My first post on here, I'm looking for clarification on the description of the Fixed Hinge option in Simulation. Does the Fixed Hinge option mean that the hinge axis is fixed to the global coordinates and therefore cannot move at all? I'm working on a four-bar linkage system so there are a few moving hinge points in my system. Would the Fixed Hinge option prevent any of the hinge axes from translating and therefore be the incorrect way to model my connections? Is the Pin option (along with adding No Penetration) the way I should approach my model?
