Lesson 12:Orthographic Drawings – Elevations

Dimensions

1. Interior Elevation
• Dimension heights of vertical elements including cabinetry, countertop, soffit, molding, wall panel, railing, grab bar, etc.
• Dimension heights of doors, windows, and wall openings from the finished floor lines to the tops of these objects.
• Dimension from finished floor lines to finished ceiling lines.
• Remember that interior elevations are mainly intended to show vertical heights of walls and other components related to them including doors, windows, millwork, and other important elements. Horizontal dimensions on interior elevations are to show additional information on spaces and elements that are not shown on the floor plan. Some professionals may prefer to place all horizontal dimensions on the elevations to provide more clarity and convenience for the builders. But it is better not to repeat dimensions in both places, since it increases likelihood of making errors when one drawing or the other is revised.
2. Exterior Elevations
• Label the important levels including the bottom of the footing, grade, finished floor line, finished ceiling line, and roof line with the elevation datum symbol.
• There are two methods to label these vertical dimensions in exterior elevation drawings. One is using a vertical dimension line with horizontal lines that extend out from features lettered parallel to it. Each extension indicates what the feature is with a note on it such as top plate, finished floor, etc.
• The other is giving the elevation height of each feature from the elevation established for the finished grade of the soil around the building. In this case, elevation datum symbol is associated with each extension line to indicate each elevation height. Vertical distances in exterior elevations typically start above the elevation of the bottom of the footing.
