     It would probably be easier if you wrote out a DEF file.

     defOut myDesign.def

    Then in the DEF file, look for the COMPONENTS section. This will have each placed cell or block along with its coordinates and orientation. The coordinates will be in DB units, so check what your units are (from the tech LEF: usually 1000 or 2000) and divide the DEF coords by that to get microns.

     Hope that helps,
