I am trying to merge two components in Apex using the Node Merge tool, one is made of shell elems and the other one is made of beams. The shell body has got RBE2s attached to it. When I merge the nodes the RBE2s disappear with no reason. I tried to replicate this behaviour with a smaller model but the RBEs are not cancelled in this case.
Is there any reason with RBEs should be deleted when other nodes are merged?
