## Detailed Description

Describes an axis in 2D 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: Geom2d_AxisPlacement axes provide the same kind of "geometric" services as gp_Ax2d axes but have more complex data structures. The geometric objects provided by the Geom2d package use gp_Ax2d objects to include axes in their data structures, or to define an axis of symmetry or axis of rotation. Geom2d_AxisPlacement axes are used in a context where they can be shared by several objects contained inside a common data structure.
