Planometric - true plan rotated 30°, verticals stay vertical.
Planometric projection (sometimes called "axonometric plan") rotates the true floor plan by 30° or 45° and erects verticals straight up. The result is a measured 3D pictorial in which every plan dimension is true to scale - beloved of architects because the plan can be drafted normally and the building "extruded" up. Further reading: A practitioner reading list covers the standards lineage in more depth.
Planometric projection is a special case of axonometric described in ISO 5456-3:1996.
Planometric drawing was the signature technique of Auguste Choisy in his 1899 "Histoire de l'Architecture", and was later revived by James Stirling and the Cambridge school in the 1960s and 70s.
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.
