"Flatten" command will move selected objects/parts of object to zero elevation (z value).

thanks a lot for your help.

You can also go into the properties dialog box and change the z component of the drawing to 0.  You might have to change the actual z coordinate beginning and end to 0.  Flatten is nice too.
