Feature Line Contract For Free

Feature lines are 3D objects which can be used as grading footprints, surface breaklines, and as corridor baselines.

The only way 3D polylines can pull that off is to segment the curve and turn it into lots of little straight lines. Feature Lines don't have that restriction. Another thing that's cool about Feature Lines is that they interact with each other.

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.

Draws a three-dimensional polyline with straight segments. Although the 3D Polyline command does not have as many options as the Polyline command, you can apply editing changes, such as splining, with the Edit Polyline command after the three-dimensional polyline is drawn.

So this is the edge of the gutter, the flow line, the top face, and the top back. So that's what Feature Lines do, they represent edges or linear objects in a three dimensional form in your drawing model.

Use the Break command to break a feature line into two feature lines. The prompts for this command are similar to the AutoCAD Break command. Click two points to specify both sides of the break.
