Hi, I would like analyze TIN surface. I’m not sure if Dynamo can help. I tried to use TIN surface wateshed analysis, but it was not solution for this.
I’m looking for local depressions area in surface where water will stay after rain. In the picture are contours in 1mm elevation step in one place of many surface depressions. I’m looking for contour with highest elevation in such place.
you could do a slope analysis or elevation analysis. These can identify where in the surface water will stay and drain to
Can you show me how you can do this analysis using Dynamo? I’m looking for solution how to define all areas where water will stay after rain.
The input should be only TIN surface.
first create a surface style in civil3d that has slope display ‘on’. That’s the “slope design check” node. Make the select surface node an input node.
Then set your parameters for slope (you can make any parameter range you want to be viewed on the surface). Here I have slope parameters in:
red = 0%-1% slope
Green = 1%-33.33% slope
Blue = 33.33%-99.99% slope
Did you have any questions?
