Fusion 360
Fusion 360 is a 3d design tool for windows from Autodesk. It is a very full featured program and also has the ability to convert modeled parts to gcode which can be run on a CNC machine or to STL parts that can be printed on the 3d printer.
Installation
To get your Free copy go to the AutoDesk Web site
CNC machines
A number of the Hackspace CNC machines (Denford Lathe and the CNC Mill) will accept G-Code generated in Fusion 360. Use the CAM workspace to generate tool paths and post process using the Enhanced Machine Controller settings.
The 3d Printer will print parts from Fusion360 if they are exported in STL format.
Tutorials
There are also a number of youtube tutorial videos, the NYCCNC ones are rather good. The intro one is HERE do a google search for "NYCCNC fusion 360" to find lots more.
Recommendations
The best part is that Fusion 360 is available for FREE to students/Makers/hobbiests this is great value :-)
There is a lot of information at autodesk, and unusually most of the marketing hype about the capabilities of the program are all true !!.
If you want to make 3d parts this is probably the best software available at a reasonable price you will find!!
