Hello everyone I am new to dynamo, I wonder if there is a way to add tin Surface boundaries, to an existing surface. This is how it looks like and how i need it from dynamo skript: [image] Thanks in advance

[image] dforrestMJRCQ: Can you add this to Camber? This is available starting in Camber v4.2.3. [surface_boundaries]

See this [image] Surface.Boundaries node Civil3D Anyone have any luck using the Surface.Boundaries node. It only produces empty lists for me. Is there something that I’m missing? [image]

Hi hosneyalaa Thank you for your answer, but this is not, what i am looking for. I need a use case, where my input is existing surface and 2D-polylines. With dynamo i need to cut out the holes in surface. So my first step was to add 2D-polylines as breaklines (it works), and next step should be …

@anton.opanasenko Because I’m on vacation I can’t help you well but you need Make a new python script And add borders through the link http://docs.autodesk.com/CIV3D/2019/ENU/API_Reference_Guide/html/f0f1dedc-bae9-a2ed-a2ce-3aa457181755.htm

It looks like, it should be the right way, but to be honest, i never did anything in python.

Hi @anton.opanasenko , Here’s a Python script for you to try. I did it quickly and did not do extensive testing, so use at your own risk. IN[0] = surface IN[1] = boundary elements (e.g. Polylines) IN[2] = mid-ordinate distance for curves IN[3] = boundary type as a string, can be “Show”, “Hide”, …

Hi @zachri.jensen I testes it a little bit more, and it works pretty well. Thanks a lot
