How to Export PDF and Print 1:1 Scale on Oversized Paper?

Printing technical drawings at a 1:1 scale on oversized paper or continuous paper rolls (exceeding A0 size) is critical for accuracy. Whether you are dealing with massive blueprints or long structural layouts received from a designer, you don't need expensive software like AutoCAD to get the job done.

CAD Reader offers a built-in feature to print custom sizes seamlessly, ensuring your physical prints perfectly match your digital designs.

Common Industry Use Cases

Large-format, true-scale printing is essential across various professional fields:

  • Architecture & Engineering: Large construction plans, site layouts, and infrastructure schematics requiring continuous roll paper for scale accuracy.
  • Surveying & Mapping: Topographic maps, land surveys, and GIS outputs printed on long rolls to capture extended terrain.
  • Garment & Textile Printing: Full-scale fashion patterns, curtain layouts, and upholstery templates printed on continuous rolls for precise cutting.
  • Packaging & Industrial Design: 1:1 scale die-cut templates for boxes, cartons, and product packaging.
  • CAD/CAM Manufacturing: Machine part outlines, cutting guides, and CNC templates that require exact alignment during fabrication.
  • Advertising & Event Graphics: Banners, posters, retail signage, exhibition backdrops, and booth panels.


Step-by-Step Guide: Exporting 1:1 Scale to Custom Sizes:

If your drawing does not already have a border, you must create one. This boundary acts as your reference dimension to limit the printing area according to your paper size.
