Group Operation
Select by Group
Ballance - Select by Virtools Group provides a feature to filter by Virtools grouping data.
The feature starts with 5 different selection strategies that match Blender's selection methods exactly (Set, Extend, Subtract, Invert, Intersect). Simply use it like a Blender selection. Then, select the name of the group you need and start a selection or filter.
About pattern selection
If you can, use the Subtract or Intersect modes whenever possible. Because this avoids analyzing too many objects. For example, selecting a general range first and then filtering using Intersect mode is more efficient than using Set mode directly.
Quick Grouping
The BBP plugin adds the ability to quickly group objects in 2 places. The first is the object context menu: you can select a series of objects and right click to find the quick grouping feature in the object context menu. Second is the Objects menu in Outline view: you can right-click on a selection of objects in the Outline view to find the quick grouping feature. Both menus are shown below.
Group into...
Groups the selection into the group of your choice.
Ungroup from...
Ungroups the selection from the group of your choice.
Clear All Groups
Clear all groups for the selection. You will be asked to confirm this before executing to avoid misbehavior.
