Notion missing ? (by Pilou)
http://solvespace.com/pics/linkage-whitworth-solid.png

For this mecanism (or any others), does it possible to rotate it with infinite movements automatically like with an engine motor?
Seems I can only rotate with "hand" so some tiedous if want want make several turns! :)
Or maybe I miss something!

Use the Step dimension with an angle is maybe a solution but a little headache in some situation?
Or a trick is existing ?

Step dimension on an angle works, but only over 180 degrees without re-constraining against a different reference (since constraints on angles in SolveSpace are modulo 180 degrees, since they're actually on the dot product).

It's a bit of a hack, but you can draw an arc along the desired angle, constrain that arc length equal to a dummy line length, and step the line length. That gives a full revolution, which should be all you'd ever need (since the linkage is of course periodic over that).

Thx for the trick! :)
