Managing Units
Deleting Units
You can remove a custom unit by clicking the trashcan icon on the right side of the unit row.Editing Units
Units cannot be edited once created. If you need to change a unit’s definition, you must delete the existing unit and create a new one with the corrected definition.Version Control
Custom units are tracked by Davinci’s version control system.- Branching: Different branches can have different sets of custom units.
- Conflicts: If the same unit name is defined differently in two branches being merged, a conflict will occur.
- Resolution: You must resolve any unit conflicts in the Unit Settings view before you can create new units. The interface will display the conflicting definitions and allow you to choose the correct one.
