@Alessandro1985 Cogo points will be covered in the next release. Also there is an advanced sample shipped with Dynamo for Civil 3D that shows how to create a Dynamo node in C# to address Cogo Points. Have a look at this example Python script I’ve put together. It creates a proxy class (DynCogoPoint) that contains some parameters and manages the update or creation of actual Civil 3D CogoPoint. It should get you going.CogoPoints.dyn (8.8 KB)
