I have a 2D mechanism modeling a simple pendulum with a shock/damper mounted at some moment arm from the pivot location. I was wondering if it was possible to add mass and moment of inertia properties in order to run a dynamic analysis of the pendulum. I tried using edit > mass properties then sececting the 'line' as the part and entering a mass and moment of inertia. However, I get an event error that says "The inertia is invalid at the center of gravity. Do you knwo if what I'm trying to do is even possible? I'm just trying to do this so I can quickly change geometries without fussing with solid models.
