After Rebuild: "Curve 30863 Does Not Exist. Referenced by Curve 30943." Causing Mesh Problems

After Rebuild: "Curve 30863 Does Not Exist. Referenced by Curve 30943." Causing Mesh Problems

After Rebuild: "Curve 30863 Does Not Exist. Referenced by Curve 30943." Causing Mesh Problems

I receive the following after rebuilding Femap Database:

CODE -->

Rebuild Model
Beginning Update of Database...
Curve 30863 Does Not Exist. Referenced by Curve 30943.
Curve 25046 Does Not Exist. Referenced by Curve 30944.
Curve 30862 Does Not Exist. Referenced by Curve 30944.
Database Update Completed. Errors Found. 

I did a lot of geometry editing, so the messages don't surprise me. I am running into a problem with meshing and I think it is related. I can mesh successfully, but if I try to delete the mesh, it leaves several nodes undeleted. I have to do a file > rebuild and then re-delete those nodes.

How can I see/delete the references that the curves are making?

Thank you.

RE: After Rebuild: "Curve 30863 Does Not Exist. Referenced by Curve 30943." Causing Mesh Problems

Today´s release of FEMAP V11.2.2 is more robuts from the point of view of geometry Parasolid kernel, I suggest to update as soon as possible.
I remember in the past the error messge you mention: basically it appeared when you split the geometry repeatly. The use of FILE > REBUILD command in a regular basis is critical to detect any corruption of the geometry, I suggest to use it as much as possible.
Regarding the remedy, well, try to use the command DELETE > GEOMETRY > CURVE > SELECT ALL, this will delete all the orphan curves in your model (check that you don't have any "isolated" curve meshed with CBEAM elements!!). Also I remember that FEMAP in the past concentrated all corrupted surfaces in a point located in (0,0,0), check that the geometry exist using command DELETE > GEOMETRY > SURFACES and press the SHIFT key and open a selection window around the (0,0,0) and see if any entity is selected.

Also, you always can delete the "Curve 30863" using command DELETE > GEOMETRY > CURVE ...
