Assuming most elements of the plan are orthogonal, you can turn ORTHO on, draw parallel Lines or Rays perpendicularly from relevant points outward from the edges of the plan, and use them as projection for the horizontal position of things in the elevations. Draw floor-plane and/or ground-plane lines far enough outboard from the plan, as a basis to measure the heights of things from. The elevation off the bottom side of the plan will be upright, the one off the top side upside-down, and those off the sides turned 90 degrees, so you will need to rotate things once you get the basics established. You could instead do each side as the bottom edge, and rotate the plan appropriately for drawing each. If you have an outside wall that's angled, and want an elevation looking straight at it in a non-orthogonal direction, that would be the easier approach, although you could also change the angle that ORTHO works at, using the SNAPANG System Variable and aligning it with the angled face. As Dean said, this is all pretty much the same approach you would take with manual drafting.

Maybe my expectations of how this might work were inaccurate. At this point, I'm wondering how to to link the views so I can display the 3d model....so much to learn..
If you want them to be inter-related like that, and not be just the electronic equivalent of paper drawings, you should construct it as a 3D model, and then you can set up views to "look at" that model from any direction to get elevations [and even the plan view]. You can generate the 3D model out of the plan you already have, but don't "draft" the elevations. Revit and the Architectural add-ons to AutoCAD exist to make that easier, but it is possible [though more work] to do it in basic AutoCAD -- look into User Coordinate Systems, 3Dface for surface planes, and/or the various 3D Solid commands [Extrude, Slice, Union, Subtract, etc.]. It may not be very easy for a beginner, but it is doable.
