Civil3D Classic Course (Road, Tunnel & Arch Bridge)

Learn 2d/3d navigation in civil 3d with viewcube, navigation bar, and orbit to pan and rotate, manage world coordinates, and switch between shading, realistic visuals, and perspective or parallel views.

Copy the 2D drawings as a reference, clean unnecessary annotations, and set the geometric reference point for positioning the arch bridge. Prepare to model the arch as a compound curve.

Model abutments in 3d solid modelling by extruding sections, slicing, and combining via union and intersect, then mirror to create wings from the foundation.

Master 3d solid modelling of bridge bearings by shaping bearing plates, a seismic rubber gap, and grid-aligned extrusion and copies, with block creation for efficient placement.

Discover Civil 3D grading creation tools, using surfaces and targets to build cot and the field gradings, model backfill around abutments, and prepare for generating gradings in the next drawing.

The lecture covers creating second grading, its intersections with the lower grading, hiding and isolating surfaces to manage performance, and using 2d wireframe and 3d polyline to define trapezoid base.

Learn to create second foundation grading in Civil 3D, using a polyline and feature line, set two-meter benches and elevations, and cross the ground to a right foundation grading surface.

Create a tunnel portal in Civil3D, detailing bench elevations, base rectangle, feature lines, and grading tools, then check elevations and save progress.

Learn to grade to a surface using a feature line with a 1:1 slope, backfill to the abutment, and close holes by joining surfaces for a clean tunnel portal design.

Learn grading creation tools for tunnel portal backfill in Civil3D, building 3D polylines and surfaces, applying a 1:1 slope, and defining backfill boundaries with a minimum distance surface.

Apply grading creation tools to model the left abutment in Civil3D, using feature lines, elevations (79 and 84 107), four-meter offsets, and a -2% grade, then generate a detached surface.

Copy and refine the left abutment 3D polyline, convert it to a feature line, and apply a 1:1 grading to create the left foundation backfill surface.

Apply 3d rotate and sweep to form a temporary road corridor, defining the base and path from closed shapes, troubleshooting 3d orientation and preparing for grading.

Create the left road grading with its detached surface by turning a grade-bearing polyline into a feature line, applying grading with elevations and slopes, and finalizing a detached surface.

Adjust and customize longitudinal profile visuals by editing the view style, axis intervals, text color, and bands; manage templates, elevations, and station ranges to display accurate elevations.

Apply subassembly composer basics to create bridge deck shapes from polylines, add shapes and links, and troubleshoot missing links for corridor and tunnel sections.

Apply a pavement fill behind the right abutment, create region V2 around the tunnel and deck, and extract solids to render updated corridor geometry.

Create a solid bed for the tunnel portal by modeling a precise 3D polyline, verify elevations, align the centerline, then loft cross sections into a connected solid.

Create a basic highway lighting system in Civil3D by placing 3D light blocks along the project line and using a 3D polyline with realistic rendering.

Manage existing ground surfaces in Civil3D by using boundaries versus masking, preserve surface data for volume calculations, and keep organized left abutment grading and ditch transitions.

Rebuild the road corridor using the new subassembly, set the existing ground as target surface, and generate slopes and benches aligned to the project blue line.

Explain how the volume between cross sections is computed by averaging the cut areas (mean area) and multiplying by the distance (chainage), yielding cumulated volume and pavement insights.

Learn how to project 3D corridor components to the longitudinal profile and section views in Civil3D, optimize performance by hiding objects, and interpret the resulting 2D projections.
