I was trying to make a circle(not ellipse) with a NURBS curve function. I put the neccessary values like this
(order = 3, weighting factor [1 1/√2 1 1/√2 1 1/√2 1 1/√2 1], control points are red dots)
As you can see the image above, the (supposed to be) circle looks like a ellipse and I figured out that the length of the x axis of the grid square is longer than the y axis of it. How can I adjust this so I can make it looks like a circle?
