Airliners and warbirds, reduced to single-weight ink

Three-view reference

Plan, side and front, checked against each other

A three-view drawing gives the plan, side and front profiles of an aircraft on one sheet. Printable airliner plans are most often sold at 1:144 or 1:200 scale, and every one of them was built this way before a single outline was inked, because a single photograph cannot give all three profiles at a consistent scale.

What each view fixes

What the plan, side and front views check against each other, using the A320 as the example
View What it fixes A320 example
Plan (top-down) Overall length and wingspan 37.57 m long, 35.8 m span
Side Fuselage height and nose-to-tail curvature Cross-checked against the 37.57 m length so the fuselage does not stretch or shrink
Front Fuselage cross-section width and wing dihedral Cross-checked against the 35.8 m span so the wing taper matches the plan view

The standard three-view layout

The plan view sits across the top of the sheet. The front and side views sit below it, aligned so that a vertical guideline through the nose in the plan view also passes through the nose in the side view, and a horizontal guideline through the wingtip in the plan view lines up with the wingtip in the front view.

Three-view layout with plan on top and front and side views aligned below by guideline A plan view box spans the top of the sheet. Below it, a front view box and a side view box sit side by side, connected to the plan view by dashed vertical and horizontal alignment guides through the nose and wingtip.

Figure 1 Standard three-view drafting layout: plan across the top, side and front below it. The vertical nose guide and the horizontal wingtip guide, shown in the accent color, are what keep the length in the plan view consistent with the nose position in the side view and the span consistent with the wing position in the front view.

Building the reference

  1. Gather straight-on photos

    30–60 minutes

    Find or shoot side-on, top-down and head-on angles of the same aircraft variant, not a single three-quarter shot.

    Typical failure: using only a three-quarter photo, which foreshortens the fuselage and makes the plan view come out shorter than the real length.

  2. Look up the published dimensions

    A few minutes

    Record the aircraft’s overall length and wingspan from a manufacturer or reference source before drawing anything, for example 37.57 m and 35.8 m for the A320.

    Typical failure: skipping this step and scaling entirely off the photo, which carries whatever lens distortion the photo has.

  3. Draw the plan view first

    20–40 minutes

    Set the fuselage length and wingspan to the published dimensions, then draw the plan outline to match.

    Typical failure: drawing the plan view at a length that only matches the photo, so it disagrees with the side view once both are placed on the same sheet.

  4. Align the side and front views

    20–40 minutes

    Drop vertical and horizontal guidelines from the plan view’s nose and wingtip down to the side and front views, and draw both to meet those guides.

    Typical failure: drawing the side and front views independently, so the nose position and wing dihedral do not line up with the plan view underneath.

  5. Cross-check all three views

    10–15 minutes

    Measure length in the plan view, height in the side view and width in the front view against each other and against the published dimensions before moving to scale and paper.

    Typical failure: finding the mismatch only after inking has started, when correcting a view means redrawing panel lines that were already inked.

Questions about building a three-view

What if I cannot find a published three-view for the aircraft?

Build it from photos and published length and span figures directly, as in the steps above. The published dimensions are the anchor; the photos only supply shape detail within that anchor.

Do all three views need to be drawn at the same scale as the final plate?

Not necessarily during reference-building, but they must be at the same scale as each other. The conversion to the final print scale, such as 1:200 or 1:144, happens once the three views already agree.

How much time does this actually add to a plate?

For a single 1:200 airliner plate, building the three-view reference is the 30–60 minute photo stage plus roughly the first half of the 1–2 hour pencil layout stage that follows.
