I have an MXD with the results saved to it. I want to look at the parameters that were set for some of the tools externally, so I want to export the results.
Can this be done?
Right click on the tools you want to save and then either save them as Python snippets and paste them into a text file or select save as and save them as a results file. Or like KHibma says - if you save individual tools as a results file you can use ArcCatalog to add them back into ArcToolbox and see the parameters.
In the catalog window you could do a right click on the layer you want to review and access the metadata, there is an geoprocessing history section with detail (date and time, tool used and parameters) you could export to XML or copy/paste.
More detail on that and on how to view tool execution history
