Outlining can only be done with manual intervention, because there's no
final delimiter on the inlined code.  So the human has to select the code
to outline.

I *think* the matrix math can be reversed, but I'm not sure.  I don't know
if there is an inverse for matrix multiplication or not.  If not, each
transform is a 12-equation system of 12 variables, so it should be
solvable.

Note to [everyone who is not Sproaticus]: A single inlined reference can be
undone with cut and paste. But if a subfile is inlined more than once in a
single master file, cut and paste won't correctly undo all of the inlines.

(...) Whoops, I almost didn't read that. :-, But a cut and paste won't necessarily restore the origin of the sub-model, will it? My main reason for using sub-models is to place the origin in a weird spot, usually for rotation purposes. I agree that (...) (25 years ago, 3-Jun-99, to lugnet.cad.dev, lugnet.cad.dev.org.ldraw)
