## Detailed Description

Describes an axis in 3D space. An axis is defined by:

• its origin, also termed the "Location point" of the axis,
• its unit vector, termed the "Direction" of the axis. Note: Geom_Axis1Placement axes provide the same kind of "geometric" services as gp_Ax1 axes but have more complex data structures. The geometric objects provided by the Geom package use gp_Ax1 objects to include axes in their data structures, or to define an axis of symmetry or axis of rotation. Geom_Axis1Placement axes are used in a context where they can be shared by several objects contained inside a common data structure.
