Batch create volumetric surfaces

Hello guys, what i’m trying to achieve rn is exactly the topic name, batch creating volumetric surfaces between my already existing TINsurfaces. I’ve searched the forum and the closest I got from it was this post: Getting surface information from C3D using Python - #5 by jduran

but i can’t seen to do this operation for multiple inputs! any help around this issue?

thanks in advance

Hello,

Is not simple but you’ll have to create every volumetric surface that you need like this:

CommandMethod("CreateTinVolumeSurface")]
public void CreateTinVolumeSurface()
{
    using (Transaction ts = Application.DocumentManager.MdiActiveDocument.Database.TransactionManager.StartTransaction())
    {
        string surfaceName = "ExampleVolumeSurface";
        // Prompt user to select surfaces to use
        // promptForTinSurface uses Editor.GetEntity() to select a TIN surface
        ObjectId baseId = promptForTinSurface("Select the base surface");
        ObjectId comparisonId = promptForTinSurface("Select the comparison surface");

        try
        {
            // Create the surface
            ObjectId surfaceId = TinVolumeSurface.Create(surfaceName, baseId, comparisonId);
            TinVolumeSurface surface = surfaceId.GetObject(OpenMode.ForWrite) as TinVolumeSurface;
        }

        catch (System.Exception e)
        {
            editor.WriteMessage("Surface create failed: {0}", e.Message);
        }

        // commit the create action
        ts.Commit();
    }
}

You’ll need to adjust that for python if you want to do it in Dynamo.
Hope this helps

Hi, are you looking for solution how to repeat one function for multiple inputs stored in a list? I hope this can help you Create Profile - #26 by Drbohlav. Or google "For Loop“ and “List Comprehensions”.

Based on the topic you mentioned in the first post I created the following:

				    j.Erase()
			    t.Commit()
    return output

OUT = get_tinvolumesurface_Vol(IN[0], IN[1], IN[2], IN[3], IN[4])

Not the most cleanest code but it is functional. It is however required to have some basic knowledge of python to start with this :slight_smile: .

Hi @stabouw, sorry for the late reply. I used your script and adapted it for my needs (I needed the volumetric surfaces created to make solids from them, exclusively) and it works perfectly.

Thank you very much for you help.

First thanks for your post!

When I use this script to retrieve volume of a iteratively generated TinVolumeSurface based on a corridor, as the subassembly parameters of the corridor varies. I met tow problems:

  1. “TinVolumeSurface.Create Method (surfaceName, baseSurfaceId, comparisonSurfaceId, styleId)”
    styleId is The ObjectId of the SurfaceStyle for the TinVolumeSurface, but I don’t know how to get a styleId.
  2. I want to get the volume info of the generated TinVolumeSurface every time the associated corridor is updated, how can I connect these two things, the corridor updates and create & retrieve info of the TinVolumeSurface?

Thanks very much!

For surface style
try this is

 cdoc = CivilApplication.ActiveDocument 
 styleId = cdoc.Styles.SurfaceStyles[0]
      

Thanks very much! I tried as your advice, it works.

from Autodesk.Civil.ApplicationServices import *
cdoc = CivilApplication.ActiveDocument

rst = []
for style in cdoc.Styles.SurfaceStyles:
	rst.append(style)
 	
OUT = rst

For selecting a surface style I used this Python code, the output is dictionary of all available surface styles.

Running a dynamo script automatically is something which as far as I know cannot be done in Dynamo itself. You could probably pick up corridor updates in the Civil .NET API and then trigger the dynamo script, but I have no experience with that.
