IGeom3DCurve::Tangent

Description

This method allows you to get the tangent vector to a curve in a given parametrically defined point.

Syntax

Tangent = Tangent ( Parameter );

Input: (Double) Parameter

The parameter of a point in which the tangent will be defined.

Return: (Variant) Tangent

A variant that contains a double array of coordinates (x,y,z) of a tangent vector.

Note

All coordinates are given relative to the model's main UCS.

Some functionality may be dependent on the product package. Contact your Reseller if you require a license.
