This is the error message I'm getting:
Failure reason: Timeout
The file has exceeded the processing limit for an individual file on GrabCAD due to its size or complexity.
We have logged this issue for further study.
I have had that happen numerous times on different models.
Usually they are pretty extensive, and I assume the 3D viewer for the website can not handle all of the data, but I have never confirmed if that was the issue or not.
If it is a simplistic part, could you post the link here and see if I am able to open it.
