Good freeware CAD programs?
Hey everyone,
I'm looking for a decent freeware CAD program that will let me make part outlines for laser cutting. The program needs to save as either .DWG or .DXF files so I can send them to the laser cutter. I need to be able to set sizes of holes, lengths, angles, all the sort of thing that CAD programs usually do. Any help would be great. Thanks, Fred |

Hey Fred,
Try DevCAD LE. You can download a trial version here: http://www.devcad.com/eng/default.htm and if you like it, you can buy the full featured version for 25 euros ($35). Stefano Durano (the designer) offers excellent support. There's a bunch of other programs available as well, including CAM, 3D CAD and airfoil drafting. Steve |

It's e machine shop 4 me!
I use the download from: http://www.emachineshop.com/
It is free, saves files as dxf which needs a little editing to get it into V carve Pro which I use to generate G code for my mach 3 controlled router. It has easy trim functions which I couldn't find in the program I bought-Design Cad 20. I tried Dev Cad too, with poor success. Try e machine shop, you pay nothing! |

Dassault Systems offers a free CAD system very similar to AutoCAD. I have only used it a little but it seems pretty powerful. Very good documentation and they even have a YouTube channel for training tutorials.
