Deleting Scan Points in SCENE
Overview
Deleting unnecessary scan points can increase performance times and allow users to create a refined visual project with more accurate measurements. SCENE has several tools which can be used to select scan points for deletion.
NOTE: Unload scans before cleaning, to avoid black areas in shots.
NOTE: Cleaning in quick view will also generate black areas.
