Would love to see the Back edges linestyle in sketchup with the dashed line indicating whatever elements lie behind the object in view able to be used with Vector linestyle in Layout. For whatever reason this does not translate into Layout when you use Vector or Hybrid mode. Only with Raster. Problem with Raster is that then you end up with all the other lines displaying that jagged edge of pixels.
The workaround is to create two SketchUp vector views, one with hidden lines and one a wireframe and superimpose them. Then you can explode the wireframe view which yields a LayOut group that accepts a linetype. The downside is that you have to repeat the process every time you make changes to your SketchUp model.
