Hello everyone,
I've already taken a look on the forum but can't seem to be find anyone with this exact issue.
This is the layout screenshot:

This is my view in sketchup where you can't see the lines:

I've tried changing the graphics settings so the advanced engine is switched off but that doesn't seem to make a difference.
I look forward to anyones advice on this one.
If not I might have a work around by using raster with a duplicate view other the top in Vector.
Best,
Adam
