Selection Filter

 

 

 

 

In order to properly understand the Selection Filter, it is important to have a full understanding of geometry topology in GTS. Please read Basic Concept>Geometry Topology before proceeding to the Selection Filter.

To learn about various selection methods in GTS, please refer to Selection Method.

The Selection Filter enables the user to select an object on the basis of specified entities.

Depending on the working mode and the active command, the Selection Filter performs differently, and the user will have to select the entity type within the specially customized Selection Filter.

The working mode in terms of the Selection Filter is basically distinguished by whether a command is invoked or not.

  • Neutral Mode

The Neutral Mode is activated when the user has not yet invoked a command, and the Selection Filter has been set to default. In the Neutral Mode, the user can only select Datum, Shapes and Mesh Sets.

The Sub-Shape of a geometric entity and the individual nodes and elements cannot be selected. It is recommended to set the Selection Filter to Shape in the Neutral Mode.

  • Command Mode

The Command Mode is activated when the user invokes a specific command and the Selection Filter has been formed with the functions relevant to that command. The user can select any desired type including the Sub-Shape, individual node and element, depending on the command type.

The Selection Filter performs differently as per the relevant command. Make sure to check the Selection Filter before proceeding.

Select Solid.

Shell (H)

Select Shell.

Face (F)

Select Face.

Wire (W)

Select Wire.

Edge (E)

Select Edge.

Point (V)

Mesh

Mesh Set (M)

Select Mesh Set.
Select the Mesh Set itself or select nodes and/or elements that are included in the Mesh Set.

Node (N) (2)

Select Node.

Element (E) (2)

Select Element.

Node/Element (3)

Select Node and Element at the same time.
Include or exclude the nodes and elements in Mesh Set.

Element-Face (4)

Select 3D element face.
Apply the Face Pressure Load on the 3D element face.

Element-Edge (4)

Select 2D element edge.
Apply the Edge Pressure Load on the 2D element edge.

 
(1) The Sub-Shape of geometric entities will not be selected in the Neutral Mode.
(2) Only applicable in the Node and Element modifying functions.
(3) Only applicable in the Incl/Excl function in the Mesh Set Menu.
(4) Only applicable in the Load and Boundary Condition functions.

In the table, the letters in the parenthesis indicate the shortcut keys of the Selection Filter components. The shortcut keys only work when the focus is on the Work Window.

In the descriptions about selection buttons in the Online Manual, the items listed in the Selection Filter are written in blue letters in parenthesis.

Ex: Select Direction

Select the translation direction (Datum Axis, Datum Plane, Face or Edge): It indicates that the user can select the directions using the listed item (Datum Axis, Datum Plane, Face or Edge) in the Selection Filter.

 

The specified type in the Selection Filter will be displayed at the Cursor Tip on the screen.

The user can decide whether or not to display the Cursor Tip in the Display Option (View > Display Option).
