Adding to a Selection
To add to the existing selection hold down ⇧ Shift while right clicking. Clicking again on a selected item will de-select it.
As in Object mode, there is a unique active element, displayed in a lighter shade (in general, the last element selected). Depending on the tools used, this element might be very important!
Note that there is no option to choose what element to select between overlapping ones (like the AltRMB click in Object mode). However, if you are in solid, shaded, or textured viewport shading mode (not bounding box or wireframe), you will have a fourth button that looks like a cube, just right to the select mode ones.
When enabled, this limits your ability to select based on visible elements (as if the object was solid), and prevents you from accidentally selecting, moving, deleting or otherwise working on backside or hidden items.
Selecting Elements in a Region
Region selection allows you to select groups of elements within a 2D region in your 3D view. The region can be either a circle or rectangle. The circular region is only available in Edit mode. The rectangular region, or “Border Select”, is available in both Edit mode and Object mode.
What is selected using both these tools is affected by the Limit Selection to visible feature (available under the 3D viewport) in Solid Viewport Shading Mode.
Rectangular region (Border select)
Border Select is available in either Edit mode or Object mode. To activate the tool use the B. Use Border Select to select a group of objects by drawing a rectangle while holding down LMB . In doing this you will select all objects that lie within or touch this rectangle. If any object that was last active appears in the group it will become selected and active.
In (Start), Border Select has been activated and is indicated by showing a dotted cross-hair cursor. In (Selecting), the selection region is being chosen by drawing a rectangle with the LMB . The selection area is only covering the selection handles of three faces. Finally, by releasing LMB the selection is complete; see (Complete).
This selection tool is only available in Edit mode and can be activated with C. Once in this mode the cursor changes to a dashed cross-hair with a 2D circle surrounding it. The tool will operate on whatever the current select mode is. Clicking or dragging with the LMB , when elements are inside the circle, will cause those elements to be selected.
|Circle Region Select|
(Circle Region Select) is an example of selecting edges while in Edge Select Mode. As soon as an edge intersects the circle the edge becomes selected. The tool is interactive such that edges are selected while the circle region is being dragged with the LMB .
For Faces select mode, the circle must intersect the face indicators usually represented by small pixel squares; one at the center of each face.
Lasso select is similar to Border select in that you select objects based on a region, except Lasso is a hand-drawn region that generally forms a circular/rounded shaped form; kind of like a lasso.
Lasso is available in either Edit Mode or Object Mode. To activate the tool use the CtrlLMB while dragging. The one difference between Lasso and Border select is that in Object mode, Lasso only selects objects where the lasso region intersects the objects center.
(Lasso selection) is an example of using the Lasso select tool in Vertex Select Mode.
Additional Selection Tools
The select menu in edit mode contains additional tool for selecting components:
- (De)select All A
- Select all or none of the mesh components.
- Invert Selection CtrlI
- Selects all components that are not selected, and deselect currently selected components.
- More CtrlNum+
- Propagates selection by adding components that are adjacent to selected elements.
- Less CtrlNum-
- Deselects components that form the bounds of the current selection
