I think that's what @gozlikehell is trying to replicate.

that should be feasible to model in Assembly4: draw a sketch representing the axis of the swing-arm and also the axis of the gear-box output (suppose they on the same level, if not make 2 sketches), draw a sketch marking the vertical (or a datum axis maight also do), attach LCS_arm to the axis and the vertical, offset the LCS_arm from the vertical by some angle (that you place in the Variables), attach a sketch to LCS_arm, draw the triangle of the arm and especially the axis of the wheel (which will have a funny 3D movement), attach an LCS to the output vertex of the gear-box and pointing towards to edge vertex of the wheel axis (and a horizontal if necessary). Attach also of-course an LCS to the wheel axis.

Are you sure it's a pure movement in the XZ plane (XY → XZ ?) ? If the axis of the swing-arm is not at 90° from the car symmetry plane then it will not be.gozlikehell wrote: ↑Thu Jan 30, 2020 11:14 am I think I understand what I have to do to correct it to get a full suspension sweep through the XY plane without flipping.
