I expect I am doing something wrong. I have a drawing with scenes set up which look different in SU and LO, despite updating the reference. The two differences I have noticed are that extension lines are more pronounced in LO and there are some rogue vertical lines below "ground level in SU that don’t show in SU. I cannot figure out why it is not WYSIWYG. I am attaching PDFs of the same scene in SU and LO.
