For large drawing sets
Drawings slow your PDF viewer down because they are not ordinary PDFs.
A single construction sheet can hold hundreds of thousands of lines, hatches and text runs. Viewers built for documents redraw all of it as pixels, one page at a time. DraftPlanar was built for drawings.
Built from the ground up for drawings
It started with drawing sets that were painful to open. So instead of wrapping an existing PDF engine, we built our own, from reading the file to drawing it on screen, and shaped every step around how drawings are made and how people read them.
Why drawing sets slow viewers down
Hundreds of thousands of shapes
Hatching, dimensions and dense MEP runs pile shapes onto one sheet, and every pan and zoom redraws them.
Pixels that blur
To keep up, many viewers turn a page into an image. Zoom in and it goes soft until the page is drawn again.
One page at a time
Scrolling a 500-page set loads and drops pages over and over, and you lose your place between the plan and the detail.
How DraftPlanar stays fast
Its own renderer
Drawings are drawn directly on the graphics chip, at 60 fps on Mac and iPad, even on 500+ page sets.
Only what you see
The sheets on screen get full detail. Everything else waits quietly until you move to it.
Sharp at any zoom
Lines and text stay vectors, so a 1 mm note is as sharp at 20× as the title block.
Nothing to upload
Rendering and text recognition run on your device. No cloud conversion, no waiting on a network.
Try it on your slowest set
The quickest test is the drawing set that slows you down today. Open it during the 14-day free trial, then pan, zoom and search it.
Questions
- Why is my PDF viewer slow with construction drawings?
- Drawing sheets carry far more vector geometry than ordinary documents. Viewers that redraw every shape on each pan and zoom, or that turn pages into images, slow down or blur on large sets.
- What is a fast PDF viewer for large blueprints on iPad or Mac?
- DraftPlanar is built for this. Its own renderer, made from the ground up for drawings, draws construction PDFs at 60 fps, keeps full detail for the sheets on screen, and works offline on Mac, iPad and iPhone.
- Can DraftPlanar open a 500-page drawing set?
- Yes. Whole sets open side by side on one canvas, and only the sheets on screen are drawn in full detail, so large sets stay responsive, including on iPad.
