Ok then
Here is a copy of my sketchup file. I have used layers and set up some scenes. Another problem I have just discovered is that if I set a scene up with dimensions on it they suddenly dissapear from all the scenes I have made if I remove them from the main drawing to make a scene with no dimensions?
I don't get the viewport setup comment. The way I am trying to set the layout is by reducing the drawing layers down to just the window, centering the drawing, editing to a point where I can take a section, take a section slice, revolve it and then send to layout. Where I can create a workshop drawing to be printed off. With all relevant dimensions etc.
I hope you can follow this and I'm sure there is a very simple system to do this. Hope you can help/.
