Thank Kevin for replying so quickly. The problem I was having was that I was trying to create a rigid link between to points that were coincident. I believe that you have to have some significant distance between the two ends to create a beam (can't have zero length.) After resolving that, I noticed that if I was trying to connect points via a rigid length and these points were not part of the solid mesh, I would get another error. Do you know why that may be?
Without the files or at least some screen shots, it will be tough for anyone to give you decent replies.
So, upload your files if you can or post some screen shots including any errors and the feature tree.
And be sure to quote any messages you're not certain of.
Also, for better and more numerous replies, I suggest your edit your original post and add some appropriate tags:
This way people more knowledgable in simulation will see this and perhaps offer better help.
