Object Drawing Lessons

This lesson teaches a reliable way to draw a WW1 biplane in side view. You will set a baseline, place two parallel wings, add vertical struts at consistent spacing, and position the cockpit between the wings. The method uses simple arithmetic and a defined drawing convention so you can check your work. All measurements are hypothetical examples; measure your own paper and tools. The focus is biplane-specific: wing stacking, strut placement, and cockpit layout. Modern aircraft, jets, and airport scenes are outside this lesson.

Set the baseline and wing stack

Start with a horizontal baseline across the middle of your paper. This line represents the lower wing's centerline in side view. Decide a wing gap: the vertical distance between the lower and upper wing centerlines. For example, if your paper is 20 cm tall, a hypothetical gap of 4 cm keeps both wings visible. Mark the upper wing centerline 4 cm above the baseline using a ruler.

Draw the lower wing as a thin horizontal shape centered on the baseline. Its chord (front-to-back depth) might be 6 cm in this example. Draw the upper wing directly above it with the same chord and the same front and back positions. Alignment matters: the leading edges should line up vertically, and the trailing edges should line up vertically. Use light guide lines to confirm alignment before darkening.

  1. Draw a horizontal baseline and label it lower wing centerline.
  2. Mark a point 4 cm above the baseline for the upper wing centerline.
  3. Draw the lower wing as a thin horizontal shape, 6 cm chord, centered on the baseline.
  4. Draw the upper wing with the same chord directly above, aligning leading and trailing edges.
  5. Check that both wings are parallel and that the gap is consistent along their length.

Place struts with even spacing

Struts are vertical or slightly angled connectors between the wings. In side view, show them as narrow rectangles or lines. Choose a strut spacing along the wing chord. If the chord is 6 cm, a hypothetical layout of four struts at equal spacing uses centers at 1.2 cm, 2.4 cm, 3.6 cm, and 4.8 cm from the leading edge; this creates five equal 1.2 cm gaps between the leading edge, the struts, and the trailing edge, keeping every strut inside the wing outline. Mark these positions on both wing centerlines so the struts connect matching points.

Draw each strut from the lower wing to the upper wing. Keep the strut width small, for example 0.5 cm, and keep all struts the same width. If you angle the struts, angle them consistently. Check that each strut starts and ends at the same chord position on both wings. Even spacing and matching endpoints make the biplane read correctly. When checking clearance near the cockpit, remember that a strut centered at 2.4 cm with 0.5 cm width occupies 2.15–2.65 cm, and one centered at 3.6 cm occupies 3.35–3.85 cm.

  1. Mark four chord positions at 1.2 cm, 2.4 cm, 3.6 cm, and 4.8 cm from the leading edge.
  2. Transfer the same marks to the upper wing centerline.
  3. Draw a narrow strut connecting each pair of marks.
  4. Keep strut width consistent, for example 0.5 cm.
  5. Check that struts are parallel or consistently angled and that endpoints match.

Lay out the cockpit and fuselage

The cockpit sits on the fuselage between the wings. In side view, place the cockpit opening between the mid-front and mid-rear struts. Draw a short fuselage body connecting the wings, with a rounded nose at the front and a tail section at the back. The cockpit opening can be a simple U-shape or a small rectangle with a raised rim.

Keep the cockpit proportional to the wing gap. If the gap is 4 cm, a cockpit opening 0.6 cm wide and 1 cm deep is a reasonable hypothetical example. With struts centered at 2.4 cm and 3.6 cm and 0.5 cm wide, a cockpit centered at 3.0 cm spans 2.7–3.3 cm, leaving 0.05 cm clearance to each strut edge at 2.65 cm and 3.35 cm. Check that the cockpit does not overlap the struts and that it sits on the fuselage centerline. Add a simple tailplane and fin at the rear, aligned with the fuselage.

  1. Draw the fuselage as a horizontal shape between the wings.
  2. Mark the cockpit position between the mid-front and mid-rear struts.
  3. Draw the cockpit opening as a U-shape or small rectangle with a rim.
  4. Add a tailplane and fin aligned with the fuselage.
  5. Check that the cockpit is clear of struts and centered on the fuselage.

Refine and self-check

Darken the final lines and erase guide marks. Label the upper wing, lower wing, struts, and cockpit so the biplane-specific parts are easy to identify. Letter styles vary, so accept any readable style; the labels only need to point clearly to the correct parts.

A simple rubric helps: wings parallel and aligned, struts evenly spaced and matching endpoints, cockpit between the wings and clear of struts, and overall proportions consistent with your chosen gap and chord. Valid alternatives include slightly angled struts or a rounded cockpit rim, as long as spacing and alignment remain checkable.

  1. Erase guide lines and darken final outlines.
  2. Measure wing gap and chord to confirm consistency.
  3. Measure strut spacing and width for evenness.
  4. Confirm cockpit position between the mid-front and mid-rear struts.
  5. Label the upper wing, lower wing, struts, and cockpit.

