So, I thought I figured it out, but now the situation has gotten worse, and weirder. I am attaching a link to a dropbox folder with the files, I have stripped out all the scenes that seem to be working fine from the SU model, and I have deleted all the pages that seem to be working fine in LO.
Here’s what’s happening: I have been roughly using the Sketchup for Architecture system for creating floor plans, etc. Out of the blue, my heavy-line scenes have started to act extremely strangely. As you could see in the pdf link above, some of the lines changed both line-weight and color within the same viewport. I didn’t think that was possible. That problem seems to have gone away, but now all the heavy line weight scenes do not show most of the line-work, but only when they are vector rendered. They show up fine if rendered in raster. So, the information is there, but suddenly whatever the rendering engine needs to see the lines as vectors is not there. I have tried opening a new layout document and inserting the scene into it, and I get the same behavior. This suggests that I have somehow managed to screw up my SU file in someway that I can’t figure out.
One other piece of the puzzle is that I was able to make the initial problem of the colored lines go away by applying the default color to the group that held that geometry. I don’t really see why that would change anything, but it did seem to make the initial problem go away. But I cannot seem to reproduce the fix with the larger problem that has emerged.
Thank you in advance to anyone to takes the time to help me sort out this mess. I am sure it is something I have done wrong in my modeling.
All the best,
