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:

• A3DIntervalData structure defines curve (1-dimensional) ranges.
• A3DDomainData structure defines surface (2-dimensional) ranges.
• A3DBoundingBoxData structure defines 3D ranges.

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).

Note

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