![]() ![]() ![]() Other packages out there are TurboCad, RhinoCad, Solidworks, AutoCad. There are others but, when selecting a CAD program, you need to stick with a company that will be in business for a while as, it takes between 6 months to a year to become proficient with any particular package. It is full scale, professional stuff and is at the lower end of the mentioned price ranges. I happen to use and like a program called Geomagic/Alibre. CAD programs which have CNC file output capability can be expensive ranging from $1000 to $6000 with maintenance fees running between $300 to $1000 per year. Also, the free share-ware programs have the usual problem of not being supported and often are not very mature and have too many bugs. There are some free share-ware programs but many do not have the feature to export the file for use by a CAM program. Learning a CAD program takes a little time and practice. The software on the mill (often times, people use a program called Mach 3) then controls the mill to make the part. The G-Code is then loaded into the software on the mill. The typical workflow is to first design the part in a CAD program then, use the output of the CAD program as input to a CAM program to generate what is called G-code.
