Create Curves Toolbox

The Create Curves toolbox has tools that are used to draw curves of all types from B-splines to Helix curves.

All tools in a toolbox are not always visible by default. To see all tools, right-click in the toolbox and select Show All from the menu.

To Select in the Create Curves toolbox
Place a B-spline curve.

B-spline by Points
Create a B-spline curve that passes through a set of points while maintaining user-defined tangent directions at those points.

B-spline by Tangents
Place a composite curve, which can have line strings, arcs, or B├ęzier curves as components.

Composite Curve
Place or construct a complex chain of arcs that passes through a given set of points.

Interpolation by Arcs
Place a parabola, hyperbola, or partial ellipse.

Conic Curve
Place a clothoid or Archimedes or logarithmic spiral.

Spiral Curve
Place a helix in a 3D design.

Helix Curve
Note: B-spline curve and surface settings are set in the 3D and B-spline dialog, which is opened by selecting File > Settings > File > 3D and B-spline .
