Lots of metaform confusion.
Bruce Mittelman (mittelb@iia.org) couldn't get metaform to work until
he discovered that "it was the Mod-Config file that was screwing up
Metaforming." Kiko (kiko@twics.com) correctly pointed out that
polygons have to be one-sided in order for metaform to work properly,
but wanted to know why, and said that MOD-config wasn't the problem.
MOD-config stores the Object Options settings, one of which is whether
new polygons will be one- or two-sided. The line in the file is either
"TwoSided 0" (no) or "TwoSided 1" (yes). There you go.
Metaform doesn't do what you expect when polygons are two-sided because
the two sides want to multiply in equal and opposite directions and end
up moving nowhere. Technical enough?
