▶ Site-Scale LOD and Data Preparation (~~4 min)
| **Clip:** 04 | **Duration:** ~4 min | **Recording segment:** ~18:00 → ~22:00 ---- Prerequisites ------------- :doc:`03-3dsc-lod-concept` Overview -------- Working at site scale with hundreds of objects. Bulk LOD switching lets you maintain all objects at a low-poly level and promote individual elements to full detail on demand. The 3DSC also imports CAD and GIS data, enabling geo-referenced multi-source integration inside Blender. .. figure:: /_static/screenshots/clip_04/0001_site_overview_low_lod.jpg :alt: Archaeological site overview with all objects at low LOD. :width: 90% Archaeological site overview with all objects at low LOD. Key Concepts ------------ - Bulk LOD switching: set all scene objects to low-poly with a single operation. - Promote individual elements to high-detail when inspecting specific features. - CAD/GIS import: bring geo-referenced data directly into the 3D scene. - The approach scales from a single artefact to thousands of square metres.

Try It Yourself --------------- Load the Great Temple scene from the playground dataset, set all objects to LOD Level 1, then promote a single column to LOD Level 4. .. note:: A video walkthrough for this tutorial will be available on the Extended Matrix YouTube channel. .. seealso:: :doc:`From 3D Models to Knowledge: Proxies
