3 Presenting Depth Use offsetting lines and different line weights around doors, windows, and cabinet faces

4 Shadows Shadows are cast when light is blocked from striking another surface Establish a light source so major features will not be hidden Project at 30°, 45°, and 60° Use a triangle to establish and maintain angles

5 Shadows Factors affecting layout of shadows –A vertical surface casts a shadow on the adjacent horizontal surface in the direction in which the light rays are traveling –A shadow on a plane, caused by a line parallel to the plane, forms a shadow line parallel to the line

6 Shadows

7 Projecting shadows onto an angled surface

8 Reflections Reflections are caused by water or glass Point to be projection will fall directly below that point and the depth will be equal to the distance that the point is above the water Large glass areas look dull unless rendered

9 Texture Draw roofing materials first with construction lines, then each shingle is drawn, and finally line quality is varied to show roughness Siding or paneling is drawn so all lines merge at a vanishing point –Vertical and horizontal lines of varying thickness is used

10 Entourage Entourage is the surroundings of a building It should not compete with the actual structure Keep entourage in proportion to the structure Plants are drawn freehand, traced, or applied with rub-ons

11 Entourage

12 Entourage People are either drawn in detail or outlined –Project people’s height to the vanishing points –Make sure people are in different poses Furniture helps provide a reference for scale and create a sense of realism Keep cars plain so they blend with the surroundings and do not detract from it

13 Entourage Content includes all the aspects of entourage Follow these guidelines –Use only necessary entourage to show location, scale, and usage of the structure –Use only enough detail to illustrate desired material –Never obscure structure with entourage

14 Two-Point Perspective Rendering Do several sketches to practice and determine the layout Trace perspective onto vellum Lay out foreground for entourage Lay out areas to be shaded Draw trees in foreground

15 Two-Point Perspective Rendering Draw people and cars, except on residential drawings Draw entourage to help tie the structure to the ground Render the foreground first then work to the background

16 Two-Point Perspective Rendering Draw major areas of shades and shadows Highlight areas in materials that cast shadows Letter the job title or owner’s name Use the same procedure for a one-point perspective drawing
