Hello @Anonymous,

Thank you for posting in the Autodesk Community Forums. My name is Stephen, a Fabrication specialist, and I'll be happy to help you with this issue.

I understand you having some issues with you cursor freezing when touching a piping object. I would first suggest running through some of the Troubleshooting in This Article for this issue. It sounds like it could be AutoCAD based issue rather than Fabrication specific. 

Please let me know if the solutions in this article helps. If you find that your issue is resolved please select this post as "Accept As Solution". If not, let me know and we can continue to troubleshoot the issue. 

Thanks, 

Stephen St. Russell
