Assembly is crashing in creo 7

Hi,

your assembly is corrupted. You have to repair it by yourself -OR- you can send it to PTC Support.

Hi,
from your description it sounds more like your assembly itself has a problem and not the Creo installation.
As a start you can check the messages at the bottom left of your Creo window and try to identify what Creo tries to do before the crash.
Also, you can try to open the assembly in 'Automatic' representation mode (which will load the graphics only) and then one by one switching the subassembies to 'Master' via Representations until you receive a crash. Repeat the same for the subassembly to identify the problematic part.

If you are using Windchill, this is sometimes related to workspace issues/corruption. Delete the workspace and create a new workspace and try again.

If you are working in on directory folders, make sure you have all the search paths.

Since the assy works on one computer, check if there is any difference in config.pro options. Some options greatly affect large assembly performance.

I also agree with @Constantin , using simplified reps usually helps me. I typically start with a rep that contains no items and then one by one or a few components at a time, add them back as master rep and see what crashes. If you have sub-assy's you can also open them before opening the assembly to see if the problem is in on of them.
