Length: 3 min. make a grading at 3:1 "by distance" where the distance is larger than the delta to your outside line. I have established an Alignment along the Centre Line of the Also, poly lines can be added as break lines to a surface definition with the same type of data (supplementing data, for instance) as feature lines. Feature Lines in Civil 3D were originally based on the concepts and tools that many of us used in Land Desktop by grading with 3D polylines and then adding functionality that we could only wish for in LDT. I created a composite boundary from the 3D poly created above and your base feature line. Unlike 3D polylines, feature lines support arcs without tessellation. Use the Weed Vertices command to reduce the number of vertices on a feature line. See the follow up Surface Creation video. At my last job my boss would grade with feature lines (great!) and then extract all objects from the surface (ok) and then delete the surface and the grading group (why?!?!) and effectively leave me with a file that had 3d polylines as contours. The landscape area itself I have modelled as a standalone surface with a feature line around it that's offset approximately 1. John Armendariz, the CAD Coordinator at Kimley-Horn shares some method and practice about from moving from the classic Civil 3D Feature Line only workflow to a more Corridor centric workflow. Smoothing the feature line replaces tessellated line segments with arcs, and creating a dynamic link ensures that the feature line is updated with any Create a surface by defining a feature line and adding it to the surface definition as a breakline. The convergence plot flattens when the optimal grading has been achieved and the Optimizer can be ended. Grading group was not created successfully. Grips only indicate the PI Points (which is correct). Hi, I'm using Civil 3D 2010 (very new user) and have a question about grading. Next we need to create infill in the area of the enclosed feature lines. Description: Feature Line Elevation Relationship Lock: I would like to see, within a Civil 3D feature line, the ability to lock or hold a specific relationship between elevation points (vertices). grade to distance larger than the physical distance between them so that the each grading extends beyond the other feature line. The desired pad is an irregular shape, so a stepped offset will not work. Grading in Civil 3D involves creating proposed surfaces using various elements like points, feature lines, polylines, and gradings, and then comparing them to existing surfaces to determine volume differences. Civil 3D 2016 SP2. Traditionally, we generate alignments and pro Grading is a common workflow in Civil 3D, but did you know there was another way? In this webinar, we'll show you the difference between grading with feature Summary: Lock the relationship between points on a feature line. The coordinates of the corners in the image are the same but their However, poorly drawn Feature Lines leave designers with choppy surface contours, flat spots, and an urge to draw contours manually. You can also create a detached surface from a grading group, which is no longer associated with the gradings and does In this 30 min session, we walk through some grading examples in Civil 3D using Feature Lines. The class will also cover tips on how to use the grading tool to create the feature lines you’ll Does anyone know if there there is a way to grade a fill slope up from a feature line that will intersect a steeper slope? The feature line at the edge of the site is a little above the existing grade and the Grading objects only seem to be capable of grading a fill slope down till it intersects, not up. Type 0. #autodesk #c3d #civilengineering This time I am going to show you some examples using the combination of 3 important tools within Civil 3D, to accomplish both design and modelling in BIM Inf When using the Grading creation tool in Civil 3D, the "Create infill" operation doesn't create the filling in the area inside the feature line.

Thanks I am grading an urban sidewalk to the front of townhouses. As far as I can tell, you can't use a feature line as a corridor target. When I start the feature line and add my own elevation points in to set the levels I work my way About Feature Lines A feature line is a Civil 3D object that represents a three-dimensional polylinear element. This command will mark any overlapping locations found with AutoCAD points, placed on the layer _OVERLAPPING_SEGMENT_LOCATIONS. We’ll also discuss grading and feature line transitions, along with the “Quick Profile” function that can convert feature line transitions to alignments and profiles. Solved: Having trouble finding the default for the The surface modeling tools in Autodesk Civil 3D software include generic ones, such as points and breaklines, as well as purpose-built site grading tools for grading with feature lines and projected slopes. I'm about at my wits end trying to grade a site. I need to trim a graded feature line. The TIN lines pass over my face of curb and triangulate directly to the back of curb, which is causing contour mis-shaping. I thought C3D had a grading tool that would grade down to user input elevations along the feature line. This means that you can integrate corridor models and site grading models and have them react to each another. We need to grade from top of bank to the flowline of a ditch at a 3:1 slope. I have a feature line with varying elevations that I assigned to it from the EG surface. Next, create two surfaces from these grading, perform a cut fill, and create the zero elevation contour on the cut fill surface. I am using Civil 3D Grading to grade a lagoon / landfill closure.

I added several feature lines to create walkways throughout the site. Open the Corri-Door to On-Site Grading. Then you may calculate volumes comparing it to the existing surface. This will form a "cone" shaped surface Start with this command, which will check for overlapping alignments, feature lines, and lot lines in a Site. For reference, on C3D 2016 you can easily adjust a feature line that shares a common PI point on the same site. Delete PI and it turns into an arc. to argue that there was no difference in creating surfaces using polylines and points versus utilizing the feature line and grading group features of Civil 3d. I added Solved: I assigned elevations to a grading feature line from a surface, but there is way more points than I want. The problem occurs whenever you make any changes to a feature line that is assigned as a corridor baseline. The grading keeps stopping at one point along the feature line, leaving the rest of the feature line ungraded. The rest I'm grading with a combination of feature lines and grading objects. Feature line slopes can be adjusted to create proper drainage. The taxiway is being designed by others and we have to match into it. However, in 2018, that PI point is greyed out, which is should not be. Civil 3D. To be considered to be intersecting, the It sounds like you're using the grading objects to display the slopes in your production drawings.
