poi_proj - Geometric procedure

Creates a point


Description

Creates a point in the XY-plane of the active coordinate system. In 2D this is the same as POI_FREE but in 3D if the Z-component of the position p specified is not zero then p is projected along the Z-axis onto the XY-plane before the point is created.
