Hello Wolfgang,
I'm not sure that the translation correct but I think I understand enough.
I've been using Rhino 3d (
http://www.rhino3d.com/) for about six months now and I am very happy with it. I also built my own cnc router about a one year ago. The router was based on drawings provided at
http://www.solsylva.com. It works reasonably well, however, just bought a new 40W CO2 laser from a company call Full Spectrum Engineering. Here's the link the the laser I bought:
http://www.fullspectrumengineering.com/ ... 2-40w.html. I got the super deluxe version. It's a little small (~370x240mm cutting area) but it's inexpensive and cuts well. I'm very, very happy with it!
The next thing I plan to do is build a laser based on the design at
http://buildlog.net/. I want my next laser to be at least 60W and have a cutting area of ~1200x600mm.
What's great about this laser is that you can basically "print" you parts out in wood and foam. There is no need to hold down parts like with the cnc router and there isn't any dust!
I can literally design parts and cut them out in seconds. I couldn't and wouldn't go back to cutting parts out by hand!

p.s. It's about a $1000 USD to get this unit drop shipped from China where they are actually built.
) etwas größeres Modell mit 4m Spannweite nach Plan zu bauen und überlege nun ob es sich lohnt zumindest die Rippen fräsen zu lassen. Nun hab ich allerdings im Netz wenig aufschlussreiches darüber gefunden wo man so etwas zu einem vernünftigen Preis machen lassen kann. Das CAD-Zeichnen (ggf. sogar in lesbaren Maschinencode umwandeln) ist weniger das Problem - das kann ich soweit schon selbst, nur an der "Hardware" mangelts dann
