Reverse/Invert Lot Orientation

Is there a tool or recommended method to change how the vertex order is interpreted for determining lot orientation?  I have a large amount of building footprints and property lines representing property lots that I have imported as shapes from .dxf files.

All of the property line shapes are oriented  such that the buildings are extruded into the negative y axis (toward the center of the earth).  I suspect that all of the lots were drawn clockwise. 

The building footprints are a mix.  Some are drawn clockwise and counter-clockwise; therefore some buildings are extruded into the negative y and others are extruded into the positive y. 

I would like to avoid having to re-draw all of these building footprints and building lots in AutoCad. 

Thanks again,
