Delcam's PowerMILL CAM software will accept models in STL format
directly (as well as IGES etc.). Clearly the accuracy and quality of the machine model
will depend on the tolerance and quality of the STL faceting. If a suitable tolerance has
been chosen in a decent CAD system the results obtained are perfectly acceptable.

If you visit Delcam's site and follow the PowerMILL link you will
see more information posted.

Delcam's DUCT software and the newly announced PowerSHAPE packages are both
appropriate for the modelling of organic, complex shapes with particular emphasis on
modelling for manufacture. Again you can find more details by visiting the web-site.
I understand that the site is being updated today with information on PowerSHAPE.

Finally, if you really do want to produce a NURBS surface over an STL model then Delcam's
CopyCAD software will allow you to do this, again more information on

I hope that this may be of some help.

Subject: Conversion--help, a little OT

Dear list,

Since the discussion about file conversion is going on I'm wondering if
someone has some experience they could share.

I work with a polygonal modeler. Its a mixed bag of different types of
objects. One can make nurbs objects which are meaningful to an iges file
for machining--this doesn't allow getting all the different types of
objects into an iges file--only objects made with nurbs.

Anyone got a pointer to a conversion utility or program that will
convert polygonal iges or DXF or STL files to nurbs information, iges
format for import into various popular cam packages?

Also, any pointers to CAD programs that are appropriate to organic
modeling (complex surfaces) that are solid, nurbs based modelers?

Thanks in advance!!
