Object Drawing Lessons
This lesson teaches a reliable way to draw a food truck by building it from a box body, adding wheel arches, placing a service window, and constructing an awning. You will use a simple convention: the truck is viewed from the side with a slight front angle, and all measurements are relative to the body length. The method is checkable with arithmetic, so you can verify proportions before adding details. No special tools are required beyond paper, pencil, and a ruler. The focus stays on the truck's structure, not on food items or background scenery.

Set the body box and wheel arches
Start with a horizontal rectangle for the box body. Choose a body length of 12 units and a height of 6 units; these are hypothetical example values you can scale to your paper. The body sits above the ground line, leaving space for wheels. Mark a ground line 1.5 units below the body's bottom edge. Place two wheel bottoms on the ground line, with centers one radius above it: the front wheel center at 3 units from the front and the rear wheel center at 9 units from the front, each with a wheel radius of 1.2 units. Draw the wheel arches as upward semicircular cutouts of radius 1.5 units whose centers lie on the body's bottom edge directly above each wheel center, so each arch rises 1.5 units into the body and its diameter lies along the bottom edge. The wheels sit within the arch openings and extend down to the ground line.
Check the arithmetic: the distance between wheel centers is 6 units, and each arch radius is 1.5 units, so the arches do not overlap. The arch tops sit 1.5 units above the body's bottom edge, leaving 4.5 units from the arch tops to the body top. Keep lines light so you can adjust.
- Draw a ground line and a 12 by 6 unit rectangle whose bottom edge is 1.5 units above the ground line.
- Mark wheel bottoms on the ground line, with centers one radius above it at 3 and 9 units from the front.
- Draw semicircular arches of radius 1.5 units centered on the body's bottom edge directly above each wheel center, cutting into the body.
- Draw wheel circles centered at the stated horizontal positions and one radius above the ground line; each circle should have its bottom point touching the ground line.
Place the service window
The service window is a rectangle on the side of the body. A practical convention is to center it between the wheel arches and set its width to 4 units and height to 2 units. Place its bottom edge 2 units above the body's bottom edge. The window top is then 2 units below the body top; the 0.5-unit gap plus the 1.5-unit awning exactly fill that 2-unit space, placing the awning top at the body top. The window's left edge sits 4 units from the front, and its right edge sits 8 units from the front, so it is centered over the 6-unit gap between wheel centers.
Verify: window width 4 units plus left margin 4 units plus right margin 4 units equals the 12-unit body length. The window height 2 units plus bottom margin 2 units plus top margin 2 units equals the 6-unit body height. These simple sums make the placement easy to check.
- Measure 4 units from the front along the body's bottom edge and mark the window's left edge.
- Measure 2 units up from the body's bottom edge and mark the window's bottom edge.
- Draw a 4 by 2 unit rectangle for the window.
- Add a thin frame line inside the rectangle to suggest the window opening.
Construct the awning
The awning attaches above the service window and projects outward. Use a simple trapezoid: the top edge is 5 units wide, the bottom edge is 6 units wide, and the height is 1.5 units. Place the awning's bottom edge 0.5 units above the window's top edge, centered on the window. This gives a slight overhang on each side. Draw the awning as a flat shape with a front edge and a side edge to suggest depth. A second valid convention is a scalloped awning; if you choose that, keep the same overall width and height and divide the bottom edge into equal segments.
Check: the awning bottom edge is 6 units wide, centered over the 4-unit window, so it overhangs 1 unit on each side. The awning height 1.5 units plus the 0.5-unit gap plus the window height 2 units plus the bottom margin 2 units equals 6 units, matching the body height. This confirms the vertical stack fits.
- Mark a point 0.5 units above the window's top edge and center the awning there.
- Draw the awning's bottom edge 6 units wide, centered on the window.
- Draw the top edge 5 units wide, centered above the bottom edge, and connect the sides to form a trapezoid.
- Add a front edge line and a short side line to show the awning's projection.
