changing coordinate systems

[MikeHenson]

Greetings....I have received a mdx file from an outside source. It is in NAD 1983 UTM 15N. I would like to work in it using a state plane coordinate system. Can someone tell me how to change that? Thanks

You can make a tool for that:

If you browse to a tool in ArcToolbox, right-click the tool. That will open a batch version of the tool. Basically, it's a mini-spreadsheet so you can enter multiple input datasets, etc.

Don't bother using the actual "Batch Project" tool. It's buggy.
