Is there a way to draw spirals easily? EasyPC has a special feature but can't find anything with CS

SCH or PCB? In SCH there is the Bezier, and lots of trail and error.

Draw it in CAD program, then import to CS from a DXF maybe?

It will have to be constructed from arc segments (or worse, many more line segments).

It's not clear how these are constructed, but they look good:

I don't remember if CS handles scripts........

Could you graph r=theta/a on polar coordinates for some value of a and then somehow export it to whatever format is useful?
