I got a site plan covering larger extent of land prepared by a SketchUp. The plan consists of contours and roads marked. Though it looks like a flat (2D) drawing, from the plan view all the coordinates has (Z) value. Because the plan drawing is derived from a 3D contour plan created by another software used by SketchUp to AutoCAD. My exercise is to prepare (2D) plan drawings of buildings to be erected on site. After drawing individual building plans I found it difficult to place them on the site plan as it has lines with 3D coordinates. If I could bring all these (z) values to (0) value, I can utilize the same site plan to place my new objects. My requirement is only to place my drawings on a plan view and I do not want 3D lines of the site any more. I appreciate if you could guide me to over come this problem. Thank you.

You posted your question in the REVIT forum but your profile says you are using AutoCAD 2013.  Is that what you really intend to use....AutoCAD?If it is then you can use the FLATTEN command to bring all your geometry to an elevation of zero.
