Point entities have an optional 50 group that determines the orientation of PDMODE images.
The group value is the negative of the Entity Coordinate Systems (ECS) angle of the UCS X axis in effect when the point was drawn.
The X-axis of the UCS in effect when the point was drawn is always parallel to the XY plane for the point's ECS, and the angle between the UCS X axis and the ECS X axis is a single 2D angle.
The value in group 50 is the angle from horizontal (the effective X-axis) to the ECS X axis.

Entity Coordinate Systems (ECS) are described ... somewhere else.
