Possible regression of OCE, FreeCAD

mslonik's picture

Dear Forum,

Hopefully you wouldn't mind if I share with you here information about possible regression in OCE library. Details were described here: http://forum.freecadweb.org/viewtopic.php?f=3&t=14430. Shortly speaking, it was suggested that:

OCC version: 6.6.0 was working perfectly

OCC version: 6.7.1 doesn't work
OCC version: 6.9.1.oce-0.18-dev as well, doesn't work as expected

Kind regards, mslonik

Hello mslonik,I would like

Hello mslonik,

I would like to clarify several points, which should be considered if you really want to help improving Open CASCADE Technology.

First of all, this is OCCT development forum, not OCE - it is unlikely you'll have some feedback from OCE developers on this forum (and OCE releases are not supported by Open CASCADE). Moreover, this forum is for developers - it is reasonable to write here if you would like contributing to OCCT and would like to ask feedback for your ideas (OCCT users can communicate on http://www.opencascade.com/forums site).

The best way to report an issue - is to register mantis issue with appropriate description and steps to reproduce. Please note, that most OCCT developers are unfamiliar with FreeCAD, thus test case should be first extracted from FreeCAD and reproduced using tools available in OCCT - Draw Harness script (most convenient for developers), OCCT samples or C++ code:
http://tracker.dev.opencascade.org

If you are not familiar with developers tools - you can ask FreeCAD developers to prepare bug report.

Registered as #27221

Hello mslonik,

Thank you for reporting the problem! I confirm it is present in OCCT; the issue #27221 is registered for it.

For the future, please consider reporting problems in a way that could be checked using OCCT DRAW, as suggested by Kirill above. For the case of Boolean operation failure, we need to have at least its argument shapes saved in BREP format.
