I am always a fan for given users more options to 3D Model/2D Draft the way they like and am not one to subscribe that there is only one way to do things, and although I would welcome more user control with line weights similar to how dashed lines have been enabled in SU, the suggestion Anssi makes is a good one. I recently gave up on Vector and Hybrid in LO and spent the time to adjust my styles to get good results with Raster.
These are the settings I use:
Profiles = 2 (Helps pronounce edges as thicker, lines within a plane tend to show thinner)
Depth = 4 (Line closer to the camera are thicker, those that are farther are thinner)
Section Lines = 4 (very thick line at section cuts)
Set Fog for each scene to fade line work in the distance.
Set Shadows to help communicate forms.
Note: Use Fog and Shadows with caution if you have an older computer.
Here is how that looks in SU on a 3440x1440 screen
In LO I set the SU Viewport Line Scales to 0.20
