    Does anyone have a trick for sketching an "Equiangular Spiral"?

    You'll need to generate points (probably in Excel) using the polar
    equation r=a*e^(b*theta). You can then convert to Cartesion
    coordinates ( x=r*cos(theta), y=r*sin(theta), z=0) and input them as a
    curve in SW. Check the help file for the exact function to use and how
    to format the data. I believe it's just a tab-delimited listing of
    xyz coordinates.
