I would like to draw a superellipse but I am having trouble with the "Equation Driven Curve" tool.
I input the equation as so, as parametric: x=a*cos(t)^(2/n) and y=b*sin(t)^(2/n) where a, b and n is replaced with real numbers (I.E. a=2.3 b=4.2 n=3).
These inputs only gives me a quater of the curve, where I would like the whole ellipse.
I know I can just use the quater curve to make the whole, but is it not possible to get the whole curve at once?

The formula you are using is only defined for 0 > t > pi/2. If you need the whole curve in one formula you need the next formula (from wikipedia):
I don't think the sgn-funktion is available directly in sw. I would use the quarter-curve and either mirror the scetch or the feature.
PS I made a super-ellipse protecting steel plate for my fireplace using the mirror technique :-)
