Instruction making rant

[N. W. Perry]

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.

All I know of it is what's in the official File Format, which is, in its entirety:

Clear

Clears the screen

Format:
0 CLEAR

This command causes all previous drawn sub-files and line types to be cleared (erased). Any following line types are drawn as normal.

But it seems like it should work, as:

Code:

<some building steps>
0 BUFEXCHG_STORE
0 STEP
0 CLEAR
<some new parts>
0 BUFEXCHG_RETRIEVE
<building continues…>

But my other way seems to work fine, too (storing the empty model and retrieving it when isolating a sub-build).
