The [[Image:Sketcher_BSplineInsertKnot.svg|24px]] [[Sketcher_BSplineInsertKnot|Sketcher BSplineInsertKnot]] tool inserts a knot into a [[B-Splines|B-spline]]. If a knot already exists at the specified parameter its multiplicity is increased by one.


==Usage== <!--T:5-->
Insert a knot into an existing B-spline (See [[B-Splines|this page]] for more info about B-splines). If a knot already exists at the specified parameter, increases the multiplicity of that knot by one.

#* Use the menu {{MenuCommand|Sketch → Sketcher B-spline tools → [[File:Sketcher_BSplineInsertKnot.svg|24px]] Insert knot}}.
# The current position is marked with a small circle and its parameter value is indicated.
# Click to insert a knot, or click an existing knot to increase its multiplicity.
# This tool always runs in continue mode: optionally keep inserting knots and/or increasing multiplicity values.

Description

The Sketcher BSplineInsertKnot tool inserts a knot into a 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.
    • introduced in version 1.0: Right-click in the 3D view and select the Insert knot option from the context menu.
  3. Move the cursor to the desired location.
  4. The current position is marked with a small circle and its parameter value is indicated.
  5. Click to insert a knot, or click an existing knot to increase its multiplicity.
  6. This tool always runs in continue mode: optionally keep inserting knots and/or increasing multiplicity values.
  7. To finish, right-click or press Esc, or start geometry or constraint creation tool.
