If you are working with extremely large Lidar data, consider increasing your "Sample every" values. They point out the issues of the data and point out the advantage of quality work. Apply a profile design check set3m 15s. Better triangle density and smoother contours on a gut check let us know this will do the job. We can fix them by adding more data. Create and apply point groups7m 59s. As you can see, the numbers aren't quite as good here. Breaklines represent linear features of a site such as edges of pavements, sidewalks, shoulders, curbs, or top of banks. Apply an Alignment Design criteria file3m 6s. A boundary does alter the data and/or visual output of a surface depending on boundary type. If you look at the numbers, you can see that over 96% of the surfaces are within 0. The other option in isolating surface areas is to utilize a boundary instead of a mask. Edit parcels with grips2m 59s.
How to use the Simplify Surface command to weed out unnecessary data without compromising the integrity of your model. On the Insert tab of the ribbon, you can simply attach the ReCap file. Alternatively, you could remove the Snapshot to have the FG surface reflect the needed view. Edit feature lines with Elevation commands7m 54s. There are several approaches to handle this; some of the key approaches have been detailed below: - Volume Surface: Create a volume surface between Base of Platform and EG, less Topsoil. When you have utilities to install, structure elevations shown as center. Linking contours with break lines can solve some issues. The Civil Side: Managing Large Surface Data. This is the fastest way to get a surface that was created in another program into Civil 3D and it also eliminates the possibility of errors being introduced during the process of rebuilding the surface. When a pasted surface was moved up the Operations List above a Snapshot, the edit disappeared. Did I get something wrong? Now that we have the data in Civil 3D we need to generate a surface representing the existing ground conditions. Right-Click anywhere in the Drawing Area and click Select Similar. All contours are now selected.
Building pads benefit from a few quick lines to make a fence around the single elevation. Any time I go to the effort of drawing 3D lines, I make sure all the elements I am connecting are correct. Contours and user-defined contours. Create a pressure network from objects4m 47s.
Example of toggling between surface boundaries: These are examples of the Civil 3D tools available solely within the surface controls. Show boundaries display areas inside hide boundaries, as with the case of courtyards enclosed by a building. You can add more than one data clip boundary to a surface. To complete this method, simply perfom the following steps: - Create a surface for the EG from the survey data. And if you are using it on your projects, what do you use it for? Draw a gravity network in Profile view4m 38s. When you define a mask as an outside type, the portion of the surface residing outside the defined area is hidden. If we could take only the cut and isolate it from the fill between those two surfaces, we could get the proposed formation by combining the EG less Topsoil surface with the cut obtained as previously described.
To start the planar surface command, you can type PLANESURF, or just use the short version and type PLA, and then press Enter. The course includes the full civil 3D essentials book and practice files. Use transparent commands3m 31s. My hat's off to you, most jobs do not get enough warning to make them pretty from the start. You can see the new ground, and the AEC elements displayed along it. The layer has points for all the surfaces in the DWG file. This is the exception and not the rule. 1′ increments) but I lumped everything beyond 0. To show how to isolate specific areas. It is very similar to the contours analysis, but rather than showing lines (contours), it shows fully shaded areas for each interval. Apply a linework code set4m 38s. Create alignments using the Alignment Creation tools6m 26s. Data Shortcuts have made utilizing large files incredibly easy, but sometimes surface files can still bog down a drawing when refreshing line work and data.
Add a layer to the scene and set a definition query. Create a grading group for the platform, selecting EG less Topsoil as the target surface. In addition, when defining a mask as Render Only, the display of the surface is not masked, but when the surface is rendered, the render material pattern is displayed. However, the person supplying you with the drawing may be unable, or unwilling, to export the surface as a LandXML file for you. So the name of the style suggests that we're probably going to see contours when we use this style. A little concerning was the fact that over 6. Click <
Understand pressure networks2m 6s. Understanding grading objects2m 35s. Contours and user-defined contours are virtually the same, with the only difference that they are placed in different layers, allowing you to have a main display setting for major and minor contours, plus an analysis of user-defined contours for a set of specific elevations, for example. Boundaries also can only be turned on and off in the surface file.
