I'm working with QGIS 3.0.2-Girona on Windows 7 64bits. I have a lot of roads on a large map (30 x 40 km approximately). I am trying to export them into vectorial format to print a map. However, the lines are rasterized and I have to make a very huge zoom (1:4000 in EPSG:2154, Lambert 93). Is it because there are too many elements?
I've seen QGIS exporting huge SVG and have tried printing to pdf but obviously, it got rasterized. I will try to find a ubuntu 64 or to run it on a VM.
Is there any other suggestion? Is this a bug from Qt libs as suggested on some posts?
