Simple bug?

[togethearth]

Created 2 frames, one in the other. No joints, no hinge, nothing.

When I hit play the frame within the other wants to levitate above the other one.
See by yourself http://www.togethearth.com/files/simple_bug.skp

It was done with SU6 because SU7 crashes with SP on Mac (see another post about this problem for many of us).

You need to do every side of the frame as a "Box" and then group it together.

To set the state to "Box" rightclick on the Group --> SketchyPhysics --> Shape --> Box.

simple_bug.skp

That is your file but the frames to left is created by several "box"-groups.

Hope you understand!
