Hi,
I've been asked at my job to take a stormwater Management drawing and use the contours to create several trap lows at certain specific elevations and tell the designer the areas for each one.
I've imported the drawing and it's surfaces into Civil 3d. However, so far I can't find a way to use Civil3d to automatically calculate these trap lows and draw them for me. Has anyone done this?
For those who don't know a trap low is simply put, an area that is designated to trap water. We try to calculate a probably yearly rainfall, and then also a major rainfall even that might happen every 1 in 100 years. The 1:100 is the maximum height and depth elevation of the trap low, which also describes the total area of the trap low.
So far, I haven't successfully used the grading tools to do this, and I'm at a loss for how to pull this off.
