how to place lots over bumpy terrain?

[arogers]

I want a lot that is like a gorge where the is a big dip in the middle but it continues outside of the lot too. is there anyway around this?

Whoa. Arogers, your post was a bit hard to read. You may want to check what the shift keys on your keyboard do. They're kinda cool.

Maybe you could start with making a lot with the desired bumpy terrain and adjust the terrain around the lot afterwards. I believe there is a cheat that allows you to do that. I can't remember it right now, but you can find it by typing 'help' in the cheat box. It's on the list.
I'm not sure if this would work, but it's worth giving it a try.

Cheat won't work in the space occupied by the lot. It's pretty much useless unless you use it before placing any lots in the area.

The cheat you want to use is "modifyNeighborhoodTerrain on", with no quotations, obviously.  But in order to place a lot over your newly created gorge, you'll need to go to C:\Program Files\EA GAMES\The Sims 2\TSData\Sys\Neighborhood.ini, open that file, scroll down near the bottom, find the line that says "MaxLotSlope=20.0" and change the "20.0" to 80.0, or any other number less than 90.  Do this for every expansion you have, ie, C:\Program Files\EA GAMES\The Sims 2 University (or Nightlife, Pets, Seasons, Apartment Life)\TSData\Sys\Neighborhood.ini. 

That cheat only came out with Free Time.  If you don't have that expansion, you'll have to get a premade neighborhood terrain with a built-in gorge. 

Oh, and back up your Neighborhood.ini file just in case you screw it up, or it turns out I'm talking completely out of my arse.

One thing you could do is take a 6x6 lot (or whatever the largest one is) and plop it down there and do the terrain how you like then assuming the lot you want to put there is smaller it will retain the topography left when you delete the 6x6 lot (when you nuke a lot only the building stuff is gone.... terrain is left completely alone) and you'll be left with a smaller lot inside the gorge or whatever you create. You can also place down multiple lots side by side and edit it how you like in a patchwork style. Edit one then place a NEW lot (wont alter the terrain you just made that way) overlapping where the old was and continue editing. You wont be able to extend the terrain outward away from the street using that (unless there is a road to attach the lots to of course) but it should do fine overall.
