I would like to know if there is an easy way to move an
object on a plane surface.
Context: I create some toys for my children and I like to "assemble"
with SU the different parts to see the final result in a 3D view. That means
that at the end I have some blocks titled in a strange position.
To realize the toy, I need to draw a flat template on paper,
the paper is glued and with a jigsaw, I cut plywood. I’m wondering if there is
a plug-in or a best practice to move all the objects on a plan surface
(sometimes, when I move manually, the objects are not exactly “glue” to the plane surface).
