Reproducible crash in Match

[GRSnyder]

I know very little about the Form environment, so it's likely that the operation below has no relationship to the intended use of the Match command. Nevertheless, it shouldn't cause a crash.

In the attached file, edit the form and run Modify -> Match. Attempt to match the top edge of the form surface to the smooth portion of the surface named Insert. That is, select four form edges and the central upper three edge segments as shown below. You will need to Command-select (on Mac) to select more than one edge segment from the surface.

When you release the Command key, Fusion 360 should crash.

Thanks for reporting this issue and attaching the f3d file.  This is hugely helpful.  I couldn't reproduce on a Windows machine but can reproduce on a mac.  I'll file a bug in our system and make sure it gets to the appropriate team for deeper investigation.

Very interesting! I was able to reproduce the issue both on a Mac-native copy of F360 and in a Windows 10 environment running under Parallels on that same Mac. Maybe it has something to do with the underlying GPU environment. 

Just for reference, I'm using a 2020 Mac Mini. MacOS system report attached.

Thanks for looking into this.
