I am wondering if anyone has been able to set the angle of a crank in an assembly with a parameter driving the rotation. 
I have a dual crank mechanism that I would like to simulate in a few different positions. Angle 1 of crank relative to bearing housing, and angle 2 of crank 1 relative to crank 2. 

Is this possible with Discovery/Mechanical? Seems like it should be rather simple to setup but I cant seem to find a way to bring in those rotation parameters. 

I have tried using part transforms in Mechanical, but that only rotates one part at a time, and doesnt maintain the assembly constraints applied in Discovery. Ive also tried setting up revolute joints in Mechanical, but the positions of those joints are also not maintained during part transform. 

Any help is greatly appreciated.

Hi Brendan,

Part transform will help to modify the orientation in Mechanical. Can you see the parametrize option for the joint loads like rotation or may be setup an analysis with multiple steps indicating different orientations.
