Adobe Illustrator for Technical Drawing
Adobe Illustrator is a long-standing graphic design tool that works with many of the same basic principles as the 2D elements of most CAD packages. It's only natural, then, that it makes an ideal supplement for drawing 2D lines to be later turned into a 3D model, or even using it as a design tool in its own right for precise technical illustration or laser engraving images.
In addition, it contains tools for automatically making lines from existing bitmaps, making the transition from scanned image to 3D model even more efficient.
The Adobe Illustrator for Technical Drawing course is exclusive to H3-D and Holts Academy, taking many of the elements of the standard Illustrator course and tailoring them to a jewellery designer's needs.
