After deleting some rips and corner seams on my model, I can no longer create rips, unfolds, or refolds.  They all come up with the same message as shown in attached picture.  Any ideas?

I have already shut down and restarted.

Sounds as if a face got removed so you now have only a surface model.  But I do remember getting a message like this in the last few weeks, with a file someone posted on this forum, where the body was reported as a solid in the browser, but still gave this message when trying to apply a rip.  Seems as if it was somehow corrupted.

How did you delete these features? Did you use the Delete Face command?

Hi JD,

No delete face command used. 

It is definitely a solid with volume and mass.  It contains a derived part but do not think that has anything to do with it. Interesting that somebody else had a similar issue.  I have even tried deleting everything all the way up to the derived part and recreating the extrusion, shell, and then ripping but same error.

-Must be corrupted somehow.

I will probably have to create a new part from scratch.
