Description[edit | edit source]

The Sketcher BSplineConvertToNURBS tool converts edges to B-splines.

Various objects before conversion.

The same objects after conversion to B-splines.

Usage[edit | edit source]

  1. Select one or more edges.
  2. There are several ways to invoke the tool:
    • Press the Geometry to B-Spline button.
    • Select the Sketch → B-Spline Tools → Geometry to B-Spline option from the menu.
  3. The edges are converted.

Notes[edit | edit source]

  • Make sure to have the B-spline degree, polygon, comb, multiplicity and/or weight visible, otherwise nothing seems to happen.
  • If you have converted straight lines you need to increase the degree of the created B-splines to make them "bendable".
  • The tool does not remove the internal geometry of conics. This has to be deleted manually.
