Selecting Using a Filter

This task shows you how to manage and customize the sub-geometry selection in order to avoid any ambiguity.
  The User Selection Filter toolbar is divided into two sections:
  • The first section lets you filter elements according to their type:
    • Point Type
    • Curve Type
    • Surface Type
    • Volume Type
  • The second section lets you filter elements according to their mode:
    • Feature Element Type selects the whole feature whether it is a sketch, product, pad, join, etc.
    • Geometrical Element Type enables to sub-elements of a feature such as faces, edges or vertices.
  By default, all the icons are deactivated which means that no filter is applied but you can restrict the selection to specific element types by clicking the corresponding icons.
  Bear in mind that:
  • If you deselect a type, it cannot be selected in the geometry anymore unless all other types are deselected.
  • If you deselect a mode, it cannot be selected anymore for each active type unless other modes are deselected.
  • It is not possible to activate both filter modes simultaneously (it does not make sense anyway). Only two states are available: either Feature Element Filter or Geometrical Element Filter is activated or both modes are deactivated.
  By selecting Assembly Design commands, some filtering types turn disabled because they are inconsistent according to the elements allowed in the command.
  • You need to activate the User Selection Filter toolbar by selecting the View -> Toolbars command and clicking User Selection Filter.
  • Open the Assembly_01.CATProduct document.
