Master Civil 3D & QGIS: DWG to KML, DEM Elevation Extraction & CSV Export

Welcome to Part 1 of our comprehensive Infrastructure Design & Irrigation Network Masterclass! In this video, we kick off the series by bridging the gap between AutoCAD and QGIS. You will learn the exact workflow to convert your CAD alignments, extract real-world terrain elevations using OpenTopography DEM data, reproject your layers, and generate a precise XYZ attribute table ready for Civil 3D. Whether you're designing irrigation canals, farm service roads, or pipe networks, getting your base data right is everything. 📂 PRACTICE WITH ME: Download the raw sample files and practice datasets from our Google Drive link: https://drive.google.com/drive/folder... ⏱️ TIMESTAMPS: 0:00 - Introduction to the Masterclass 1:15 - Exporting CAD Alignments to KML/KMZ 3:30 - Importing KML Files into QGIS 6:00 - Downloading High-Resolution DEM via OpenTopography Plugin 9:45 - Reprojecting DEM & Spatial Data 12:30 - Creating Attribute Tables (X, Y, Z with High Precision) 16:00 - Exporting to Excel and Formatting as CSV for Civil 3D 19:15 - What's Next in Part 2? 🔗 RESOURCES & PLUGINS MENTIONED: QGIS Official Website: https://qgis.org/ OpenTopography Plugin details 👇 Don't forget to LIKE, SUBSCRIBE, and hit the notification bell 🔔 so you don't miss Part 2, where we dive deeper into accuracy audits and surface building! #Civil3D #QGIS #InfrastructureDesign #IrrigationDesign #LandSurveying #WaterGEMS
