Inspect groups

Inspect groups command supports the systematic check of groups. It provides a list of groups from which you can select one group after the other.

The tool includes view settings that define CAD file views displaying the selected group in different view orientations. The selected element is automatically centered in these views. It becomes the active displayset and thus, it is displayed in views for which Points is set to Displayset only in the Display mode dialog. In addition, the tool allows the definition of up to four classification buttons for modifying the class of a group.
