eVolve transformer family should be updated to add parameters that allow user to adjust transformer feet. Some transformer feet are set inwards from edge of transformer, and some are flush with transformer edge but protrude out past the transformer edges. This would be a beneficial for more accurate housekeeping pad layouts in tight electrical rooms as well as stacked transformer stand fabrication.
