Re: Staad: Master/Slave Joints

Why should all frames have equal displacement in a given direction if their 
individual stiffnesses are different?  The rigid body diaphragm linking them 
will insure that the dimensions between them will remain invariant but should 
not preclude rotational effects on the rigid body which will lead to 
differing global translations for each frame.
