C3D freezes when selecting hatch object alone

[rkmcswain]

Been through all the standard debugging steps. Hardware acceleration on and off. No difference. Latest approved display drivers, check. Turned OFF the PROPS palette (per the Autodesk KB article), no difference. It's not DWG file related, we can recreate this in any DWG. And so on and so on. Seemingly started a month ago or so.

One oddity: If the user selects something else with the hatch at the same time, it does NOT freeze. Select the hatch alone and they have to kill the acad.exe process - it never recovers. CPU hangs @ 12.5% (one full core).

We are going to check another user's profile on the same PC next, but my question is has anyone else run across this and found a different solution than those in the KB article?

Have you tried the CONVERT command to convert old-style hatch patterns?  I occasionally see similar issues with old-style hatches.

Not sure this will help, but it is something to try.

Thanks @brian.strandberg - we tested another user's profile on this same PC and the problem was not present. So we went back to the user with the issue, and reset the profile (meaning the old way, delete the registry key(s) and the %appdata% folders) - to force C3D back to day 1 status, for this user, and this solved the issue.

I just wish I know WHERE the issue lies so we could just kill that one thing and not the whole profile.

That would be very difficult to track down. I wish I had some brilliant idea to help. I will keep it in the back of my head just in case.

Thanks for chiming in. I can't tell you how many problems we end up having to solve this way.  Surely the Autodesk programmers could fairly easily identify why such issues exist and provide a fix, without the user even knowing that something broke.

But I'm not holding my breath.

Might I ask if IT locks the R/W abilities to the registry? As all Autodesk software requires R/W and I'm seeing a push by IT to shut down what may be causing issues. (There doing their job, just not without all the facts)

[rkmcswain]

No. I've never heard of that. Almost any modern windows application needs R/W access to at least the HKCU portion of the registry. Who is (and how are they?) locking this down?
