Similarly, when combining all codes "Datum," one could build the surface needed by the contractor to define the bottom of the road model. For example, if one is interested in creating a surface that combines all codes "Top" from the different subassemblies, one could visualize the top layer of the designed model. These codes can be used when defining corridor surfaces.

The most upper link (L1) in this subassembly has the code "Top" but also another code “Pave” attached. The link L1 has more than 1 code attached. The defined codes for each element are explained in the Civil 3D subassembly help. Each point, link, or shape element has one or more codes attached. The geometry of a subassembly is defined around points, links, and/or shapes. A subassembly can be a lane, a curb, the pedestrian sidewalk, a shoulder, a ditch, etc. Subassemblies (structural forming blocks) are elements that compose the geometry and substructure of the corridor model. The assembly is built from subassemblies. This can be done rather quickly if you have a good understanding on how a corridor model is built.Ī corridor model is built out of 3 components: a horizontal alignment, a profile (vertical profile geometry), and an assembly (typical design cross section, road description). This means each needs to be defined as a separate surface. This means that for a corridor model, a surface for each different material must be defined. Lanes, curbs, medians, shoulders, ditches, and slopes should all have their own material. Only one material can be applied per Civil 3D surface. Best practices for creating corridor surfaces However, you can also create a detached surface from a corridor. The surface will remain dynamically linked to the corridor, and any changes to the corridor definition are reflected in the surface definitions within the Prospector tab. These corridor surfaces are an output of a corridor model, which are created manually by extracting data from a set of link codes and corridor feature lines. The creation of these surfaces is a semi-automated task. These corridor surfaces are not created automatically when a corridor is created. Only TIN surfaces are currently supported in the Civil 3D plugin for MAGNET Modeler.Ĭorridor surfaces are created from a Civil 3D corridor (a 3D design model for something like a road, a railway model, or a pipe network trench). Within the group of surfaces, multiple subtypes are possible: They use points, point files, DEM data, existing AutoCAD objects, contours, breaklines, and boundaries. Surfaces are basic building blocks in AutoCAD Civil 3D, which are created from LandXML data, TIN (triangulated irregular network), and DEM (digital elevation model) files. The land surfaces are surfaces like an existing ground, a parking lot, etc. The two main types are (land) surfaces and corridor surfaces. Creating PDFsĪ Civil 3D drawing can contain different types of surfaces. With this box checked, only simple manholes (cylindrical) are shown in MAGNET Modeler. The Simple manholes check box only affects Civil 3D pipe networks. This is done by setting a value for one row, selecting multiple rows, and from the context sensitive menu selecting Set same material or Set same cut mode. With it you can check or uncheck a whole column and set the same material or cutting option for multiple rows at once. This dialog box also has a contextual sensitive menu. Rows can be moved by selecting a row and pressing the up or down arrows. If weld is selected, all other surfaces are welded to this surface.Ĭhecking the Locked box means the surface will not be cut or welded. You can modify the order with the up and down arrows. If cut is selected for a surface, then this surface cuts holes to all other surfaces that appear before the active surface in the list. You can select a material and cutting option for each group.Ĭutting only affects how surfaces relate to one another. Agriculture Smart Implements and Harvest.
