Description

Create a B-Spline is an icon button in the Sketcher geometries toolbar that groups tools to create a B-spline curve. Click on the down arrow to its right to expand the icons below it and select a tool.

Types of B-splines

Create B-Spline: Draws a B-Spline by its control points.
Create periodic B-Spline: Draws a periodic, closed B-Spline by its control points.
