It’s so much better than the other PDF things I’ve used. I can measure drawings, set dimensioning scale, comment, edit, all easily. I don’t know why more software doesn’t take their lead. Bluebeam is industry standard for my world and it’s way more expensive and way worse of a product. Pdfxchange users unite!

Have dimensioning and scaling on there? I have yet to find a good PDF program in Linux for working with architectural drawings. In Windows I use pdfxchange (and also through wine in Linux) but would love a native solution.
