Planes groups
Planes groups are a collection of one or more parallel planes saved to the Plan, Vertical, or Inclined folders in the Planes panel. In the Planes panel, you can select which plane you want to view in Graphics. Using the Parameter Set Editor, you can edit the properties of a single plane in the group.
The group name is the name of the folder in which the planes are stored. The full path to the directory must be less than 256 characters. You can use any letters, numbers, and characters except \ / : * ? " < > | in the group name.
