Feature lines are 3D objects which can be used as grading footprints, surface breaklines, and as corridor baselines. About the Feature Lines Collection (Prospector Tab) Use the Feature Lines collection in the Prospector tree to manage feature line styles and layers.
Which object can create a feature line?
You can create a feature line by converting existing 2D or 3D polylines, lines, or arcs. You can select objects in the current drawing or from an Xref. Names can be assigned to feature lines. Any command that prompts to select a feature line includes an option to select by name from a list.
How do you assign elevations in Civil 3D?

- In the Set Elevations From Surface dialog box, select a surface.
- Select the Insert Intermediate Grade Break Points check box to insert intermediate grade breaks where the entity crosses surface TIN lines.
How do you create a grade between two feature lines?
When those two feature lines are added to a surface the slope will be calculated automatically when it triangulates between them. The only other thing you could do is delete one of them and use a grading object to create the second FL.
How do you grade a surface in Civil 3d?
On the Grading Creation Tools toolbar, click Select a Criteria Set. In the Select A Criteria Set dialog box, ensure that Basic Set is selected. Click OK. From the Select a Grading Criteria list, select Grade To Surface .
How do I change the appearance line elevations?
