Instead, you'd put the STORE command at the very top of the model, before anything's added. Then once you get to the sub-build, you'd first STORE the build so far into a second (B) buffer), then insert a RETRIEVE A command to bring back that first (empty) build state.
I never seen a CLEAR meta used with bufxchg, it isn't mentioned in MLCad documentation ether.
Is there any documentation available on its goal/usage, so I might add support for it in 1.7.
