Limicon Update - need "Equations" help
(OP)
After finding out that I need a Logarithmic Spiral (or nautilus) instead of a Limacon, I did some research and found the equation I need. This was confirmed on Mathcad. Problem is I've never used the Equations command before. I need to be able to put in a number for variables "a" and "b". It will solve the rest.
r(t)= a*b^(s*t), where a and b are >0, and range t=.1 to 20
Look up "Logarithmic spirals" for ref. @ this site.

Thanks.

eg. Consider a simple cylinder ... Dimensions would be applied to the Diameter & Length ... if the Length is always to be 3xDia the Equation would be "Length@Extrude1"="Dia@Sketch1"*3 then when the Diameter is changed, the Length will automatically adjust.
In other words you will have to draw the "Log spiral" first & then use Equations to adjust your variables relative to known data.

You cannot PLOT an equation in SW to get a curve or surface.
There may be some 3rd party apps or macros that have this ability, but not SW itself.
RE: Limicon Update - need "Equations" help
Actually thee are two choices here...
1. have the macro control solidworks to create the curve while its calcualting the points.
2. write the VB app to create a text file of x y z points, then reas that file into solidworks by using the INSERT/CURVE/ "Through xyz points"
Either way you will get the curve you desire.
