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.
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).
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.
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.
