Hi guys,
How are you?
I'm working in a project that can't have a slope over 30%.
But I don't know how to fix it, I was trying to create a feature line and raise my surface about 2meters.
It isn't working properly, and I need some help.
I'm attaching my drawing.
Thank in advance.

You can add a breakline, which will affect the surface elevation in close proximity to the breakline, but there are other elevations defining the existing surface elevations/slope, so the effect is localised. I notice all of your lot boundaries are at an elevation of 819. It would seem that the best solution would be to create a separate surface, which is effectively a level pad for your lots, possibly with a few intermediate breaklines/contours sloping away from the lots. This would create a new surface with compliant slopes. Once you are happy with this, paste this surface into your existing surface and you will end up with a combined surface adhering to your slope criteria.
Cheers

Are you not engineering these slope to be within the stated parameters? I cant open you file at this time
Hi Joe,
I'm modeling the corridors, the lots and others areas couldn't.
But I can not have slope over 30% for lots and institucional area. And I'm trying to fix it.
Let me know if you could open the file, and I attached it again.
Thanks

Mick, thank for replay 🙂
Could you make a dwg for explain better the task, please?
It will help me a lot.
Thanks
I've done a very rough example in the screencast below - you would need to take more care with the edges and achieving the right slopes, but I hope this demonstrates the principle. The idea is to create a finished ground surface as you would like it, and paste it in to your existing surface. This effectively replaces that small section of the original surface with your new section.
You will see that I created the replacement surface section by using your existing boundary (which was at the right elevation already) and just adding it as a breakline. You will probabaly want to have numerous breaklines and contours at different elevations to help define the landform better than my 62 second version.
I hope this helps

Your streets are too steep. Fix that, then design a nice safe tiered wall system in that steep tract.

Mick,
Thanks! 🙂
Great screencast.
In you screen cast the contours has gone! See the image bellow.
I'd like to get the slope under 30%.
I'm trying to create a feature line and change the elevation.
Help me friends, please.

Hi Fred,
Yes, my streets are too steep!
I can't fix better than that, the natural surface is very steep.
I'm trying to modeling the surface to make it better.
If I create a feature line at the botton of the institucional are and raise about 5 meters. It will work?
@F.Camargo Yes, in my screencast I just pasted in a flat surface, but the point was that could could create a any surface you want very quickly and paste it in. If for instance, if you drew some contours as you have in your last post, assigned the correct elevations and added them to a new surface, then pasted that surface into your existing ground surface, you would get the slopes as you want them.
If on the other hand, you just drew those contours and added them directly to your existing surface (without using the new surface) then you would find that the influence of each of those contours would be limited by the other existing surface triangles and you would not achieve what you want.

Hi guys,
I'm back. 🙂
I'm still working in the project. maybe I have a better solution!
And I need some help to do that.
I created a feature line around the area that I need to change...
At the image bellow I create a green line as a example with elevations.
I have calculated the slope for that situation and it's OK!
Could you help me please?
Thanks
