I've wanted to test Sketcher as "2D kinematics simulator". I modelled car suspension with McPherson.
Model is very simply, eg. spring is symbolized as line without length constraint.
I attached file with my schematic car. Just open it (before this please delete zip extension) and start edit sketch. You can change:
car body angle - constraint 42
ground clearance - constraint 43
suspension geometry - other constraints
Have a fun!
