no, crummy I know but no there isn't. I wonder if a plugin could do that but that's a different forum first part no, no sure I get the second part of the question, there are a couple of plugins that offer more specific control of info on the camera, this is one http://forums.sketchucation.com/viewtopic.php?t=21047. The plugin CADup http://forums.sketchucation.com/viewtopic.php?t=35096 will create a series of 2d drawings from your model if that's what you are after. Which version of layout do you have? v2 and v3 have dashed line options under the Shape Style dialog (for lines drawn in layout, v3 can control the scale of the dashes which is key. If you put the model in vector mode you can explode it and alter the line work of the model but it is no longer referenced to the model but you could overlap it with other instance of the model that is still referenced. I'm not sure about the method you are alluding but another option is to put the model in vector mode and to a scale, then export a pdf, import it into illustrator and everything comes in nicely so can use layout to get sketchup models into illustrator. There is a plugin that will replace a complex shape with a basic shape(proxy or placeholder), but I haven't tried it but the author suggests you can go back and forth between them in the menu. http://forums.sketchucation.com/viewtopic.php?p=179977#p179977. There might be another version out there as well.

Hope this helps
