GMcGee Posted April 30, 2023 Share Posted April 30, 2023 Hello, I am putting in an elevation region over contour lines I have put in the site. When I add the elevation region, CA adds new contour lines around my elevation region. Does anyone have any suggestion on why this is doing this and how to fix? For context, the triangle is the building setback area, which we want to make level for the structures. After Before DAVIS.plan Link to comment Share on other sites More sharing options...
Chopsaw Posted April 30, 2023 Share Posted April 30, 2023 Yes you have created a situation where you now have conflicting elevation data so just as in real life you would need to remove the extra information from below the pad and then taper off the edges.

DBCooper Posted April 30, 2023 Share Posted April 30, 2023 An elevation region says that everything in that region is the same elevation. An elevation line says that everything along that line is the same elevation. Since your lines go through your region, the program can't create terrain at both heights and will give you strange results. If you convert the elevation region into a flat region, you will get better results. Probably still not ideal though because it won't do a great job with the cut and fill. To get better results, you will have to add/remove elevation data to taper off the edges how you would like them (as suggested by Chopsaw).

GMcGee Posted April 30, 2023 Author Share Posted April 30, 2023 Thanks. So I cleared the terrain, cut the terrain lines and re-built. Still getting some weird edge effects. Any further thoughts? Link to comment Share on other sites More sharing options...

The fact is we have limited ability to properly and predictably sculpt terrain in Chief, for the moment. Instead of downvoting, prove me wrong.

Joe_Carrick Posted April 30, 2023 Share Posted April 30, 2023 Don't use so many elevation lines. If none of the elevation lines intersect the elevation region edge Chief will smooth out the terrain. I would at a minimum delete elevation lines 5,6,7 & 8 and modify the triangular elevation region so it's a trapazoid (cut off a bit of the top point. 2 Link to comment Share on other sites More sharing options...

Any further thoughts? looks good so far just pull the elevation lines back away from the edge of the region maybe 2-4' and see how that is. Maybe more. 2 Link to comment Share on other sites More sharing options...

So the reason that you are having problems at the edges is because you still have two different elevations at the same point. Your elevation region is one height and the ends of your elevation lines are at a different height and they are right on the edge of the elevation region. Try Chopsaw's suggestion of pulling the elevation lines back from the region. Then the terrain can adjust from one elevation to the next one more smoothly.

Chief’s terrain tools have not improved or changed since X6 or X7, when I first started paying for SSA. We’re at X15 now. You’re good with this?

You’re good with this? Do I think Chief should improve their terrain tools? Absolutely. I'm 100% in favor of that. But again, how does that help GMcGee's solve his problems?
