This .NET class wraps the AcDbPoint ObjectARX class. 

It represents the point entity within AutoCAD. A point entity has a position value to locate it in space. It also has a normal vector, which is used to determine its extrusion direction and to determine the plane on which to display the point's graphics if they are something other than a "." (the PDMODE system variable controls this display). The point entity has a thickness that is its "length" in the direction of its normal vector (that is, its extrusion length).
