UI Overview


The Combine Selection Group Dialog found in the Right Mouse click menu of the Selection Group Palette, allows you to combine any number of Selection Groups into a new Group,

 that contains all selected elements from the originally combined Groups.


Pay attention to tooltips. Nearly every function has extensive tooltips listing functionality and hotkeys



The Search and Filter Bar (1)  controls what Selection Groups are displayed in the List View (4). 

Due to the comprehensive nature of the available Filter Options, these are covered in a separate topic here.


Filtering Options are explained more in-depth here /Selection Groups/Combine Selection Groups/Filtering


The Filter Bar is separated in the main search bar, allowing you to do word and expression searches, and the global filter buttons allowing you to set specific filters e.g. to only search inside of Face Groups, only visible selection Groups,

apply Path Filtering etc.



The Activation Quick Actions (2) allow you to modify the "Combine" Checkboxes in the List View (4). Only Selection Groups with a Combine checkmark will be part of the combining process. 
All Activation Options only apply to the displayed Selection Groups in the List View (4). Selection Groups that are hidden by filters are ignored
