Gentlemen:
As a Laser Applications Engineer for a Machine Tool Builder I have been priviledged to use a couple of different software packages. One being Metalsoft Fabriwin which has done vast improvements in Laser although its forte is punching, the other being Metamation's MetaCAM which is by far the best Laser software I have used which also supports 5-Axis Cutting, Rotary Axis Cutting, punching, 3-D modeling, Nesting (powerful common line cutting algorithm), Parametric Drawing for HVAC, etc. I have heard good things about Radan from a sotware engineer that has a seat of this product, so I guess it's worth a try. Another decent package that I was given a demo while I was at a Trade Show was Lantek.
Hope this tip helps and does not sound biased.
Regards,
