Quote - Didn't test the stacking enough.  I didn't consider that the translation dials use the global axes, not the local axes.  So that version of the script I just posted will only stack on Y, not on X, Z, or an arbitrary axis.  The attached shows what happens when you try to stack along some other axis.

I'll see what I can do to correct this.  Some simple vector math and the plane normal should do it....

I'll keep this version, one man's bug is another man's feature!

Quote - The tricky part, for me, would be creating the .cr2.  Can you supply some kind of template .cr2, containing only the basic information for a chain?  I could work from that to try to create something which might work out.

OK, I'll do a cr2. It may be too big to post in the thread, so can you IM me with an email address to send it to? When you say "containing only the basic information for a chain?" could you elaborate a bit on what you mean by that? Do you mean a skeleton with only the bits that would change with each link?
