The horizon is 115 mm down from the page top. The vanishing points are 75 mm to either side of the page center. For the reference construction, a 3D point (x, d, z) projects to X = page center + 75x/d and Y = 115 − 75(z − 1.4)/d. Here d is depth from the viewer and all model points have positive depth. This gives a single consistent level view for each study.
Extend a pair of edges from one horizontal family: they should meet at its marked VP. Test the other family separately. If one line goes to the other point, the block twists. A vertical line should not meet either VP. On a blank sheet, moving the VPs farther apart can make a new drawing less exaggerated, but you must rebuild all edge rays; changing only one ray will break the construction.

Setting Up Your Workspace
Work on the full printed sheet. Locate the horizontal horizon and the two vanishing points, VP-L and VP-R. The reference assumes a level view, which keeps vertical edges parallel. The vanishing points are printed outside the object but inside the sheet; preserve them while practicing. The student version supplies the front vertical and pale corner dots. Those dots fix this particular box, tower or pair of blocks. Complete that framework before inventing a new object. A straightedge helps separate a line-placement error from an unsteady stroke.
Drawing Vertical Edges
Identify the given front vertical edge and the back corner guide dots provided in the unfinished practice section. Using a straightedge, draw vertical lines upward and downward from these points. Remember that in this two-point perspective system, all vertical edges remain perfectly vertical regardless of their position. Do not tilt these lines toward the vanishing points. This strict adherence to verticality ensures that the box, tower, or neighboring blocks maintain their structural integrity and align correctly with the projected three-dimensional coordinates used to generate the reference images.
Converging Horizontal Lines
Group edges by their direction in the original block. The two horizontal model axes project toward VP-R and VP-L respectively; their edges keep that assignment throughout each block. Extend a reference edge lightly until it meets the horizon to identify its family. Keep that assignment for every parallel edge of the block. The third family stays vertical. The wireframe includes rear edges for construction practice; an opaque finished drawing can omit hidden edges after its geometry is established. The references show image geometry, not measured building dimensions.
Small checks that catch common errors
Watch for
Check instead
Tilting vertical edges toward the vanishing points.
Keep all vertical edges perfectly straight and perpendicular to the horizon line, as the camera level ensures no vertical convergence occurs in this two-point perspective setup.
Cropping out the vanishing points from the paper.
Retain the vanishing points on the full sheet even if they lie outside the desired crop area, as they are essential for accurately projecting the horizontal edge families.
Omitting hidden construction edges in the wireframe.
Include all hidden construction edges shown in the reference to fully understand the three-dimensional volume and ensure your completed wireframe matches the projected coordinate structure.
Print a test sheet before a full pack
Use the PDF that matches the paper loaded in your printer. Choose Actual size / 100% and turn off Fit, Shrink and browser headers. The SVG keeps millimeter dimensions, but an editor or browser can rescale it; the PDF is the simpler print path. Measure any calibration bars with a separate physical ruler when the exercise depends on printed size. A screen preview does not establish physical scale.
Packs combine the same individual pages; they are not extra different exercises. Print a student copy first and keep references nearby for review. Letter and A4 preserve the stated grid spacing or model definition while their surrounding white space can differ. Color is optional: the references also use line position, text or relative lightness to explain the result.
Useful answers
Do the vanishing points need to be on the visible drawing area?
No, the vanishing points may lie outside your desired crop. You must retain them on the full paper to accurately draw the converging horizontal lines for the box, tower, or neighboring blocks.
Are the reference images based on real building measurements?
No, the wireframes are projected from three-dimensional coordinates rather than measured building designs. The reference answer represents one possible completion based on these mathematical projections.
How do I know which vanishing point to use for a line?
Compare an edge with the guided reference and extend it to the horizon. One horizontal family goes to VP-L and the other to VP-R; repeat that assignment on all parallel block edges. Vertical edges stay vertical.

