Dear Lex,

Have a look at
and read what the "42" means (what do you say, HAL ?)

We use an interface for AP 214 "Core Data For Automotive Production".
It ranslates between Unigraphics and Pro-E without MAYOR problems.
(Just eats associativity in solid models and lettters in drawings).

The transfer of the solid - essential to RP - is no problem.

With kind regards

STEP has been some kind of a myth during the last years: it should
be there soon and then solve all geometry exchange problems.
I have never yet seen it work in practice, however one keeps hoping.
(we do use both IGES and STL)

Now the above makes by a bit suspicious:
what is STEP part 42 ?
Does this mean that there are now at least 42 versions, and if yes
are they compatible ?
Anybody out there having experience whether or not it does indeed work ?

Looking forward to some clarification: thanks in advance.
