# Creating a super elipses featurescript

Super elipses for reference: http://demonstrations.wolfram.com/VisualizingSuperellipses/

I'm trying to create a superelipses featurescript, but am having some trouble getting the shape to behave the way I want.

The two solutions I can think of are to 1) make geometry and then constrain it (so that the corner fillets are tangent to the rest of the arcs) in featurescript.

or 2) to make a sketch that will plot equations with a selected origin.

"The superellipse has parametric equations , ,

Any insight would be great.

for in the first quadrant (, ); multiplying by gives the equations for the curve in the other quadrants."

Any insight would be great.

Thanks
