Rigid body

I’m trying to make a rigid body - basically a square - out of rectangles. I’m very simply create four rectangles as about 100x20, placing them in an overlapping arrangement to make a square and welding them as physics bodies.

Dropping this “square” onto a static “platform” object causes the pieces to come apart, albeit briefly. To get round this I created a static anchor object, off-screen, converted the platform to a dynamic body and welded it to the anchor. This pretty much gets rid of the disjointing.

Does anyone have a more reliable method?

(I will update with code later.)
