Detailed Description

Defines a right-hand axis placement in 3D.

An axis placement is defined by a location point, a Z-direction and a reference direction (XRef).

The following image depicts an example of an axis placement:

Axis2Placement

The Z-direction defines a plane perpendicular to Z. Other directions are defined as follows:

• the Y-direction is defined as a cross-product of the Z-direction and the reference direction;
• the X-direction is defined as a cross-product of the Y-direction and the Z-direction.

X,Y,Z axes always define a right-hand axis placement.
