Which PDF editor actually stays smooth on a heavy BIM sheet set? I benchmarked a dozen and got a few surprises. What do you use?
Disclosure up front, since self-promo rules matter here: I make one of the tools in the test (Ncored). So I am biased, I will not say how mine did, and I am posting this to build a shared reference and hear what you use, not to advertise it. Check all of it yourself.
I am a practising architect, and heavy PDF sets that crawl when you scroll and zoom have annoyed me for years. The exports out of AutoCAD, Revit and ArchiCAD are some of the worst for it, especially multi-discipline packages where the file gets large and every sheet is dense. So I ran one dense drawing through about a dozen PDF editors on one Windows PC and one Mac, same moves in each, and made the file downloadable so anyone can re-run it.
The surprises:
- Bluebeam Revu was not the smoothest on this dense drawing. Once open it loads fast, and its markup and Studio are still the benchmark for coordination, no question. But panning it flashed white and reloaded the primary layers before the detail filled in. Heavy Revu users, if your experience is different I would like to hear it.
- PDF-XChange Editor was surprisingly smooth, though the interface is a dated Windows-toolbar look.
- A couple of consumer editors went choppy or would not load the heavy drawing at all.
Two things I want from this sub:
What do you actually use for heavy AutoCAD, Revit and ArchiCAD PDF sets, and does it hold up when the set gets big and dense?
What should I add or re-test? Name any editor you think belongs, and call out anything you think I got wrong.
I will add your suggestions and re-run them on the same file so it stays a shared reference. The recordings and the downloadable drawing are in the first comment below.
Standard caveat: your hardware and files differ from mine, so it is one data point, not the last word.