Start with a horizon line and two vanishing points placed on it, one left and one right. Draw the nearest vertical corner first. From its top and bottom, send lines to the left vanishing point and to the right vanishing point. Choose a depth along each side, then close the far verticals where those lines meet your chosen depth marks. The block should read as a corner facing you, with two visible side faces.
The check is structural, not stylistic. Every vertical edge must stay parallel to the first corner. Every edge running toward the left vanishing point must aim at that point, and every edge running toward the right must aim at the other. If one edge misses its vanishing point, the block looks twisted even when the outline seems plausible.
Draw a horizon line and mark two vanishing points on it, one left and one right.
Draw the nearest vertical corner, keeping it perpendicular to the horizon.
From the top and bottom of that corner, draw lines to the left vanishing point and to the right vanishing point.
Mark a depth on each side, then draw the far verticals between the matching projection lines.
Extend each horizontal edge mentally or with a straightedge to confirm it reaches the correct vanishing point.
Diagnose unnatural perspective with three tests
First, test the verticals. Hold a straightedge beside each vertical edge; any lean means the block will look unstable. Second, test convergence. Trace each receding edge back toward the horizon; edges from the same family should meet at one point, not scatter. Third, test the horizon relationship. Objects above the horizon show their undersides, objects below show their tops, and a block straddling the horizon may show both a top and a bottom face depending on how it crosses the horizon.
A common unnatural result comes from mixing two setups: vanishing points drawn in one place but projection lines aimed at another. Another comes from placing both vanishing points too close together, which makes the block look sharply distorted. Widening the separation usually produces a calmer, more believable corner.
Check every vertical edge against a straightedge.
Trace each receding edge to its vanishing point and note any that miss.
Confirm the block sits consistently above, below or across the horizon.
If the block looks distorted, move the vanishing points farther apart and rebuild.
A practical variation: two neighboring blocks
Once one block passes the checks, add a second block beside it using the same horizon and vanishing points. The second block must share the same two destinations for its horizontal edge families. Compare the two blocks: matching convergence confirms a consistent setup, while mismatched angles reveal an error in one block.
This variation also tests depth judgment. A block placed farther back should appear smaller along the same projection lines. If the farther block looks larger or its edges aim elsewhere, the construction has drifted from the shared geometry.
Keep the original horizon and both vanishing points unchanged.
Draw a second block offset from the first, using the same two vanishing points.
Compare corresponding edges between the blocks for consistent convergence.
Reduce the second block's apparent size as it moves farther from the viewer.
Try this example
Place a horizon line across the page. Mark a left vanishing point 12 cm left of centre and a right vanishing point 12 cm right of centre. Draw a nearest vertical corner 6 cm tall at centre. Build one corner block with a 3 cm depth on each side, then check convergence.
Show the worked explanation
The nearest vertical stays perpendicular to the horizon. From its top and bottom, lines to the left vanishing point form the left face; lines to the right vanishing point form the right face. Mark 3 cm along each side, draw the far verticals between matching projection lines, and close the block. Check: both verticals are parallel to the first, left-family edges meet the left vanishing point, right-family edges meet the right, and the block sits below the horizon so its top face is visible. Any edge that misses its vanishing point indicates a construction error, not a stylistic choice.
Common mistakes
Receding edges are drawn at a guessed angle instead of aiming at a vanishing point. Extend each receding edge with a straightedge to the horizon and confirm it meets the correct vanishing point; redraw any edge that misses.
Vertical edges lean slightly, making the block look unstable. Check each vertical against a straightedge held parallel to the paper edge and correct any tilt before adding detail.
Both vanishing points are placed so close that the block looks sharply distorted. Move the vanishing points farther apart along the horizon and rebuild the block from the nearest corner.

Questions before you start
How do I know which vanishing point an edge should aim at?
Edges running leftward across the drawing aim at the left vanishing point; edges running rightward aim at the right. Verticals aim at neither and stay parallel to the paper edge.
Why does my corner block look twisted even when the outline seems right?
Usually one receding edge misses its vanishing point or a vertical leans. Trace each edge to the horizon and check verticals with a straightedge.
Can I use the same two vanishing points for several blocks?
Yes. A shared horizon and shared vanishing points keep neighboring blocks consistent; each block's edges must still converge to those same points.
