Lesson 11:Orthographic Drawings - Drawing Floor Plans

Techniques to draw floor plans

• The spaces (rooms) are best defined by drawing the walls black or heavily shaded.
• Exterior walls should be 8” – 12” thick, interior walls 4” – 8” thick.
• Wall materials are not shown, but doors, windows and any other openings are shown.
• All spaces should be labeled with fairly large lettering. Only the drawing title should be large, while all the other notes should be smaller.
• Some indication of size is needed for each space (either basic dimensions or square footage)
• Floor materials may be drawn to emphasize changes from one area to another or to emphasize circulation areas.
• Landscaping should be shown if it is part of the floor plan.
• Changes in floor elevation should be noted with stairs and ramps.
• Built in furniture and equipment should be shown and noted.
• Building parts (such as overhangs) above the cut line should be shown with hidden lines.
• A north arrow, and if applicable, section lines should be drawn.
• A drawing title and scale should be added.
• The orientation of the floor plan should match that of the site plan.
• If there is more than one floor plan, all of them should be oriented the same regardless of building shape.
