Hi everybody, Il would like to create a surface from a 2D ou 3D polyline. I managed to extract the points from my closed polyline [extract-points_poly] Now i would like to add these points to my surface using a Pyhton Script, but the method .AddVertices ask for Point3DCollection. How can i tra…

Are you wanting to create a TIN surface in Civil 3D or a surface/polysurface in Dynamo?

OK before going the API route (more work), is it an option in your workflow to use the TinSurfaceExtensions nodes from the Civil 3D Toolkit or the OOTB node to create a surface from a COGO point group?

For some reasons, I don’t want to create CogoPoints. i want to use the .AddVertices method for TinSurface. But i when i create a Point3DCollection i have this message : Avertissement:IronPythonEvaluator.EvaluateIronPythonScript l’opération a échoué. Traceback (most recent call last): File “”, l…

it’s “Point3d” lower case “d”

Thanks @Paolo_Emilio_Serra1 ! i feel so ashamed… I have a new issue. Here is the message i get : Avertissement:IronPythonEvaluator.EvaluateIronPythonScript l’opération a échoué. Traceback (most recent call last): File “”, line 96, in File “”, line 77, in new_surf TypeError: unsupported operan…

It’s actually the line above that initializes the for loop (known issue with the line number in the Python editor). You need to count the points, use this range(len(nb_pts) - 1))

Thanks @Paolo_Emilio_Serra1 Here is my code complete code. I have (again) an issue when adding a contour to my surface. When the polyline that define the contour is convex it works fine, but when it’s concave the surface is deleted by the add of contour… surface_from_poly.dyn (18.3 KB) @Paolo_Emil…

[image] frederic.duhart: it would a good idea to add a new node to Civil3DToolkit that can ass a contour to a surface It is already possible. [AddContour]

The node you mention add BreakLines, and not Contours. I tried it, and it doesn’t work for my purpose. … or i don’t understand hiw to use it!

It is already possible.
