What are Breaklines in Civil 3D?
Breaklines are line data that can improve a surface. They provide more information to the surface and influence how it is triangulated. Adding a breakline forces the surface to create triangles connecting the vertices on the breakline.
How do you use breaklines in Civil 3D?
Use the Add Breaklines dialog box to define features, such as retaining walls or curbs as breaklines. Use the Add Breaklines dialog box to create a non-destructive breakline from either a grading feature line or an open or closed AutoCAD object. Edit any breakline that you have defined by selecting it in the drawing.
What are Breaklines?
Breaklines are lines that tell 3D Analyst that there is a distinct change in slope on either side of the line. They are used to represent surface formations like ridges, streams, dams, shorelines, and building footprints.
How do you resolve crossing breaklines in Civil 3D?
Click Analyze tab Ground Data Resolve Crossing Breaklines Find. At the dynamic input prompt or at the command line, specify the location to look for crossing breaklines: Survey Database, Figure, or Surface. To view the crossing breaklines in the drawing, click an item in the list and then click Zoom To.
What are Breaklines in AutoCAD?
By definition, a Break line in AutoCAD is a polyline in which a break line symbol is incorporated. Such a line may be manually created using the LINE command or most conveniently created using the BREAKLINE command.
What are Breaklines used to show?
A Breakline is a line used to connect data representing a distinct surface feature, like a ridge line, edge of pavement, toe of a slope, centreline of a road, or flowline of a ditch or stream.
What are the 4 types of boundaries in Civil 3d?
There are 4 types of boundaries; Outer, Hide, Show and Data clip.
Can contours cross Breaklines?
Contours will cross breaklines that have elevations that bracket the contour elevation. Breaklines do not prevent contours from crossing them. Breaklines (should) prevent triangles from crossing them. It looks like the surface is recognizing a breakline at the house boundary.

How do you change line break size in AutoCAD?
To Draw the breaklin you type BREAKLINE an ENTER, then, if you look at the command you will see this text: At this point and before clickon to start drawing, you can type “S” and press enter and you will be able to modify teh Size of the BREAKLINE symbol.
Can a surface have two boundaries?
Note: You can define multiple outer boundaries, but only the last defined outer boundary is displayed. You can use the surface definition to switch between multiple outer boundaries.
Can you clip a surface in Civil 3D?
You can apply a Data Clip boundary to surfaces created from imported data files, including TIN, LandXML, grading, or corridor surfaces.
What are weeding factors in Civil 3d?
Answer. Weeding is the removal of points along a selected polyline representing a contour. The weeding factors determine the amount of points removed. You can use weeding to reduce the amount of point information taken from the contours that may not be necessary to generate an accurate surface.

What is a surface mask Civil 3D?
Products and versions covered. Civil 3D 2019. Jul 17 2019In-product view. Use masks to block out areas of a surface and prevent them from being displayed or to render a section of the surface using a specified render material.
How do you smooth jagged contour lines in Civil 3D?
To smooth the contours, go into the style the surface is using and, on the contours tab, toggle the option to smooth the contours to True. Once you have this toggled on, you can select the type of smoothing you want to apply to the surface as well as how aggressive you want the contour smoothing to be.
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.

How do you remove vertices from a polyline?
To Delete a Vertex in a Polyline
- Click Home tab Modify panel Edit Polyline.
- Select a polyline.
- Enter e (Edit vertex).
- Enter s (Straighten).
- Use the Next option to move the X to the vertex immediately following the one that you want to delete.
- Enter g (Go).
- Enter x (Exit) to end editing vertices.
What is a phantom line used for?
Phantom lines are long-short-short-long lines most often used to show the travel or movement of an object or a part in alternate positions. It can also be used to show adjacent objects or features.
