PDF viewer for technical drawings · Mac · Windows
Whole drawing sets. Every line sharp.
LessPDF opens construction sets with hundreds of A0 sheets, switches their layers, measures to scale and keeps your markup in the PDF. It runs on your computer and never uploads a file.
Sample set: Lindenhof Block C, 412 A0 sheets with eight layers. The live demo opens it in your browser.
Sheet A-103 of 412, zoomed to 400 %.
From the whole sheet to one riser
Pages render in tiles and sharpen in place as you zoom. The vectors stay vectors, so a revision cloud at grid 8/C reads as clearly as the overview.

All featuresLayers and sheet numbers
Switch architecture, structure and services on and off, search the whole set, and go to a sheet by its label.
Measure to scale
Calibrate each page by two points or its drawing scale, then measure distance, perimeter and area.
Markup that other apps read
Revision clouds, callouts, stamps and comments are standard PDF annotations, saved into the file.
Organise the set
Reorder, rotate, insert and delete sheets, merge consultants' files, split by discipline, all undoable until you save.
Tabs, windows, ⌘K
