Macro Shake Sketch

Description
Shake a sketch in order to discover its unconstrained parts. Enter edit mode for a sketch and launch the macro. The macro will add a random noise on all sketch points. The sketch is then solved, constrained parts will retain their position, free parts will move.

But be careful working on a copy of your file because the macro "dismantles all" to display and you may start over.
