The Classifier window displays the list of created classes (the Classes group) and the classification structure as a tree-like diagram. The root folder of the tree represents the entire classifier.

​
Classification tree structure

Each node in the tree corresponds to a classification stage. A node contains a group identifier element (named Id by default) and nested nodes. The nesting depth is not limited.

​
Move and copy classification stages

You can rearrange stages directly in the tree using one of the following actions:
  • Move a stage by dragging and dropping it.
  • Copy a stage by holding Ctrl while you drag and drop it.
