The new ‘3D Curve from Axis and Gradient’ tool

You can use the 3D Curve from Axis and Gradient tool to create a three-dimensional B-spline from a planar axis and a planar gradient. You can define the direction and height of the resulting B-spline, which you can then use to model solids.

You can use the following elements for the axis and gradient: 2D elements, composite elements, 3D curves and edges of 3D elements. Each x-coordinate of the gradient must have a unique y-coordinate.

To create a preview of the 3D curve, first select the axis, which represents the 3D curve in plan, and then the gradient, which represents the real height of the 3D curve along the axis.
If the axis or gradient consists of several elements you cannot select with one click, you can use the Brackets.

You can change the start point of the axis or gradient by clicking the corresponding symbol in the preview. Finally, to create the 3D curve as a B-spline, define the height of the point where the 3D curve starts by clicking an existing point or entering the Reference height in the dialog line.
