Re: Scan to IGES

We use a product called Draftsman from Arbor Image Software. It has many tools
for cleaning up the scanned data while converting to IGES or many other
formats. However, I have to agree with Andy's statement. On any job I'm
getting paid for, I have always used the resulting iges geometry as a "tracing
template" over which I recreate the curves in the native CAD environment.
While retracing, you can adjust the geometry to match critical dimensions and
when you're finished, you have a parametrically editable model. For many parts,
it's easier to build the geometry from scratch and skip the scanning. wrote:
