Description

The Sketcher BSplinePolygon tool shows or hides the B-spline control polygon in all sketches.

The control polygon (green straight lines) connects the control points (marked with dark yellow weight circles).

Usage

There are several ways to invoke the tool:
- Press the Show/hide B-spline control polygon button.
- Select the Sketch → Sketcher visual → Show/hide B-spline information layer → Show/hide B-spline control polygon option from the menu.
