Thank you! I will eagerly await and try it.

MLCad is able to export every step, but it exports steps without information at
which line the previous step ends and were the next step begins.
For example when I export the CAR (still a great model :-) you get this:

Etcetera.
What you basicly want is some code after this line:
1 0 0 0 90 -1 0 0 0 1 0 0 0 -1 4315.DAT
to indicate that all previous parts including this one should have faded colors
and following parts are fully colored.
