Contour Drawing of a Crowd: Overlap and Edge Continuity

Object Drawing Lessons

Contour drawing records the visible edge of a subject without shading or gesture. In a crowd, the challenge is overlap: where one figure passes in front of another, the contour line must stop, turn, or continue in a way that clearly shows which edge belongs to which body. This lesson treats contour as a single continuous line that describes the outer boundary of each visible form. You will practice deciding where edges meet, where they hide, and how to keep line weight consistent so overlaps read clearly. The convention used here is simple: a contour line follows the visible edge of a form and does not cross through a form that is in front. When two edges meet, the line may join smoothly or form a corner, but it must not create an ambiguous tangle. All numerical examples are hypothetical and should be adjusted to your actual paper and tools.

Defining the contour convention for overlapping figures

A contour line is a line that traces the visible boundary of a form. In a crowd, many boundaries are interrupted by other figures. The key rule is that a contour line belongs to the nearest visible edge at that point. If figure A stands in front of figure B, the line describing A's shoulder continues across B's torso, and B's contour stops where A's body hides it. This creates a clear visual hierarchy without shading.

Use one continuous line where possible, but allow breaks where an edge is genuinely hidden. A break is not a mistake; it is information about depth. Keep line weight even unless you deliberately vary it to show a nearer edge. For this lesson, use a single line weight so that overlap decisions are visible and checkable.

1. Identify the nearest figure in the crowd and trace its outer edge first.
2. Where that edge meets another figure, decide whether the line continues across the nearer form or stops at the hidden edge.
3. Mark a small gap only where an edge is truly hidden, not where you are unsure.
4. Check that no contour line crosses through a form that is in front.

Handling junctions between figures

Junctions occur where two visible edges meet. There are three common cases: a T-junction where one edge ends against another, a Y-junction where three edges meet, and a smooth join where two edges flow into one. In a crowd, T-junctions are most common: the nearer figure's edge cuts across the farther figure's edge. Draw the nearer edge as a continuous line and let the farther edge stop at it.

Avoid drawing both edges through the junction, which creates an X and makes the overlap ambiguous. If you accidentally create an X, decide which figure is in front and erase or redraw the farther line to stop at the nearer edge. Consistency matters more than perfect accuracy.

1. At each junction, name which figure is in front.
2. Draw the front figure's edge continuously through the junction.
3. Stop the back figure's edge at the front edge, leaving a clean T-junction.
4. Review the junction from a short distance to confirm the depth reads correctly.

Maintaining edge continuity across a crowd

Edge continuity means that a single figure's contour remains recognizable even when parts are hidden. If a figure's arm disappears behind another person, the visible contour should resume on the other side in a plausible position. Use simple checkable arithmetic to plan spacing: for example, if a hypothetical figure is 40 mm wide at the shoulders and the gap between two figures is 10 mm, the visible contour segment between them should be about 10 mm long. These numbers are examples only; measure your own drawing.

Keep the line direction consistent: if you are tracing clockwise around a figure, continue clockwise when the edge reappears. This helps the eye follow each figure through the crowd.

1. Trace each figure's visible contour in one direction.
2. When an edge is hidden, lift the pencil and resume at the next visible point in the same direction.
3. Check that resumed segments align with the hidden part's expected position.
4. Confirm that no two figures share an ambiguous merged outline.

Self-checking a crowd contour study

A finished contour study should let a viewer identify each figure and its depth order without shading. Use the checklist below to evaluate your drawing. The rubric allows valid alternatives: a line may join smoothly or form a corner, and a gap may be small or large, as long as the overlap reads clearly. There is no single correct contour, only a consistent and legible one.

1. Verify that every junction is a T or Y, not an X.
2. Check that each figure's visible contour is continuous in direction.
3. Confirm that hidden edges are marked by gaps, not by lines through front forms.
4. Ensure line weight is consistent or deliberately varied with a clear reason.

Worked example

A hypothetical crowd scene shows three figures: A stands in front, B is behind A to the left, and C is behind B to the right. A's shoulder overlaps B's torso, and B's arm overlaps C's leg. Describe the contour decisions at each junction.

Four practice exercises

Common mistakes

• Drawing both edges through a junction, creating an X. Decide which figure is in front and stop the back edge at the front edge.
• Leaving large gaps where an edge is actually visible. Resume the contour at the next visible point and check alignment with the hidden part.
• Merging two figures into one outline. Trace each figure separately and use a T-junction to separate them.
• Varying line weight randomly. Use one weight, or vary it only to show nearer edges consistently.

Self-check rubric

• All junctions are T or Y, with no X junctions.
• Each figure's visible contour is continuous in direction.
• Hidden edges are marked by gaps, not by lines through front forms.
• Line weight is consistent or deliberately varied with a clear reason.
• A viewer can identify each figure and its depth order without shading.
