Could someone please help me reproject my local government model. right now it is in Illinois state plane east. I need it to be in Pennsylvania state plane North. every time I try to reproject it I get an error message about editing the schema. When I reproject the file I have to save the feature classes somewhere else. I can't copy and paste it or it messes up the schema/ relationship files. reprojecting the model seems like it should be simple enough thing to do I imagine everyone that downloaded the local govt. model would have to project the file to work with their data.
Could someone please help me?
