Explicit Selection (Geometry Sequences)
Use an Explicit Selection node () to create the selection using the selection tools for individual geometry objects or geometric entities (boundaries, for example). To add this node, right-click the Geometry node and choose Selections>Explicit Selection.
Entities to Select
Based on space dimension, select a Geometric entity level: Object, Domain, Boundary, Edge, or Point for the geometry objects or entities to add to the selection list.
Select and add geometric entities in the Graphics window or using other selection methods. The selected items are highlighted in the Graphics window.
If Boundary (for 2D and 3D models) or Edge is selected, also select the Group by continuous tangent check box to extend the selection to all adjacent faces or edges that have continuous tangents (an angle less than the value in the Angular tolerance field) at their junctions to select all faces that make up a continuous sheet, for example. When the Group by continuous tangent check box is selected, set the tolerance on the continuity condition in the Angular tolerance field as the maximum angle between two faces or edges that are considered as having continuous tangents (a value between 0 and 180 degrees; the default value is 5 degrees).
Resulting Selection
By default, the Keep selection check box is selected. Clear the check box if you do not want the resulting selection to be available as a named selection in other nodes in the geometry sequence or other parts of the model tree. If the Keep selection check box is selected, you can also determine if the selection should appear in applicable settings for physics, materials, and other parts of the model tree outside of the geometry using the Show in physics list (or Show in instances if the selection is in a geometry part; Show in 3D in a plane geometry under a work plane in a 3D component). If the geometric entity level is not set to Object (any of Domain, Boundary, Edge, or Point), choose On (the default) or Off to show the selection in physics and other settings or not. If the geometric entity level is Object, choose one of All levels (that is, all entity levels), Object selection (in geometry parts only), Domain selection, Boundary selection, Edge selection (3D only), Point selection, or Off. For Show in physics, All levels is the default; for Show in instances, Object selection is the default.
Cumulative Selection
From the Contribute to list, choose an option. In addition to available Cumulative Selection nodes, None is always available from the list. To create a new Cumulative Selection, click New. Enter a Name in the New Cumulative Selection window. Click OK or press enter. This new cumulative selection is now available from any Contribute to list for a geometry selection.
Color
In this section, choose a color from the Color list for use with this selection. See Selection Colors.
