wmayer 2011-11-10 18:00 administrator ~0001271	It seems that this is a bug in OCC. Since I didn't have any crashes with other data sets it is related to your data set. Maybe it's too complex for OCC. You can send it to werner.wm.mayer@gmx.de if you want.

cstrachan1 2011-11-11 08:23 reporter ~0001272	I have simplified the drawing to isolate what part causes the issue. To do this I grouped the connectors into one fusion leaving the enclosure in another. Trying to place the connector group on the drawing page results in the error: "BSpline curve : # Poles and degree mismatch". Nothing is drawn that I can see. Trying to place the enclosure on the drawing results in the segfault. I have attached a smaller file (900K) that contains just the enclosure and illustrates the segfault that the ticket was opened for. FreeCAD draws the assembly perfectly at all times when viewed in the normal model view pane.

wmayer 2011-11-17 09:35 administrator ~0001299	Rev 5144 implements a workaround for this issue. The projection still fails but at least the application doesn't crash anymore. This gives you the opportunity to slightly change the view projection direction. I built a debug version of OCC and there is an invalid vertex added to a compound.

~~Jriegel~~ 2011-11-21 09:06 administrator ~0001335	can reproduce on Windows. the projector call to OpenCasCade crashes badly. Its a bug for OCC

cstrachan1 2011-12-30 08:08 reporter ~0001522	behavior is the same with FreeCAD 0.13, Libs: 0.13R5359 and OCC 6.5.2

yorik 2012-05-05 18:42 administrator ~0002019	I think we can close this...
