I'm working with a rather complicated site that has lots of ups/downs and retaining walls. I have contour lines from Civil but because there are so many retaining walls (and buildings acting as retaining walls) I'm not sure what the best way to go about modeling this in Sketchup.
Right now my approach has been to clean up the contours as best as I can but I'm not even sure how to best create geometry out of them in Sketchup because of all the disconnected contours (due to retaining walls).
Does anyone know of any good tutorials out there for how to address this?
