Description

The Sketcher BSplineInsertKnot tool inserts a knot into an existing B-spline. If a knot already exists at the specified parameter, its multiplicity is increased by one.

Usage

  1. Select a B-spline.
  2. There are several ways to invoke the tool:
    • Press the Insert knot button.
    • Select the Sketch → Sketcher B-spline tools → Insert knot option from the menu.
  3. Move the cursor to the desired location where the new knot point is to be created, and click to insert the knot. The parametric value of the knot is displayed for reference.
  4. Optionally repeat the step above to create more knots.
  5. Right click or press Esc to exit knot insertion mode.
  6. Optionally use Increase knot multiplicity to increase the multiplicity of the knot(s).
