Hi
See this, may help you

23

Can you use
Qty earthwork
Try
Surface 1 compare
Surface 2 base
Surface 3 base

I know that through several steps in civil 3d, what I indicate can be achieved.
But since Dynamo is used to automate processes, I wanted to know if it is possible to achieve it and have a shorter process to obtain that desired volume.

It’s an interesting idea. Ill take a look into it when I get a chance. Don’t have computer access for a bit. *Edit: Won’t have C3D access until the 11th due to being between jobs.

@Edwin.Saez , Sorry for the delay. I just started a new job and I’ve been having less time/an adjustment period + other personal matters. Here is your solution. It will get the combined boundary of two selected surfaces and generate a grid based on the grid spacing input, so decrease the spacing if you want higher accuracy. Where surface 1 exists and surface 2 doesn’t, points on surface 1 will be returned for the new surface and vice versa. Where surface 1 and surface 2 overlaps, the point that is returned is the one with the lower z value. The script then creates a new surface named “combined_surface” and adds the verticies to generate the surface you intend to compare with surface 3. You may have to trim off triangulation or add a boundary manually. I couldn’t find the add surface boundary command exposed in the API.

@mzjensen Any intention to add “AddVertices” to tinSurface to camber? I wouldn’t of had to go into python if I had it available. :sweat_smile: I did notice that “AddVertices” was throwing an exception when the surface was empty. Not sure why. I just iterated with the “AddVertex” Method.
