Not so much easier, just a different method. I'd rather use cartesian coordinates when explaining curves because most people model in a cartesian world. Conversion between cylindrical, spherical and cartesian is pretty simple. The good thing is that Pro/E can handle these 3 types, and if you don't know how to convert them, it's no big deal. If you wanted to use a cyclindrical type equation I would suggest the following, in keeping with the general form of the Archimedes equation. n=8 a=5 theta=t*n*360 r=a*theta "n" is number of turns "a" is distance between turns Having no "z" value defaults to z=0, which makes this cylindrical equation a polar equation. Defining any non-varying "z" value would do the same.
Thanks Mark! Thats the one I was looking for. Never thought of creating a sketch first.
Thank you everyone for input, sorry for the late reply.
