split to boolean fail

[dulouie]

The boolean feature has a wrong shape, look at the attached file.
booleanSplit_fail.zip

[dulouie]

And increasing the Extrusion plane length cause crash.

[realthunder]

The split failure is most likely an OCC problem. You can see that the split is not correct near the seam edge of the cylinder. You can work around this by split at a different angle, avoiding the seam edge.

I can't reproduce the crash reliably. I did fix a crash problem related to rendering. Not sure if this is the crash you experienced. Did you have any stack trace when it crashed?

At 153b298 increasing and decreasing the length of the extrusion multiple times i get this crash log.

Tried to run Gui::Application::initApplication() twice!

With up-to-date branch at a386a12 i get also a crash after some time of fiddling with the extrusion length.

Tried to run Gui::Application::initApplication() twice!
