Positioning with CAD Surfaces

This knowledge base article will describe how to place an entity in the local coordinate system of an imported CAD surface. By default, imported CAD surfaces are defined in the global coordinate system. The result of this definition is that you cannot position an entity coincident to a CAD surface by simply choosing the CAD surface as the starting coordinate system of the entity since this would have the effect of locating the entity at the global origin. Rather, we need to use one of the options on the CAD import dialog to assign a local coordinate system to the imported CAD surfaces and use the FRED position/orientation operations to locate the entity properly.
