|Insert Knots icon
Lets you add a knot point to a B-spline curve.
|Remove Knots icon
Lets you remove an existing knot point from a B-spline curve.
|| The available methods for inserting or removing knots are:
- By Point — (When Insert Knots icon is selected) Lets you insert a knot on a B-spline curve by picking a location on the curve.
- By Parameter — (When Insert Knots icon is selected) Lets you insert a knot at a location that is defined by the B-spline parameter value.
- Single — (When Remove Knots icon is selected) Lets you pick a knot location to remove from the curve. You can pick one at a time.
- By Tolerance — (When Remove Knots icon is selected) Lets you specify a tolerance. The tool will remove as many knots as possible, such that the deviation between the new and the original B-spline curves will not be greater than the input tolerance.
|| Used with the By Parameter method to specify the location on the curve where a new knot will be inserted.
|| Used to specify a value for the By Tolerance method.
|| If on, control points are turned on for the selected B-spline curve.
You can turn off control points with the Edit Control Points