Worked example

Draw a side-view biplane on a 20 cm tall paper using a 4 cm wing gap and a 6 cm wing chord. Place four struts at 1.2 cm, 2.4 cm, 3.6 cm, and 4.8 cm from the leading edge. Place the cockpit between the mid-front and mid-rear struts.

Worked answer

Baseline at 10 cm from the top. Upper wing centerline at 6 cm from the top. Lower wing chord from 7 cm to 13 cm horizontally. Upper wing chord from 7 cm to 13 cm horizontally. Struts centered at 8.2 cm, 9.4 cm, 10.6 cm, and 11.8 cm from the left edge (1.2, 2.4, 3.6, and 4.8 cm from the leading edge at 7 cm), each 0.5 cm wide, all inside the wing outline. Cockpit opening centered at 10 cm from the left edge, 0.6 cm wide and 1 cm deep, sitting on the fuselage between the mid-front and mid-rear struts. With struts centered at 9.4 cm and 10.6 cm, the cockpit spans 9.7–10.3 cm, leaving 0.05 cm clearance to each strut edge at 9.65 cm and 10.35 cm.

Four practice exercises

Exercise 1

On a 15 cm tall paper, choose a 3 cm wing gap and a 5 cm chord. Mark the lower and upper wing centerlines and draw both wings aligned. Describe where the leading and trailing edges sit horizontally.

Show answer and check

Baseline at 7.5 cm from the top. Upper wing centerline at 4.5 cm from the top. Both wings span the same horizontal range, for example 5 cm to 10 cm from the left edge, so leading edges align at 5 cm and trailing edges at 10 cm.

Why: The gap is measured vertically from baseline to upper centerline. Alignment is checked by matching horizontal start and end positions.

Check: Measure the vertical distance between centerlines (3 cm) and confirm both wings start and end at the same horizontal marks.

Exercise 2

Using a 6 cm chord, place four struts at equal spacing. State the chord positions and the spacing interval. Draw the struts as 0.4 cm wide rectangles connecting matching points.

Show answer and check

Positions at 1.2 cm, 2.4 cm, 3.6 cm, and 4.8 cm from the leading edge. Spacing interval is 1.2 cm. Each strut is 0.4 cm wide and connects the same chord position on both wings.

Why: Equal spacing divides the chord into equal intervals. Four struts inside a 6 cm chord create five equal 1.2 cm intervals. Matching endpoints ensure vertical alignment.

Check: Measure each interval between strut centers; all should be 1.2 cm. Confirm each strut starts and ends at the same chord mark and stays inside the wing outline.

Exercise 3

Place a cockpit opening 0.6 cm wide and 0.8 cm deep between the mid-front and mid-rear struts on a biplane with struts at 1.2 cm, 2.4 cm, 3.6 cm, and 4.8 cm from the leading edge. Describe its horizontal position relative to the struts.

Show answer and check

The cockpit center sits between the 2.4 cm and 3.6 cm strut positions, for example centered at 3.0 cm from the leading edge. With 0.5 cm wide struts centered at 2.4 cm and 3.6 cm, the strut edges nearest the cockpit are at 2.65 cm and 3.35 cm. A cockpit 0.6 cm wide centered at 3.0 cm spans 2.7–3.3 cm, leaving 0.05 cm clearance to each strut edge, so it does not overlap either strut.

Why: The cockpit must be clear of struts and within the wing gap region. Centering between the mid-front and mid-rear struts satisfies both.

Check: Measure from the cockpit edges to the nearest struts; both clearances should be positive and roughly equal. With a 0.6 cm cockpit centered at 3.0 cm and 0.5 cm struts centered at 2.4 cm and 3.6 cm, each clearance should measure about 0.05 cm.

Exercise 4

A drawing has a 4 cm wing gap but the upper wing is shifted 1 cm forward. State one correction and one measurement to confirm the fix.

Show answer and check

Shift the upper wing back by 1 cm so leading and trailing edges align with the lower wing. Confirm by measuring the horizontal offset between leading edges; it should be 0 cm.

Why: Alignment requires matching horizontal positions. A 1 cm shift is corrected by an equal opposite shift.

Check: Use a vertical guide from the lower wing leading edge and measure the upper wing leading edge offset; it should read 0 cm.

Questions and answers

Do I need exact historical measurements?

No. Use hypothetical example values and measure your own paper. The goal is consistent proportions and checkable alignment.

Can struts be angled?

Yes, as long as they are consistently angled and connect matching chord positions on both wings.

How do I check wing alignment without a ruler?

Use a straight edge or fold a paper guide to compare leading and trailing edges vertically.

What if my cockpit looks too large?

Compare it to the wing gap; a cockpit roughly one-third of the gap width is a reasonable starting point.
