Analytical Curve

Create an analytical curve to be used either as a building block for constructing geometry or as a wire. Analytical curves are parametric definitions (in the parameter “t”) that define the path in three coordinate systems.

The derivatives of the expressions are required and need to exist over the entire path. If dividing the derivative by zero, the definition is not accepted. An alternative would be to calculate the points in the scripting environment and create a fitted spline.

On the Construct tab, in the Create Curve group, click the

Analytical Curve icon.
