Our site makes SLA parts for other plants in our corporate group. Occasionally,
we will get an IGES file from a customer to build an SLA. We first ask if their
system can output a .stl file. If they do not have this capability, and the
file is not watertight, we have used a service bureau to convert the file.

So far, they have not charged us anything, because they said it did not take
enough time to warrant sending us a bill. They have not told we which software
they use, but it sounds much easier than patching small holes in IGES files to
create a solid.

If you have to convert many IGES-STL files, I would contact one of these firms
and find out which software they use for this. I hope the service bureau firms
on this list will reply, because this software would be useful, if the cost is
not too high.

Hi all,
Can some users share their experience on the aspects of using some IGES
to STL software versus using a CAD software to do the same. I understand
that using a CAD software will involve first doing the IGES-IN then
either stitching/patching/offseting the surfaces into a solid and then
generating the STL-OUT. But what I would like to know from the users' is
how good each of these methods have been for them
Thanks in advance.

With Best Regards from Shreyas J Bakshi
