#12dModel Super Alignment from Non-3D Data | Intersection Point Method Tutorial #TechForum

In this 12d Model Tech Forum session, Rod Burns demonstrates how to create accurate super alignment geometry from non-3D source data using the Intersection Point (IP) method. This practical workflow is ideal for civil designers and surveyors working with PDF plans, long sections, or tabulated data where direct 3D geometry is not available. 🔧 WHAT YOU’LL LEARN: • How to build horizontal and vertical geometry from non-3D inputs • Using the Intersection Point (IP) method in 12d Model • Importing CSV point data to streamline geometry creation • Drafting arcs using two points and radius for quick construction • Creating and editing super alignments efficiently • Applying radii, grades, and vertical curves (parabolas) • Using tools like the Tangent Wizard to resolve geometry issues • Validating your design with long section plots 📊 WORKFLOW OVERVIEW: Starting from spreadsheet data (Easting, Northing, radii), Rod shows how to import and construct tangent points, generate arcs, snap to IPs, and build a complete super alignment string with both horizontal and vertical geometry. 📐 KEY INSIGHT: Even complex geometry—such as roundabout kerb returns with multiple arcs—can be efficiently created using the IP method without relying solely on element-based design. 👷 WHO THIS IS FOR: • Civil engineers and designers • Surveyors working from 2D plans or PDFs • 12d Model users building alignments and long sections • Anyone looking to improve efficiency in geometry creation 💡 PRO TIP: Use spreadsheet preparation and naming conventions to significantly speed up alignment creation and reduce manual input errors. 📌 FINAL STEP: Always validate your geometry by generating a long section plot and checking against source documentation. 💬 Need help or want to go deeper?
