To apply: Select an isopoint on a curve, then choose Modify Curve Insert Knot from the Model menu.

To redisplay: Select the curve, click Selection on the Select panel, then click the corresponding Insert crv knot op icon.

Multiplicity

Specifies the continuity of the knot. For a cubic NURBS curve:

  • A multiplicity of 1 corresponds to C2 continuity (curvature).

  • A multiplicity of 2 corresponds to C1 continuity (tangency).

  • A multiplicity of 3 corresponds to C0 continuity (position).
