Elevations

Based on National CAD Standard 3.1 PDF pages 392-399

Elevations are projected from plans. Depending on the project size, section and window symbols may or may not be included: in general, they show up on plans for small projects; and on elevations for larger projects, but never on both. Column grid lines may be included for orientation, but without dimensions, and usually only at corners or discontinuities. Include vertical dimensions. Indicate materials and material edges, using hatching at edges if needed for clarification. use key plan with elevation symbols if key plans are used on plan sheets.

Show hidden items like lintels with dashed lines. Indicate sealant joints or other similar elements of the elevation.

All elevations are shown as projected; add more elevations for surfaces that are curved or angled with respect to the nominal north-south-east-west coordinate system. That is, the elevation for angled surfaces is drawn "looking" directly at the surface (line of sight perpendicular to the surface being drawn). For complex surfaces with multiple angles, draw an "unfolded" version, labeled as such on the plan. For complex curves, draw a "straightened curve" version, also labeled on the plan.

Show grade levels, with any "masonry ledges" or other foundation elements that are below grade indicated as dotted lines. Obtain grade elevations from spot elevations on site plan.

Do not include graphic embellishments such as people, cars, or shadows.

Show any "building identification graphics."

Interior elevations

Necessary for room like kitchens, or classrooms, or any other space where the wall/partition geometry is too complex to be summarized in a room finish schedule or partition type. Include: access panels, louvers, grilles (generally after discussion with mechanical/electrical consultants); changes in wall materials; required vertical dimensions (and horizontal, if not shown on plans).
