scaling Curve from Equation

Hi

I created a curve from equation.

x = sin(t) + 2 * Sin(2*t)
y = cos(t) - 2 * cos(2*t)
z = -sin(3*t)

I tried Scale Model but it doesn't work on a curve from an equation.

 

Is it possible to scale the curve without modifying the equations?

 

Thanks

Select the curve then Copy Geometry and, under Options, select No Dependency.  This creates a copy of the curve that no longer references the original.  If you then scale the model, the original will stay the same and the copy will scale.

You have the equations defined. Just multiply each equation by a scalar value to "scale" them. If you explain the constraint of not modifying the equations that is probably useful to someone finding a workaround.

 

To double the size use scalar value of 2

i.e. for the X component: 2*(sin(t) + 2 * Sin(2*t))
