Terrian mental block wall

[sbok5150]

Greetings all, Ok tried all different combo's in the Edit terrian pull down window and can't figure out how to lower my drive way down to the garage. Emphasizing lowering the drive way only and not any surrounding terrian. Looking foreward to your suggestions.

Thank you Sean


See if this link works

Sean,

Your picture isn't posting - but I might know what you're asking.

Here's how I get terrain elevations to behave. I learned it from Steve, who knows everything!

1 - When you make your terrain perimeter, open it up and uncheck "auto calculate elevation", and set it to zero.

2 - in the Terrain Configuration child tools: choose Terrain Elevation Tools, then the Elevation Line child. Draw contour lines like you would see on a topographic site plan. If your garage floor is at -12", have a line going pretty much straight across the garage doors, and set that line at -12". Set the heights of your other elevation lines by how far above or below your finished first floor they should be. You'll get perfect grade heights every time.

By the way, Dermot told me that for best results, use fewer lines, not more. I was loading up on many lines, and it turns out a few strategically placed is better. With too many too close together, I used to get crossed polyline errors.

Sean,

Does that drive go up to a retaining wall? Pull the retaining wall back and the drive will drop down,

...and Wendy is right less is better when doing terrain.

[louis]

Will this work?

...or put the road over the creek.

You might want to do as Louis did in making a simpler plan for practice with the terrain tools till you get the right combination of modifiers, retaining walls and elevation data figured out and then transfer that new understanding to your main plan. Successful practice will lead to certainty for you.

Well Louis your pic looks great, but for my situationn that back retaining wall must stay there the only part of the terrian that is lower or goes lower is just the drive way. Everything else must stay at the street level.

Thank you again Sean

Louis!
I can't believe you forgot the culvert!

[louis]

It's in there you just can't see it. High water.

Then have your retaining wall but make it a regular block wall (not a retaining wall that effects the terrain) and try that. There is always a solution and usually more than one.
