LPub3D 2.4 apparantly has a replacement for buffer exchange called build modification, as explained here, but I haven't tried it out myself yet because I LPub 2.4 keeps crashing here (and LDCad doesn't have support for the new meta commands I assume).
Neat, I hadn't heard about this. It sounds fairly similar to my "FLOAT" idea, so I'm glad to see something along those lines being pursued.
Biggest difference I can see is that BUILD_MOD still relies on duplicate part refs, so any software that doesn't support the meta will still give the unwanted effects. With FLOAT, type 1 lines are only coded in their fixed position, so the fallback always shows the finished model, at least.
On the other hand, FLOAT is only imaginary and BUILD_MOD is real, so there's that. ;-)
