Updating Groups

This task shows how to:

• Update a group you just have created or you have edited or a group under a mesh part.
• Update all groups belonging to a same Groups set.

• The Update Group contextual menu is available both in the Generative Structural Analysis workbench and in the Advanced Meshing Tools workbench for a group created under a Groups set and for a group created under a mesh part.
• The Update All Groups contextual menu is not available for groups created under a mesh part.
  This contextual menu is only available for groups belonging to a Groups set (both in the Generative Structural Analysis workbench and in the Advanced Meshing Tools workbench).
• A group set will not be updated even if you update locally all the groups (updating locally groups means that you update one by one all the groups of this set using the Update Group contextual menu).
  To update a group set, you have to use the Update All Groups contextual menu.
