Mechanism assembly - Ctrl+Alt+LMB not working anymore
Hi All! I'm just getting to grips with putting together mechanisms in Creo Parametric 3.0, and I'm trying to get a straight line linkage to work. When I modelled it I could simulate movement by Ctrl+Alt+LMB, but as soon as I put some relations in, the dragging function stopped working. Please see the attached screenshot.

Thanks for looking!
