I just loaded 2018. Looks pretty good and I like the new section fills so far.
But, I am having a problem with lines in a SU model loaded into LO that appear in raster mode do not show up in vector or hybrid mode. I am not sure this is an 18 problem, but it is new for me and disturbing. Not all of the lines drop out, but just some. It does not appear to be related to the section fills. I have tried resaving and reloading the model with and without the section fill turned on.
Sigh. I too had random errors like this with v. 2017 and older, especially with section cut edges. To me it seemed like v. 2018 had fixed them. It seems totally random - at least I don’t know what to actually do to make this occur.
I was able to reproduce that too. I had tried to do that but was not systematic, and I did not un hide all of the lines. Problem solved sort of. I hid the edges so I would not see the floor lines in the 3d views from outside. It was a nice effect. There are other ways to do that, but for a quick study as a preliminary drawing for a new client it worked very well until I tried to print the plans. I hesitate to call it a glitch, but I wish it worked a bit differently.
I’m not certain but I’m thinking this might be a work around. Why the section cut lines aren’t showing in Vector or Hybrid is a puzzle to me. Is it because they are raster lines in SU and not vector lines like edges? Maybe @trent will have some input.
Hiding those edges in that case makes sense to me but I think you’d need to use a different approach for the section cut at this time. You could make a section cut face use Group from Slice or TIGs Add Section Cut face. I might be inclined to put the section cut face in a separate scene and then stack viewports for that. Or you could use the Section Fill as you did but set the fill color to black.
