How to form hills that flow across multiple faces?
-
I have a city modeled out, but I need to put some hill into the terrain so it is not so bland and completely flat. Problem is, It needs to affect multiple faces and only of the ground faces. Not sure how to go about this... please help! Thanks

Hi, I don't quite understand what you're saying "It needs to affect multiple faces and only of the ground faces."
Do you have a jpg you could show what you mean? Or attach the model?

Hi Bpear, I think you may have put the cart before the horse here.
I think the workflow should have gone like this:Build the terrain.(sandbox tools) When you are happy with that "drape"(sandbox tools) the road layout over the terrain. This will fix the road to the terrain. Then place the buildings on the new terrain.
If there is a way to manipulate the existing planar Landscape, without causing all sorts of issues, I for one be looking on with great interest.
Just in case: window/preferences/extensions/click sandbox tools.
Cheers

Yeah, I had a feeling. Kinda sucks but, usually big city sections are mostly flat, so I'll roll with it and just make the surrounding terrain with hills and such..
Thanks anyway though.
...and if anyone thinks of a way, post it!

If I had to do it, I would:
- Draw my rolling hills inside a group, totally separate from the city grid.
- Then I'd move it directly underneath the city.
- Then I would drape the city roads onto the terrain. Do this part in small increments as it is quite likely it will crash sketchup a lot. So grab about a blow worth of the city terrain and drape it. If it doesn't crash, save the file, then move on to the next block. If it does crash, open the model and try doing only half the block.
- Then once all the roads and parcels are draped, I would use drop.rb from http://www.smustard.com to drop all the building straight down onto the terrain. Many will end up with corners showing above the terrain, so then move them down the rest of the way until they are entirely hidden. This will not work as easily as I describe if your buildings have entry doors and such as they could end up partially buried.
Anyhow, that's how I do it. Good luck!
