Linear Curve

2.0

Entity type is kA3DTypeCrvLine.

The canonical form is defined with the help of A3DMiscCartesianTransformationData, its origin (parameter 0) being the origin of the line and its vector X being the direction of the line. A3DParameterizationDataallows for reparameterization and trim.

Example of a line segment

In the above illustration, the line is restricted to [ t0 , t1 ]interval on the X vector of its Cartesian transformation.

Scale from A3DMiscCartesianTransformationDatamust be taken into account in previous evaluation’s algorithms.

Y vector from A3DMiscCartesianTransformationDatahas no particular meaning in this case and must be ignored.

Returns

A3D_SUCCESSon success, or an error code on failure
