wow thanks for the quick response guys! That was exactly wht I was looking for!

I have another quick question... How can I project an aerial photo onto this terrain?

Thanks a ton!

Hi!

I'm trying to model a small town in sketchup. I'm using the sandbox tool to create the terrain from contours positioned at the correct elevation. What I can't figure out is how to do the roads! How do I draw them? They have to slope with the terrain, but how do I draw on such a surface when it's interpolated from the contours? I would like to be able to attach a different material to the roads and I need them sloping exactly as the terrain does, I basically need to be able to draw on my terrain... any ideas on how to achieve this? Different methods you have used in the past?

Many thanks!
