Hi Toby,

Try Modify...Element..Separate at nodes from Finite Elements form.

Thanks,

Sanjay.

Thanks Sanjay but the grids that I want to separate are actually shared by two MPC and not elements. Where is the "Modify->MPC->Separate at Nodes"? What I really want to do is just create a CBUSH with coincident nodes in one step. I want to just click on a single node and then create a CBUSH at that node with Patran automatically separating any elements or MPC's at that node. Is this possible?

You can separate MPCs wit Group-Transform-Move. Add one of the MPCs to a group, transform this group, create CBUSH, move group back
