# Transformations Module

Creates and accesses transformation entities that can be applied to PRC entities containing geometry.

This module describes the transformation entities that can be applied to PRC entities containing geometry.

The abstract base entity for this module (`A3DMiscTransformation`) appears in structure members as a pointer that references either an `A3DMiscCartesianTransformation`or an `A3DMiscGeneralTransformation`entity. There are no functions to separately create or access an `A3DMiscTransformation`entity.

To determine the type of transformation entity referenced by an `A3DMiscTransformation`pointer, use the `A3DEntityGetType()`function.

Topics

- General 3D Transformation (using 4x4 transformation matrices)
- Cartesian Transformation
