Selecting and Clearing Selection of Geometric Entities

Table 6-3: Different ways to select geometric entities
Task	Action
Select any level of geometry:	In The Graphics Window, click the geometric entity to add it to an active selection list in the current node’s Settings window. Open The Selection List Window and click entity numbers (or names); then click the Add to Selection button () to add it to an active selection list in the current node’s Settings window. You can also add an entity to an active selection list in the current node’s Settings window by double-clicking it or by right-clicking it and selecting Add to Selection.
Select all parts of the geometry:	In most Settings windows’ selection sections, the option to select All domains, All boundaries, All edges, or All points adds all geometric entities of that type to the list of selected entities. The selected items are highlighted in the Graphics window and all entities are kept selected, even if the geometry changes. Open The Selection List Window and use the Shift or Ctrl keys to select all of the entity names (or numbers). You can also click the main geometry node to select all entities that the node includes. Then click the Add to Selection button () to add it to an active selection list in the current node’s Settings window. In the Graphics window, click the Select All button ( in 3D), or click outside of the geometry or press Ctrl+A to select all entities. For Windows users, a Select All button is available on a customized Quick Access Toolbar. For Mac and Linux users, from the main menu select Edit>Select All. This highlights and selects all entities but does not confirm the selection or lock it if the model changes.
Clear the selection of all parts of the geometry not added to a selection list:	In the Graphics window, click the Clear Selection button (), or click outside of the geometry or press Ctrl+D to clear all selected entities. For Windows users, a Clear Selection button is available on a customized Quick Access Toolbar. For Mac and Linux users, from the main menu select Edit>Clear Selection.
Move, rotate, and then select (3D only):	Multiple mouse actions can be done together. For example, use the mouse to rotate or move the object left and right to locate the geometric entity to add to a selection list; then click to add to the selection.
Lock the geometry selection settings during selection:	In the Graphics window, click the Select None button (). Then no clicks in the graphics highlight or select any geometric entities, which makes it possible to move and rotate the geometry freely.
Add to Selection :	In the Graphics window, click a red highlighted entity to add it and make it blue. Or select one or more geometric entities and click the Add to Selection button. In the Selection List window, select the entity names to add, and click the Add to Selection button. You can also paste selections from a file. See Copying and Pasting Selection Lists for information. For user-defined selections this action must be completed on the selection page. See Create an Explicit Selection from the Selection List Window for information.
Select Box: 3D 2D 1D	To select multiple parts of the geometry, in the Graphics window, click the Select Box button; then click and hold the left mouse button to draw a square over the geometry.

In the Selection List window, use the Shift or Ctrl keys to select the entity names (or numbers). Click the Add to Selection button.
Deselect Box: 3D 2D 1D	To deselect multiple parts of the geometry, in the Graphics window, click the Deselect Box button; then click and hold the left mouse button to draw a square over the geometry.

Select Boundaries: 3D 2D 1D	In the Graphics window, click the Select Boundaries button. Click to select the boundary and add it to the selection list. In the Settings window, select Boundary from a geometry entity level selection list and then click in the Graphics window. Only boundaries are highlighted.
Select Edges :	In the Graphics window, click the Select Edges button. Click to select the edge and add it to the selection list. In the Settings window, select Edge from a geometry entity level selection list and then click in the Graphics window. Only edges are highlighted.
Select Points: 3D 2D	In the Graphics window, click the Select Points button. Click to select the point and add it to the selection list. In the Settings window, select Point from a geometry entity level selection list and then click in the Graphics window. Only points are highlighted.
Select None: 3D 2D 1D	In the Graphics window, click the Select None button to turn off all selections so that you can click in the Graphics window to move or rotate the geometry, for example, without adding any object or entity to a selection.