Refine and check the drawing
Once the main shapes are in place, darken the body outline, window frame, and awning edges. Keep the wheel arches and wheels simple. Use the arithmetic checks from each section to confirm proportions: body length 12 equals window width 4 plus two 4-unit margins; body height 6 equals bottom margin 2 plus window height 2 plus gap 0.5 plus awning height 1.5; awning overhang is 1 unit on each side. If any sum does not match, adjust the light lines before finalizing.
For a different awning shape, redraw the awning as a scalloped form while keeping the same 6-unit width and 1.5-unit height. For a different window position, move the window 1 unit toward the front and recheck that the new margins still sum to 12 units. These variations are valid as long as the arithmetic remains consistent.
- Darken the body, window, and awning outlines.
- Recheck the three arithmetic sums and adjust any line that is off.
- Optionally redraw the awning with a scalloped bottom edge, keeping the same width and height.
- Optionally shift the window 1 unit forward and verify the new margins sum to 12 units.
Worked example
Draw a food truck with a 10-unit body length, a 5-unit body height, wheel centers at 2.5 and 7.5 units from the front with 1.25-unit radius arches, a service window 3 units wide and 1.5 units high centered between the arches with a 1.5-unit bottom margin, and a trapezoid awning 4 units wide at the bottom, 3.5 units at the top, and 1 unit high, placed 0.5 units above the window.
Worked answer
Body: 10 by 5 rectangle. Wheel arches: centers at 2.5 and 7.5, radius 1.25, so distance between centers is 5 and arches do not overlap. Window: width 3, height 1.5, bottom margin 1.5, centered between arches; left margin 3.5, right margin 3.5, and 3.5+3+3.5=10. Vertical stack: bottom margin 1.5 + window 1.5 + gap 0.5 + awning 1 = 4.5, leaving 0.5 unit above the awning to reach the 5-unit body height. Awning: bottom 4 units wide, top 3.5 units wide, height 1 unit, centered over the 3-unit window, giving 0.5-unit overhang on each side.
Four practice exercises
Exercise 1
Draw a food truck with a 12-unit body length, 6-unit height, wheel centers at 3 and 9 units with 1.5-unit radius arches, a service window 4 units wide and 2 units high centered between the arches with a 2-unit bottom margin, and a trapezoid awning 6 units wide at the bottom, 5 units at the top, and 1.5 units high, placed 0.5 units above the window. Check all sums.
Show answer and check
Body 12 by 6. Arches at 3 and 9, radius 1.5, distance 6, no overlap. Window: left margin 4, width 4, right margin 4, sum 12. Vertical: bottom margin 2 + window 2 + gap 0.5 + awning 1.5 = 6, matching body height. Awning overhang 1 unit on each side.
Why: The window is centered because 4+4+4=12. The vertical stack sums to the body height, so the awning fits exactly at the top.
Check: Add the horizontal margins and window width; add the vertical margins, window height, gap, and awning height; confirm both equal the body dimensions.
Exercise 2
Draw a food truck with a 10-unit body length and 5-unit body height. Put the body bottom 1.5 units above the ground line. Place wheel bottoms on the ground line and centers 1.25 units above it, at x=2 and x=8; use arch cutouts of radius 1.25 centered on the body bottom at the same x-values. Add a service window 3 units wide and 1.5 units high, with its bottom 0.5 unit above the body bottom, and a scalloped awning 4 units wide and 1 unit high, 0.5 unit above the window. Center the window first, then try shifting it 1 unit toward the front. Check whether it overlaps the front arch and find the largest forward shift that clears the arch horizontally. Give the final margins and vertical stack.
Show answer and check
Body: 10 by 5 units. Wheel centers are at x=2 and x=8, y=1.25 above ground; each wheel has radius 1.25 and touches the ground. The front arch spans x=0.75 to 3.25 and rises 1.25 units above the body bottom. A centered 3-unit window starts at x=3.5; its vertical range is 0.5 to 2 units above the body bottom, so it clears the arch horizontally. A 1-unit forward shift moves it to x=2.5–5.5, which overlaps the front arch both horizontally (2.5–3.25) and vertically (0.5–1.25). The largest forward shift that clears the arch puts the left edge at x=3.25, so margins are 3.25 and 3.75 units. Vertical stack: bottom margin 0.5 + window 1.5 + awning gap 0.5 + awning 1 = 3.5 units, leaving 1.5 units above the awning within the 5-unit body.
