prjFile = prjPath + "/" + "NAD 1983 UTM Zone 10N.prj"
sr = arcpy.SpatialReference(prjFile)
for DF in MAP.ListDataFrames(MXD):
DF.spatialReference = sr
However, it looks like there is nothing similar to the arcpy.mapping module in 10 available in 9.3. I need to access the MXD file and then the dataframe(s) it contains, in order to change the coordinate system.
I could not find anything useful so far, although I assume that other people may have similar issues.
My question therefore, is there any (simple) workaround to this using Python (arcgisscripting) in ArcGIS 9.3?
