Hi there!

This is a simple problem but really hard to explain....

I'm trying to create something like a robot arm and need to link three
parts of it in a somewhat special way: 

A-B              A: arm 2              B: expandable hydraulic cyl.
B-C              C: arm 1              * : rotation axis 
C-A              

as a triangle...

      \    \       / / B                       
        \    \   / /                   
          \    \ ?? missing link
            \ * \
          C \ _ \  

I've linked A to B and A to C in CSG Unions but can't connect B and C
in the same way...  well - I just need to fix the loose end of B to C
so that it won't move away from it when A is moved...



Grateful for every hint!
