Fusion 360
Intro
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
Modelling
You can model fully parametrically in fusion using simple sketches, extrudes, revolves, etc. There is a very large community of makers using this software and providing excellent tutorials for all of its functionality on youtube so if you don't have any experience at all with CAD I would start there.
Technical Drawings
Fusion has the ability to produce engineering drawings to both ASME & ISO standards; very useful functionality to have for free.
CAM
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.
CNC Mill
Using the milling tools it is possible to program the CNC Mill from Fusion. Once your toolpaths have been defined, export the G-Code by post processing using the built in Enhanced Machine Controller settings.
Tutorials
There are 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.
CNC Lathe
Chris Cain wrote up a bit of a how to guide back in 2016 over on the Denford Lathe page. There are some handy youtube videos documenting his spinning top Manufacture too.
3D Printer
The 3D Printer will also print parts from Fusion360 if they are exported in STL format. This menu can be accessed through File -> 3D Print.
Laser Cutter
You can export any sketch by right clicking it in the feature tree and pressing "Export DXF". This makes it possible to generate laser cutting paths in DXF format from 3D geometry. These can then be imported into Inkscape or directly into LaserCut 5.3.
For an example of how this can be used see the Les Plywood project.
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!!
