there is a conditional formula in that attribute value, you can toggle this view via “=fx” button top right
I had to restrict some of the other parts, as they too were playing up
one can develop this further by using a counter (to act like a time line) , to do this, use animatecustom, so speed can be controlled
basically divide the action up, say 90 for each 90 deg turn, and 50 for the 27.5, each deg equates to a step in count for the 90 deg turn, and bit more for the lowering, 27.4/50, makes each step smaller in this case, hence longer to play. count from state 0 to 250
I didn’t worry about the ease in and out, made them zero, but try them out, or change the time to 6?
