An excellent introduction is: http://softsolder.files.wordpress.com/2009/01/cnc-introduction-2011.pdf

Especially useful is CNC Quick Reference[1] --- a one-page .pdf w/ the essentials of cutting and G-Code.

The files area of the unofficial Shapeoko Facebook group has: https://www.facebook.com/download/2368776673448168/CNC%20Information%20Quick%20Reference%20Guide%206-7-2019.pdf CNC Information Quick Reference Guide 6-7-2019.pdf] [2]

There is an effort to get a Digital Fabrication area going on StackExchange, but it needs another two dozen or so questions to be up-voted.

	buildlog.net Build logs are the open source equivalent of the research notebook. You basically document the progress of a project, but it can be so much more. You can collaborate with others, get feedback, have people review your work. Often feedback can save you from mistakes already made by others. The site and forum are run by Barton Dring, whom we can thank for MakerSlide.

Clipart

Often, clip art will be done in stroked lines which are not suited to most CAM programs --- the solution is expanding the strokes and unioning them: https://community.carbide3d.com/t/converting-line-art-for-drawing/9493

SVG generators

Since the typical workflow makes use of scalable vector graphics (SVG), one can leverage tools which make these to produce designs or design elements for cutting:

• QR-Codes --- http://keremerkan.net/qr-code-and-2d-code-generator/
• Celtic knot work --- http://sourceforge.net/projects/knotter/
• Lithophanes --- http://3dp.rocks/lithophane/
• http://mandalacreator.com/
• https://inkscape.org/~fluent_user/%E2%98%85guilloche-pattern-extension

Digitizers

One can of course use a probe, or laser digitizer. A profile gauge is a useful option as well: https://en.wikipedia.org/wiki/Profile_gauge

http://fablab.ruc.dk/diy-digitizer/

Project Generators

Design into 3D is an effort to create a systematic set of project generators for CNC projects, documenting things well enough that one would be able to draw up traditional plans using pen and pencil and fabricate an instance of a project using hand tools.