Why: At the centered position, the window begins just to the right of the arch’s x-span. A 1-unit forward shift moves its left edge inside that span; because the window starts 0.5 unit above the body bottom and the arch rises to 1.25 units, their vertical ranges overlap too. Sliding it back until its left edge is 3.25 clears the arch; the left and right margins still sum with the 3-unit window to 10.
Check: Check the front arch x-range 0.75–3.25 and y-range 0–1.25 above the body bottom. Compare both ranges with the window at each position. For the final position, verify left margin 3.25 + width 3 + right margin 3.75 = 10 and vertical stack 0.5 + 1.5 + 0.5 + 1 + 1.5 = 5.
Exercise 3
Draw a food truck with a 14-unit body length, 7-unit height, wheel centers at 3.5 and 10.5 units with 1.75-unit radius arches, a service window 5 units wide and 2.5 units high centered between the arches with a 2-unit bottom margin, and a trapezoid awning 7 units wide at the bottom, 6 units at the top, and 2 units high, placed 0.5 units above the window. Check the vertical stack.
Show answer and check
Body 14 by 7. Arches at 3.5 and 10.5, radius 1.75, distance 7, no overlap. Window: left margin 4.5, width 5, right margin 4.5, sum 14. Vertical: bottom margin 2 + window 2.5 + gap 0.5 + awning 2 = 7, matching body height. Awning overhang 1 unit on each side.
Why: The horizontal margins are equal, so the window is centered. The vertical stack sums exactly to 7, so the awning reaches the top edge.
Check: Add 4.5+5+4.5 and 2+2.5+0.5+2; both should equal the body dimensions.
Exercise 4
Draw a food truck with an 8-unit body length, 4-unit height, wheel centers at 2 and 6 units with 1-unit radius arches, a service window 2 units wide and 1 unit high centered between the arches with a 1-unit bottom margin, and a scalloped awning 3 units wide and 0.75 units high placed 0.5 units above the window. Check whether the awning fits within the body height.
Show answer and check
Body 8 by 4. Arches at 2 and 6, radius 1, distance 4, no overlap. Window: left margin 3, width 2, right margin 3, sum 8. Vertical: bottom margin 1 + window 1 + gap 0.5 + awning 0.75 = 3.25, leaving 0.75 unit above the awning to reach the 4-unit body height. The awning fits.
Why: The vertical stack is less than the body height, so there is spare space above the awning, which is acceptable.
Check: Add the vertical components and compare with the body height; the sum should be less than or equal to the body height.
Common mistakes
- Making the service window too wide so it overlaps the wheel arches. Keep the window width at 4 units and center it between the wheel centers, leaving 4-unit margins on each side.
- Placing the awning directly on the window top with no gap. Leave a 0.5-unit gap between the window top and the awning bottom edge to separate the shapes.
- Drawing the awning narrower than the window. Make the awning bottom edge 6 units wide, which is 1 unit wider than the 4-unit window on each side.
- Forgetting to check that the vertical stack sums to the body height. Add the bottom margin, window height, gap, and awning height; they should equal 6 units.
Self-check rubric

- Service window is a rectangle centered between the wheel arches with margins that sum to the body length.
- Awning is a trapezoid or scalloped shape above the window with a visible gap and overhang on each side.
- Arithmetic checks for body length, body height, and awning overhang are correct.
- Lines are clean and the main shapes are distinguishable.
Questions and answers
Do I need to use the exact numbers given?
No. The numbers are hypothetical examples. You can scale them to your paper, but keep the same relative proportions and recheck the sums.
Can the awning be a different shape?
Yes. A scalloped awning is valid if it keeps the same overall width and height and the arithmetic still checks out.
Where should the service window go if I want it off-center?
You can shift it, but ensure the left margin plus window width plus right margin equals the body length, and the window does not overlap the wheel arches.
How do I know the drawing is correct?
Use the three arithmetic checks: body length, body height, and awning overhang. If the sums match, the proportions are consistent.
