Practical uses

  • Geometry exercises
  • Tessellation design

Accurate printing

PDF and SVG retain vector geometry. For physical measurements, print at Actual size or 100% and turn off Fit, Shrink, or Scale to page. Use the first page as a measurement check when printer drivers add non-printable margins.
