What do I have to specify in LO in order to export the vector type only? I'm making possibly a big assumption that LO's vector PDF exporter is different (bug-free) than SU's...
In Layout, you can select the view and set it's rendering style in the Sketchup Model "tab" in the Tray
It is hardly helpful, but the problem is, I understand, that all hidden line algorithms have to limit their accuracy, because they cannot keep caculating indefinitely. So always some lines that are directly on a surface are interpreted as hiding behind it, leading to missed lines. Besides SU PDF and DWG exports, I have seen the same with hidden-line exports from Autocad too. I have not tried if it is the same with Archicad and Revit too.
