Summary	0000617: Error when fusing torus and tangent cylinder
Description	When perfoming a fuse operation on torus and cylinder, the resulting shape is incomplete, missing most of it's faces. Attached is a simple python script which reproduces the issue. Here is an example picture of the cylinder and torus as separate pieces on the left, and the union result on the right. http://i.imgur.com/SknDA.png Ubuntu Linux 11.10 64bit FreeCAD 0.13 5076 (Launchpad)

normandc 2012-03-03 18:09 manager ~0001702	I confirm this, same FreeCAD version and OS. I tried revolving a circle to get a torus, and padding a tangent cylinder, but the fuse of both shapes fails as well.

wmayer 2014-03-02 11:18 administrator ~0004347	Using OCC 6.6 or later this works now.

shoogen 2015-02-02 13:46 developer ~0005756	in occt 6.8 the BOP returns an invalid shape. The shell is reported to have Invalid MultiConnexity.
