Project Alignment

Click the button in the right function panel of the scanning interface to enter the project alignment screen. This feature allows combining scanned data from multiple project files within the current project group into a complete 3D model, improving scanned data completeness.

Alignment Mode	Description	Alignment Mode	Description
Auto Feature Alignment	Automatically aligns based on model features, suitable for scanned data with rich geometric features or when markers cannot be applied.	Manual Feature Alignment	Aligns by manually selecting feature points on models. Use when auto feature alignment performs poorly.
By Markers	Automatically aligns based on markers on models, suitable for marked model data.	Manual Markers Alignment	Aligns by manually selecting markers on models. Use when By Markers performs poorly.
