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
