c3d-corridors

What problem does it solve?

Corridor-based automation and modeling for Civil 3D projects, enabling programmatic creation, inspection, and management of corridors including baselines, regions, assemblies, subassemblies, and corridor surfaces to streamline design workflows.

Core Features & Use Cases

• Create and modify corridors by adding baselines, regions, and assemblies, and by configuring surface outputs for finished road corridors.
• Read, update, and organize baselines and regions (split, merge, remove) and manage region-level targets and solids exports.
• Work with corridor surfaces: create, render,boundaries, masks, elevations sampling, and expose surface properties for design visualization.
• Manage assemblies and subassemblies: create, copy, mirror, import, and apply subassemblies along corridors, including applied assemblies with calculated shapes, links, and points.
• Code-set style integration and cross-references: set corridor code styles, reference alignments and profiles, and access related developer guides and data structures.
• Typical workflow: model a full corridor from alignment and profile to finished surface, then iterate revisions and export geometry for further analysis.

Quick Start

Create a new corridor named "Main Road" with a centerline baseline and a corresponding profile, add a region with an assembly, rebuild the corridor, and export solids for use in downstream analysis.
