CNC G-Code can create arcs using either radius or I and J to represent the origin. The CAM program I use can create a circular pocket using a spiral path which turns out to be a series of short lines. I started thinking about how I'd draw a spiral in Alibre and stumbled a bit. The ideal is the end point of each arc becomes the starting point of the next with the arc progressing in steps every quadrant. But drawing this is very tedious although the idea was to try and recreate the g-code from a program. However it turns out the program also has a bug and start and end of the arc have a different radius so that didn't work.
Anyway, is there a way to draw a spiral in Alibre? It doesn't have to be a logarithmic spiral. In fact probably archimedes type.

Spiral, plane curve that, in general, winds around a point while moving ever farther from the point. Many kinds of spirals are known, the first dating from the days of ancient Greece. The curves are observed in nature, and human beings have used them in machines and in ornament, notably
