Our experience with Brock Rooney's IGES to STL conversion software has been excellent, as long as the surfaced IGES file is relatively clean.

Little extra work is required of the RP Center if the file is clean. In that case, the conversion typically works well on our default settings. For most files, the conversion takes 5 minutes or less. If the file has missing surfaces and/or gaps between surfaces, we often iterate through the software several times, changing parameters as we go.

We have run STL files created with this software through both our stereolithography and selective laser sintering equipment and have had no problems.

Hope all is well in Rochester.

Subject: igs to stl

I'd like to change the subject for a while if that's okay. How about
RP, we haven't talked about that lately. My question deals with the
Iges file to STL file conversion.

1)Could someone briefly explain how this process works and what its
limits are?

2)What systems are compatible and which are not?

I'm living in a somewhat isolated world here, mostly dealing with UG,
some ProE, and many .stl files. What I'm interested in knowing is what
additional work is required when an IGES file is supplied to a RP
Center and how the final part compares to one made from a CAD or STL
