What does weeding mean in Civil 3D?

What is Autocad weeding?

Use the Weed Vertices command to reduce the number of vertices on a feature line. Vertices are weeded if found to be unnecessary for line location, based on weeding factors of angle, grade, length, and 3D distance.

What does weeding a feature line do?

The weeding factors delete vertices that: Are closer together in 2D space to their two neighboring vertices than the Length factor. Have a 2D deflection angle that is less than the Angle factor.

What are supplementing factors in Civil 3D?

The supplementing distance is the maximum distance between vertices. If the distance between vertices on a contour is greater than the supplementing factor, then points are added along the contour at equal intervals that are less than or equal to the supplementing distance.

What is mid ordinate distance Civil 3d?

Well, it’s the distance from the midpoint of a curve to the midpoint of the arc. Mid Ordinate Distance. When you add something like a curve to your surface as a breakline, boundary, or contour; the surface cannot follow the curve so it uses the Mid Ordinate Distance to approximate the curve.

How do you trim a feature line in Civil 3d?

To Trim a Feature Line

1. Click Modify tab Edit Geometry panel Trim Find.
2. Select the objects to serve as cutting edges.
3. Select the feature line(s) to trim.

How do I delete a feature line in Civil 3d?

How do you remove a curve from a feature line in Civil 3d?

…

When adding contours to a surface What do weeding factors control?

The Weeding Factors filter out vertices too close together through the application of a Weeding Distance and Weeding Angle, which are applied together to filter along each contour. The first three vertices of a contour are shown in Figure 1.40.
