Most CAD packages have an STL conversion module that produces very high
quality STL output. Some of the lower end CAD packages have weak modules
and require a third party software to output good STL files. If we receive
an IGES file from a client we use Brockware (address below) to convert it
to STL. Brockware is a throughput program, so if it does not create a good
STL we will then patch/stitch it on our CAD stations or return it to the
client for repair, depending on the situation.
