When Civil 3D calcs pipe slopes it uses the inverts of the pipe and the 2D distance between endpoints of the pipe. However when we label the pipe distance we like to "Round Normal" when showing the length of the pipe. The problem we're having is when you then do the math on the rounded distance and inverts of the pipe, the slope is wildly different from Civil 3D's slope. The question is can you tell Civil 3D to round the pipe distance using "Round Normal" first and then calc the slope of the pipe. The only reason this can be, and is and issue is we have an in-house review team that calcs out the slopes with a calculator to check our work and they're constently coming up with different slopes from what the label shows. I'd like for Civil 3D to be able to see the distance of the pipe as 55.345 linear feet but still use 55 linear feet for the slope calc. Can this be done? Is there anywhere you can tell C3D to round the raw numbers?
