Problems with moving components when simulating cerf cut

Hi, I am trying to simulate a cerf cut in plywood. I have made a series of components, linked with revolute joints. The component at the left end is grounded, and all components are in a contact set.

The model moves how it's supposed to, but dragging the components to make the part move is really difficult. Each time I click and drag, the model will only move a couple of millimeters. To achieve the result below, I had to click and drag the rightmost component about 40 times, each moving it a fraction of the way.

Am I doing something wrong here?

The reason for the performance breakdown is that you use contact sets and a relatively large number of components.

Contact sets are a real performance hog and it is not advisable to use these for a real final model.

OK, thanks.

 

If I don't use contact set or enable all contact, the parts just move into each other and all over the place. Is there a way around this?

No, not that I know off, other than using a "real" simulation in the simulation environment in Fusion 360.
