This function is used to move a Category to another "slot" (or sequence number). When you move a Category to another slot, the assembly references also change.
WARNING!! When you move a Category, check Assemblies, and if necessary, change all items that used the old Category number to the new Category number. Otherwise, an "Invalid Item Number" error will occur when you try to take off an Assembly that uses the old Category number.
Highlight the Category you want to move, select Move Category. The Move a Category window displays, showing the available slots to where a Category can be moved.
Highlight the destination slot, OK (if you decide not to move the Category you can select Cancel). The Category is moved to the new slot, leaving the original slot empty.
