Thanks for that, very helpful. The horizontal weatherboarding lines were done in a hurry and some ended up stood off the surface by an inch in the plane of the window frames rather than on the surface of the walls. Could to better if I tried. I didn't know about front and back surfaces so thanks for that. I've been looking for a problem with the materials or something like that to explain the colour difference! Yes I built it slightly oddly. Basically I built a plain box then fitted an oak frame the same size into it so there will be coincident faces and lines that aren't merged properly. That's ok for my purposes. I'm doing ths model because I need to get approval from my local council to build it. They only want 50:1 elevation drawings and an isometric sketch to approve the appearance. Sketchup's sketchy line styles will be great for the isometric. Once the basic style is approved I'll probably go back to an earlier version which has the frame seperate to help with the design of that. Currently the roof has no structure. Regards, Colin

Ok tried something new. If I draw a larger object say 10 feet x 10 feet and then print it at a smaller scale it does print correctly and the right size. It's just small objects that it seems to have problems with. Edit: Oh B%*%%$er now even that's stoped working. Last week I designed a stable block thats a 16 x 16 foot and 12 foot high. Printed out fine to scale on one sheet of A4. Can't get it to do that now. Will try reinstalling sketchup incase something has gone wrong.

Have you resolved your issue? Mike RL

You can make your own styles too. edit; yes csaba, sorry didn't think of that
