adding joints to parallellogram

[gertjanmeij]

In the model are the moving parts from a bicycle derailler for the parallel movement, when adding the 4th joint it gives a error message. How can joints be applied to any parallellogram?

When the 4th joint causes all to fail, check for alignment errors within the parts or Joint selected snap points, 

or you can cheat and make one a cylindrical Joint.

Might help....

Thanks... the alignment was difficult to find, but the cylindrical cheat works just fine.
Now it moves with 3 revolving and 1 cylindrical joints.
