“Easy,” you said. You needed an animated motion study within which a component needed to rotate 360 degrees, or some multiple thereof. “I’ll just set a key point at the desired ending position, and then rotate the component. SolidWorks’ transpositional animation will do just what I need.”

But it doesn’t seem to. In replaying your animation, the part doesn’t seem to have rotated at all. It’s not that the part didn’t move, per se – it did. Right back into the same position. SolidWorks will calculate the shortest distance between two key points. Which, in this case, is? None. In another example, a part that was to rotate 270 degrees has instead just rotated 90…in the wrong direction!

So, we discover a method that works just fine for linear translation is not so desirable for rotations beyond 180 degrees. What’s an animator to do?

We’re glad you asked.
