What is the best way to overlay a revised field survey to show existing structure conflicts from a poor original survey and site new building changes. The only existing walls are from change in elevation as the remaining building has been demolished. The existing building was not properly located on the site and conflicts have developed. I believe an overlay would be best. but I need to be able to move overlay to properly align. The new and existing are not at same angle. Important to communicate with construction about changes.
