Measurements are stored in millimetres. Inch inputs are converted at 25.4 mm per inch. Print PDFs at Actual size or 100%.

How this pattern works

The engine constructs vertical and plus/minus 30-degree line families with perpendicular spacing derived from the selected interval.

How to use the generator

  1. Choose a preset or adjust the pattern-specific measurements.
  2. Select the paper size, orientation, units, margins, colors, and line weight.
  3. Review the live preview and correct any validation warning.
  4. Download vector PDF or SVG, create a 150/300 DPI PNG, or print from the browser.

Practical uses

  • 3D product sketches
  • Architecture and block diagrams
  • Voxel and game-level planning

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.
