How to use it
Lines run in three directions — horizontal and at 60° and 120° — forming equilateral triangles that make cubes and 3D shapes easy to draw.
Print quality: the lines are true vector lines in the PDF, so they stay sharp on any printer at any zoom, and the file is tiny. Print at 100% (“Actual size”) so measurements stay exact to the millimetre. The file is created on your device.
Worked example
5 mm triangles on A4.
