Range Definitions

Detailed Description

group a3d_extent

Structures for defining range definitions for curves, surfaces, and 3D objects.

This module provides structures that define range definitions for geometric entities:

Range definitions specify the parts of geometric entities actually used in topological entities. These ranges are relative to a parameterization setting, which is specified in a curve’s parameterization data (A3DParameterizationData) or in a surface’s parameterization data (A3DUVParameterizationData).


Generaly, parameters of ranges must be ordered, for any kind of range.
