Instance
An instance defines the area to be processed and includes all objects captured in the scan. The scanned area can be cropped in the next steps. A clear name (e.g. following internal naming conventions) and location ensure unambiguous identification throughout the process.
Coordinate System
After processing, the mesh objects generated by RIIICO retain the exact coordinates captured in your scan. Please ensure your scanning data uses a coordinate system that matches your requirements, and indicate this by selecting the corresponding option, as it affects accuracy and alignment.
Site coordinate system
Site coordinate system
A Site Coordinate System (SCS) is a fixed, real-world reference for your building or site. It ensures that all scans from the same location share the same spatial origin and orientation.
Choosing SCS allows you to:
avoid rotation, drift or distortion
be able to consistently align multiple scans
align scans with existing CAD or BIM systems, or integrate with GIS data
work accurately across large areas or multiple floors
update scans regularly and detect changes without manual alignment
Provides the highest spatial accuracy; generally recommended.
No coordinate system alignment
No coordinate system alignment
Choose no coordinate system alignment if:
a site coordinate system is unavailable, outdated, or incorrect
working with a standalone area
no cross-system alignment or precise geographic reference is needed
