I purchased the HD Suite to design a significant remodel of my home. I was hoping to set up a base plan of the existing conditions of walls and finishes and then use the HD program to redraw walls and finishes and be able to view the changes on a single set of plans. I can't find any way of tracking the demo of existing and add of new walls? Is this program really only useful for "new construction" when calculating quantities and costs?
