Summary0001840: Fillet after thickness gives invalid geometry (upstream OCC Bug)
DescriptionPutting a fillet on the inside corner of a thickness box creates an invalid shape.
Steps To Reproducego to part workbench
make a cube 100 mm all over
run geometry checker - no errors
select the top face of the cube
use thickness to make +10 mm sides and bottom
run geometry checker - no error
Select one of the inside vertical edges
fillet it with 6 mm radius
run geometry checker - error is "bad orientation of sub shape"
delete the fillet and thickness
make a new thickness with -10 mm
run geometry checker - no error
select a vertical inside edge and fillet 6 mm radius
run geometry checker - no error
Additional InformationI am using:

OS: Ubuntu 12.04.5 LTS
Word size of OS: 32-bit
Word size of FreeCAD: 32-bit
Version: 0.15.4159 (Git)
Branch: master
Hash: fa3a2a0d3a7a0a619ab6323e236376bb43636e79
Python version: 2.7.3
Qt version: 4.8.1
Coin version: 3.1.3
OCC version: 6.7.1

so the problem seems to be caused by the positive thickness somehow, when the part "grows"

Hope this helps

Can someone bump the upstream bug ?

In occ 7.2 the error is slightly different: it now reports that the tolerance value is invalid

Still the same behaviour with 7.3
