Two vanishing points on a wide horizon - the building-corner view.
Two vanishing points sit on opposite ends of a wide horizon, well outside the printed frame so that the receding bundles of lines stay shallow and natural. This is the standard scaffold for any view that catches a building on its corner - exterior elevations from the street, urban-design vignettes, even product packaging on a shelf. Further reading: A practitioner reading list covers the standards lineage in more depth.
Vanishing-point geometry follows the construction rules in "Architectural Drawing" (Francis D. K. Ching).
Two-point perspective was demonstrated by Leon Battista Alberti in his 1435 treatise "De Pictura" and remained the dominant convention for architectural rendering until digital tools made arbitrary projections trivial.
Every variant on this page is delivered as a vector SVG with physical millimetre dimensions baked into the file, so a compliant printer driver will reproduce it at exact 1:1 scale by default. Choose the sheet size that matches your printer tray, set scaling to 100 % (never "fit to page"), and verify with the calibration check on our how-to-print guide. Buyer's guide: Comparing the major architectural scale rulers can help you pick the right physical scale rule to use over the printed grid.
