I have been using the electrical routing feature for some time now.  I recently installed SW 2012 and it appears a few things have changed.  I have my own wire size data file (xml file).  There is now a wizard in SW to aid in editing or creating files.  Whe I went into this file to edit my xml file it would only let me access the default wire file tha comes with SW.  How can i make SW allow me to access the other xml files?

Thanks...
