Chapter 6 In Class Drawing Project ­ Adding Dimensions to Floor Plan Layout Dimensions Let's now apply what you learned to the floor plan. Open the file and freeze all the layers except the walls and windows. If you really want to get fancy, put the wall solid hatch on its own (visible) layer and freeze the regular floor hatch layer so the carpeting and floors don't show. Next create a new layer for the dimensions, A-Dim. Finally set up the dimensions: Use Architectural units, Arial 6" font, leave the arrowheads as they are and change the fit to 15. Dimension the floor plan any way you want; what is shown below is a guide, but is not the only way.
