Hello.
Is it possible to find and use the featurelines which are automatically created by a grading?
Theoretically the “gradingline 1” is in the same site as the “feaureline 1”, according to the properties.
Hi
If you attach an example drawing and file .dyn , that would be better
Hi.
Here are the files.
Export_Gradingline.dwg (2.5 MB)
Export_Gradingline.dyn (26.2 KB)
And i don’t want to find the featureline by the name.
The name can vary from project to project.
Hi
You can get featureline from here
May this help you?

This works perfect.
One last question:
Do you know if it is possible to set the featurelines, which are automatically created by the grading, to be named automatically? So i can filter the List with a content…
Object 2 and 3 are also featurelines from the grading. I renamed object 1 myself.
I can’t find a setting that works.
I was looking for a default setting in Civil3D, not in dynamo.
Search in setting
May picture help you
I think you have the wrong setting… Yours is for corridors.
I have changed every featureline-name in the grading settings, but still no name 
Yes, my picture is just an example
How do you make up the grading manually Or by programming?
Can you ask a question, which is better for naming?
