1. Select the Select tool from the Edit ribbon group.

2. Mouse over the vertices, edges, faces in the workspace to preview the selectable items in your design.

   If multiple objects occur at your cursor location, use the scroll wheel or arrow keys to preview each one.

   Click to select a vertex, edge, or face in 3D; click to select a line or point in 2D.

   To select:	Do this:
   All the edges around a face or closed loop	Double-click an edge or line. Double-click again to select the next loop of edges. Repeat as necessary. You can also right-click the edge or line and choose one of the loop options in the Select menu. When you repeatedly double-click outside surface edges, the selection cycles through open loop, tangent chain, and face loop, then repeats through that list.
   All tangent faces	Double-click a face. (Tangent faces are created by rounds or when edges are drawn on a face.)
   Contiguous edges or faces	Click one face or edge, then Shift+click another face or edge to select all the faces or edges between the two.
   The sides (but not the top and bottom) of a solid	Triple-click the solid and Ctrl+click the top and bottom to remove them from the selection.
   A solid or surface body	Triple-click the solid, or right-click on the solid and select Select > Body.
   An entire sketch	Triple-click the sketch.
   A component	Right-click on the component and select Select > Component. This option is available only when you right-click an object within the active component.
   All objects of same type as selected object	Select an object and press Ctrl+A.
   All the objects in the active component (except layout surfaces)	Click Select All in the Select tool menu, or right-click and select Select > Select All from the context menu. The types of objects selected depend on whether you are in Sketch, Section, or 3D mode.
   Layout surfaces	Click the object in the Structure tree.
   Anything within a selection box	See Box-selecting.
   A lightweight component	Check the Lightweight Components box in the Options panel. Then right-click and select Select > Component.
   The inverse of the current selection (in the active component)	Right-click a selected object and select Select > Inverse Selection.
   A protrusion	Right-click on a protrusion and select Select > Protrusion.
   A depression	Right-click inside a depression and select Select > Depression.
   One member of a pattern	Right-click a pattern member and select Select > Pattern Member.
   All members of a pattern	Right-click a pattern member and select Select > All Pattern Members.
   Anything partially in a selection box	Click and drag from the lower right to upper left when drawing a selection box.
   The inverse of the current box selection	Press and hold Ctrl while box-selecting to toggle the selected state of the objects within the selection.
   Objects that are behind other objects ("query selection")	Hold the Ctrl key and turn the mouse wheel.

   If any object was part of a group selection used to perform an action, the other parts of the group are highlighted when that object is selected. Click again to select the entire highlighted group.

   When selecting within a view on a drawing sheet, you can only select those objects that are on the cross-section plane, or that are within the boundary of a detail view. Box selecting in Sketch mode selects only sketch lines. Box-selecting in Section mode selects only section lines.

   (Optional) Ctrl+click and Shift+click to add or remove items from the selection set.

   Ctrl+click to add or remove one item from the selection set. Shift+click to add everything between your first click and the Shift+click to the selection. You can add or remove items both in the workspace and on the Structure tree. You can also press Ctrl and drag to add the items within the selection box to the selection.

   (Optional) Alt+click to create a secondary selection set.

   Hold down the Alt key while performing any of the other selection techniques (double-click, triple-click, Ctrl, Shift) to create the second selection set. Alternate selections are shown in blue, and are used to guide the actions of the Pull and Move tools.

Click any empty space in the Design window or select Clear Selection from the Select tool menu.

Click Revert Selection in the status bar to go back to your previous selection.

This tool is especially useful when you accidentally clear your selection or add the wrong object and want to go back to your previous selection. You can find this tool next to the Selection filter in the status bar, as shown below.

• Coincident objects: Objects often appear at the same location in 2D, such as a vertex and end point of a line that are located at the same point in space. When selecting, check that you have selected the correct object by turning the mouse wheel without moving the mouse.
• Edge shared by two surfaces or solids: Mousing over the edge shades the face that will be affected by an action to the edge if you select it. Turn the mouse wheel to switch between the two faces.
• Vertex shared between two edges: Mousing over a vertex shades the edge that will be affected by an action to the vertex if you select it. Turn the mouse wheel to switch between the edges.
• Face of a solid when only the edge is displayed (such as in a drawing sheet view): You can select the face by turning the mouse wheel. The edge becomes a slightly thicker line when the face is highlighted.
• Edge loops: If Select edge loops using the mouse scroll wheel is selected in the Advanced DesignSpark Mechanical options, scrolling through edge loop choices pre-highlights the selection. Click on the pre-highlighted edge loop to select it.

  

The up and down arrow keys work the same as the mouse wheel. Mouse over the element you want to select, and press the up or down arrow keys to "scroll" through the possible selections. This is useful if you are on a laptop or when you use a mouse that doesn't have a scroll wheel.
