yes... look at ode/test/test_boxstack.cpp
What you need to do, is attach multiple geoms to a single body.
Each geom is transformed by a transformgeom.
So to make a you object, you would create:
- 1 body
- 4 box geoms
- 4 trf geoms
This is much better than fixed joints, computes much faster,
less instability, more conventient to code, etc.
