Work With Civil 3D Corridors

Create an assembly and its subassemblies and attach alignment and profile. Learn about point codes, links, and shapes in subassemblies; see how lanes and super elevation influence material calculation.

Learn to use code set styles in Civil 3D corridors to label subassembly points, adjust crown, work, and other point codes, and apply label styles through assembly properties.

Create your first corridor in Civil 3D by assembling two 3.6-meter lanes, attaching to the alignment, and setting the profile and frequencies, then rebuild or enable automatic rebuild.

Develop a Civil 3D corridor by attaching shoulder subassemblies on both sides and adding a daylight subassembly, then use section editor and target surface to verify and rebuild.

Learn to create a corridor from a feature line, using it as the baseline, adjust frequency stations and along curvature, select an assembly, and rebuild the corridor.

Learn to set corridor frequencies in Civil 3D, adjusting the interval along tangents and spirals, and add manual frequency lines such as station 45 to refine assembly placement.

Learn how target mapping enables width targets in Civil 3D corridors, applying left lane edge and shoulder targets with polyline and offset alignments to drive a single assembly.

Explore how to use the corridor section editor in Civil 3D to edit parameters, view cross sections, adjust baselines, stations, viewport configurations, and display options for precise corridor modeling.

Apply conditional cut-and-fill assemblies in Civil 3D corridors by setting height-based slope rules for left and right sides, configure daylight targets, and verify with the corridor section editor.

Learn to set up conditional horizontal targets in Civil 3D corridors, defining target found and target not found conditions to switch assemblies and lanes automatically.

Learn to use match parameters in Civil 3D corridors to propagate targets across regions, set width targets, and apply targets through corridor properties.

Extract feature lines from a corridor to measure drain and berm drain lengths, and leverage conditional assemblies and styles to support surfaces and quantity calculations.

Learn to add material area fill styles to Civil 3D corridors by configuring top materials, subassembly properties, and code style settings, and preview the results on the corridor.

Learn to extract corridor solids from a Civil 3D corridor, selecting regions and sub base shapes, for 3D modeling and volume calculations, with options for dynamic linking and layer naming.

Learn to create points from a Civil 3D corridor by generating code points from corridor at every frequency location on both sides, using the IPS point group.

Learn to create corridor reports in Civil 3D using the toolbox and report manager, selecting the corridor, centerline, and sample lines to generate IPS data and a report.
