Summary0001983: Shape is not displayed as solid when cutting a cube with fillets by a border of the fillets
DescriptionMy use-case is to create a hollow box, all edges of which except 4 edges on the ground are rounded. It's hard to do that with a single makeFillet() call because I don't know which edges in the box.Edges are on the ground. As a quick solution I decided to create a bit higher box (target height + rounding radius), round all its edges and cut everything below z=rounding_radius plane by another box. But this doesn't seem to to give me a solid shape.
Steps To Reproduce
ext = ext.makeFillet(1.0, ext.Edges)
ext = Part.makeBox(10,10,10)
ext = ext.makeFillet(1.0, ext.Edges)
int = Part.makeBox(8, 8, 8)
int.translate(FreeCAD.Vector(1,1,1))

#this is displayed incorrectly, I think, because fillet radius is 1.0 that 
#corresponds to the cutBox height
cutBox = Part.makeBox(10,10,1)
Part.show(cube.cut(int).cut(cutBox))

#when I cut above fillet radius, everything is ok
cutBox = Part.makeBox(10,10,5)
Part.show(cube.cut(int).cut(cutBox))

Please offer the full script to reproduce this because the current Python code lacks of a couple of things.

Also provide the OCC version you are working with.

 I'm sorry, the script looks this way, the first line was from the previous experiment.

import Part
ext = Part.makeBox(10,10,10)
ext = ext.makeFillet(1.0, ext.Edges)
int = Part.makeBox(8, 8, 8)
int.translate(FreeCAD.Vector(1,1,1))

cutBox = Part.makeBox(10,10,1)
Part.show(ext.cut(int).cut(cutBoox))

OCC version seems to be 6.5.2
From /usr/include/oce/Standard_Version.hxx :

#define OCC_VERSION_MAJOR 6
#define OCC_VERSION_MINOR 5
#define OCC_VERSION_MAINTENANCE 2

 For
OS: Windows 7
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.15.4630 (Git)
Branch: master
Hash: 1b7c0e2a51bf4bffe5f345204c9c2bc6681e151d
Python version: 2.7.6
Qt version: 4.8.5
Coin version: 4.0.0a
OCC version: 6.6.0

The visual output looks correct but the geometry check also reports an error.

For
OS: Ubuntu 12.04.5 LTS
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.15.4627 (Git)

OCC version: 6.5.0

It visually looks broken (as in your screenshot) and the geometry check reports that the shells are not closed.

Upstream ticket has been resolved but I'm not sure in which OCCT version. @wmayer please advise

Can't say when it has been fixed. I tried it on Windows with FreeCAD 0.14, 0.15 and 0.16 and there the visual appearance looks good but the geometry checker reported an error. With 0.17 this error is gone now. occ version there is 7.0.

Under Ubuntu FreeCAD version is 0.17 and occ version 6.8.0 and there everything looks good, too.

So, issue can be considered as solved.
