In this short Archicad tutorial, you’ll learn how to insert a building into a 3D terrain using Solid Element Operations. The terrain file comes from TopoExport.com, your go-to source for accurate 3D topographic data for BIM and site modeling.br br This workflow includes:br • Grouping building elements for clean manipulationbr • Using the terrain mesh as a target in SEObr • Subtracting terrain volume to embed the building correctlybr • Visualizing the result with a section cutbr br This technique is perfect for architects and designers looking to create precise, site-specific models with true-to-slope building integration.
