Civil3D Surface Analysis Slopes

Hi Everyone, I don’t find myself posting a lot here but could not find anything on the Surface Analysis other than the Elevations, so here goes…

I often have to evaluate designs in terms of slopes and slope arrows. The variations of criteria (for roads up to 10% but for earthworks up to 100% or sometimes simple above and under certain slopes makes me enter the properties and band a lot. I used the method ImportElevations/ExportElevations and I took the basics from this post:

Civil 3D Tin Volume Surface Color Range

Hello - I’m new to dynamo and trying to figure out if I can create a color range to override the surface style for a tin volume surface. Essentially, I want to automate the cut/fill map process with the standards I use regularly. Usually, I use 255, 200, 200 as my 0 to -1 cut color and then use a darker red for each increment of increased cut. For the fill values I do the same with shades of blue (0 to 1 is 200, 200, 255, 1 to 2 is 190, 190, 255, and so on). Is there a way to automate this in d…

Attached the dyn file, it is player ready (I think… even capturing a few errors)

Changed it a little bit to handle the output file only on Export and added slope Arrows. Also decorated it a bit (version and stuff).

Another small inconvenience for this method is that any table will not update until you hit the OK button in the Surface properties window. Somehow apparently the update of a dynamic table is arranged within the Surface properties command. Just so you know, other than that it all works great
