Mechanism Question

Mechanism Question

I need help setting up the constraints for a mechanism, my experience is limited.

The mechanism consists of two separate assemblies.

Assembly One has a fixed part ‘A’ and a moving part ‘B’ which has a general mechanism constraint.

Assembly Two has a fixed part ‘D’ and a moving sub-assembly ‘C’ which has a general mechanism constraint.

In the top level mechanism Assembly Two is assembled first as default and then Assembly One is introduced as a general mechanism constraint.

I can only seem to achieve Fig 2 but need to show the mechanism as Fig 3.

Also when the mechanism is fully mated I need to show the two assemblies in their demated positions on separate drawings, whilst still maintaining the mated position in the top level mechanism drawing.

The config 'enable_advance_collision' is turned on and the 'Global Detection' is on in each assembly and the top level mechanism.

I have attached the CAD data.

Any help or advice would be greatly appreciated

I would be so tempted to simple add a servo motor and gear connections at a single level with user defined motion profiles for each element.

I have not used collision on any mechanism to date. I know it has limitations and the logic should be simple. However, I find motion profiles are also easy to manipulate.
