blend_Function& Func,
 Handle(BRepBlend_Line)& lin,
 const Handle(Adaptor3d_HSurface)& S1,
 const Handle(Adaptor3d_HSurface)& S2,
 const TopAbs_Orientation Or1,
 const Standard_Boolean Gd1,
 const Standard_Boolean Gd2,
 const Standard_Boolean Gf1,
 const Standard_Boolean Gf2,
 const Standard_Boolean Reversed)

Now construction of BRepBlend_AppSurface is called in this method with two additional arguments: Degmax and Segmax.

 Dear BugMaster,
Workbench KAS:dev:mkv-22727-occt was created from SVN branch http://svn/svn/occt/branches/22727
(and mkv-22727-products from trunk) and compiled on Linux platform.

Test case for this bug is chl/934/D5. It is OK.

There are not regressions in mkv-22727-products regarding to KAS:dev:products-652-opt.

See results in /QADisk/occttests/results/KAS/dev/mkv-22727-products_17102011/lin
See reference results in /QADisk/occttests/results/KAS/dev/products-652-opt_23092011/lin
See test cases in /QADisk/occttests/tests/ED
N.B. In order to launch testing case you can make use the following instructions
