Pdf file size
Most important: vector or raster pdf
Raster pdfs file size doesn’t depend on the number of displayed elements, only on the resolution.
Vector pdfs file size can grow huge if you display a lot of elements, or if you use heavy hatches. However as they are vectors, they don’t have a resolution, you can zoom in indefinitely (or until the pdf viewer lets you zoom in) without losing a detail. Also view scale doesn’t matter with vector printing, 1:50 and 1:100 should generate similar file size.
Revit will show you a warning if you select vector, but it can only print in raster. The reasons for this are in the help: Revit help
Which one is the better depends on the use case of the pdfs:
- If you will just print them, display on a monitor doesn’t matter, than check the resolution of the printer and print a raster pdf in that resolution.
- If you want to view it on a screen, it’s better to stay on vector. Try to repace your hatches to something not that heavy, a lot of hatches contain unnecessary lines. Also check if some families has a lot of lines which are hidden by lineweight.
