after PDF export from Layout, slanted element lines appear jagged, not straight (when viewing the PDF on the screen, not when printed). How can I influence this? Which settings do I have to change? I am grateful for any help.
What is your render setting in Layout? If you are using raster rendering the lines will be jagged. If you are rendering in hybrid or vector they should be straight. Can you attach a screenshot?
Try setting your display and output resolution to high. Click the file dropdown > document setup > rendering. If the viewport is rendered as vector it definitely shouldn’t be pixelated…
