Basic roadway design civil 3D

🛣️ Basic Roadway Design in Civil 3D | Step-by-Step Beginner Tutorial In this tutorial I walk you through a complete roadway design workflow in AutoCAD Civil 3D — from raw survey data all the way to a finished 3D corridor model. This is the exact process used on real infrastructure projects in Australia. ✅ What you'll learn: → Import survey point data (CSV/PNEZD format) and build a TIN surface → Create a horizontal alignment with tangents and curves (R = 200m at 60 km/h) → Design a vertical profile — grades, K-values, and Austroads standards → Build an assembly: lane, kerb & gutter, and footpath (metric) → Generate a full 3D corridor model and extract cross-sections ⏱️ Chapters: 00:00 Intro 00:35 Project setup and coordinate system (GDA2020 MGA Zone 55) 00:55 Importing survey data and creating a surface 02:50 Creating the horizontal alignment 04:10 Designing the vertical profile 06:35 Building the assembly (typical cross-section) 08:50 Creating the corridor model 09:45 Recap and outro 📁 Project files (CSV point data): [https://drive.google.com/file/d/1FQmD... ] 🔗 Watch next: → Cut and Fill Volume Calculation in Civil 3D → Drainage Layout in Civil 3D → Create Intersection in Civil 3D → Creating Sample Lines and Cross-Sections 📌 Software used: AutoCAD Civil 3D 2023 (workflow applies to 2020–2025) 📐 Australian Standards referenced: → Austroads Guide to Road Design (AGRD) Part 3 — Horizontal Alignment → Austroads Guide to Road Design (AGRD) Part 3A — Vertical Alignment → GDA2020 / MGA Zone 55 coordinate system 👤 About Er.AD Learning: I'm Dilip — a Graduate Civil Engineer (GradIEAust) based in Canberra, ACT.
