We are Fire Risk Assessors so mainly we use BlueBeam (Revu 21.9) to colour in the centre of walls to signify the fire resistance we want. On one drawing the walls are thin black lines, not matter how much you zoom in via Bluebeam. But if you open the PDF file on various PDF reader the wall lines are now each about a third of the thickness of the wall. Making our colouring difficult to see.
If we turn off "Disable Line Weights" in Bluebeam then we see the same as the PDF reader. But I cannot seem to get it to disable line weights in the PDF file whatever I do. The walls in question are baked into the PDF file we got from the client and cannot be unflattened.
Tried printing to PDF as a Vector and Image to no noticeable difference in line thickness.
Anyone got any ideas?
