3D Layout

The 3D Layout tool supports viewing and re-editing indoor scenes that had Smart Space Recognition enabled during model reconstruction.

Note:

  • 3D Layout is only available for indoor scenes that had Smart Space Recognition enabled during reconstruction
  • A 3D Layout license is required to use this feature

Opening & Activating

V2.2 Upgrade: Auto-Import — When importing LCC, the system automatically detects and associates the corresponding floor plan data. A floor plan child node appears automatically under the LCC node in the asset panel and activates on selection. No manual import needed.

  • If no floor plan data exists, LCC loads normally without error
  • If auto-association fails, a toast message appears: "Floor plan auto-association failed. You can bind it manually."

Manual Import (entry retained):

  1. File → Import → Floor plan file directory → Select the semantic-result folder in the project directory
  2. Click Confirm
  3. In Scene Mode, click 3D Layout in the toolbar to enter the interface
