Dimetric grid with two equal axes at 30° and a third at 60°.
A dimetric axonometric template in which two axes share a 30° inclination while the third tilts at 60°. The asymmetry foreshortens one face slightly, producing a more "cinematic" pictorial than isometric while still staying easy to measure with a parallel rule. Further reading: A practitioner reading list covers the standards lineage in more depth.
Conforms to the dimetric projection definitions in ISO 5456-3:1996 §5.3.
The 30/60 dimetric grid became the de facto standard for technical illustration in U.S. military maintenance manuals after MIL-STD-100A standardised it for "exploded view" service diagrams in the 1960s.
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.
