|Summary||0032241: Mesh - wrong shading display of thrusections [regression since OCCT 7.4.0]|
|Description||I gentlemen, just after moving to OCC 7.5 I got this problem.|
This was working good with OCC 7.3.0
I do not know if the problem exists in 7.4.0
I tried to change deflection angle before building my shape etc... without success.
I consider it is a blocking problem for me as I cannot update my software with this wrong visualisation.
Thanks in advance.

Thank you for reporting the issue.
This is a known problem and additional use case will help us a lot.
However, it is not planned for implementation in the nearest future.
We'll keep you informed.

Hello Oan, thanks for the info. If I understand well it should be solved in 7.6.0, so in next september.
I know I can rollback to the 7.3.0 but this mean I have many changes to apply to my code and I will have to redo that again in september.
Is there something I can do do (even if it is not a clean solution) to remove this problem in waiting for your correction ?
> If I understand well it should be solved in 7.6.0,
Jerome, the target version in Bugtracker indicates only preliminary planning (next release is set by default).
The actual planning is done based on available resources and priorities - so that bug can be shifted to the next release.

Hi kgv, ok it is clear for the first part of the question !
Let's go for the second part: Is there something I can do (even if it is not a clean solution) to remove this problem in waiting for your correction ?

as for the second part of your question, there could be several ways to keep your progress:
- you are welcome to join OCCT developers community and provide your patches for integration or keep your drafts upon OCCT code as the basis for further development and finalization by making commits to corresponding branches in OCCT repository, even if solution is incomplete, but fits your requirements. Please refer to https://dev.opencascade.org/get_involved [^] for additional details.
- you may want to rollback to OCCT 7.3.0 for a while, but keep your progress related to recent version of OCCT using separate branch in version control of your personal project, e.g. local git, svn, etc. until the issue is fixed and apply it afterwards;
- you also welcome to make a request for paid services using "Contact Us" form at https://www.opencascade.com [^] or https://dev.opencascade.org/webform/contact_us [^]
