Description

The Sketcher CreatePeriodicBSpline tool creates a periodic (closed) B-spline curve from control points. See this page for more information about B-splines.

Usage

See also: Drawing aids.

  1. There are several ways to invoke the tool:
    • Press the Periodic B-spline by control points button.
    • Select the Sketcher → Sketcher geometries → Create periodic B-spline option from the menu.
    • Use the keyboard shortcut: G then B, then P.
  2. For further steps see Sketcher CreateBSpline.

Notes

See Sketcher CreateBSpline.

Limitations
