Select an option from the Curves menu to create Bézier curves, composite curves, ellipses, spirals, helices or planar sections.
This creates a curve by joining user-specified points.
Bézier curves are parametric cubic curves. The portion of the curve between points is a span. Each span is defined by a start and end point, start and end tangent, and start and end magnitude. On creation, there is tangency continuity between spans.
Selecting the curve and then a point on the curve displays the point, tangent, and magnitude.
Editing the curve enables you to:
Move the start/end point:
Change the tangent direction:
Change the tangent magnitude:
