Introduction

There are many ways to select elements, and it depends on what Mesh Select Mode you are in as to what selection tools are available. First we will go through these modes and after that a look is taken at basic selection tools.

Hotkey: Ctrl-Tab

Edit Mode selection buttons.

In Edit Mode there are three different selection modes. You can enter the different modes by selecting one of the three buttons in the header.

Vertices

In this mode vertices are drawn as points.

Selected vertices are drawn in orange, unselected vertices in black, and the active or last selected vertex in white.

Edges

In this mode the vertices are not drawn.

Instead the selected edges are drawn in orange, unselected edges black, and the active or last selected edge in white.

Faces

In this mode the faces are drawn with a selection point in the middle which is used for selecting a face.

Selected faces and their selection point are drawn in orange, unselected faces are drawn in black, and the active or last selected face is highlighted in white.

When using these buttons, you can make use of modifier keys, see: Switching Select Mode.

Almost all tools are available in all three mesh selection modes. So you can Rotate, Scale, Extrude, etc. in all modes. Of course rotating and scaling a single vertex will not do anything useful (without setting the pivot point to another location), so some tools are more or less applicable in some modes.

Switching Select Mode

When switching modes in an “ascendant” way (i.e. from simpler to more complex), from Vertices to Edges and from Edges to Faces, the selected parts will still be selected if they form a complete element in the new mode.

For example, if all four edges in a face are selected, switching from Edges mode to Faces mode will keep the face selected. All selected parts that do not form a complete set in the new mode will be unselected.

Hence, switching in a “descendant” way (i.e. from more complex to simpler), all elements defining the “high-level” element (like a face) will be selected (the four vertices or edges of a quadrangle, for example).

Multiple Selection Modes

By holding Shift-LMB when selecting a selection mode, you can enable multiple Selection Modes at once.

This allows you to quickly select Vertices/Edges/Faces, without first having to switch modes.

Expanding/Contracting Selection

By holding Ctrl when selecting a higher selection mode, all elements touching the current selection will be added, even if the selection does not form a complete higher element.

See Fig. Selection Modes. for examples of the different modes.

Or contracting the selection when switching to a lower mode.

Limit Selection to Visible

If you are in solid, shaded, or textured viewport shading mode (not bounding box or wireframe), you will have a fourth button in the header that looks like a cube, just right of the select mode ones.

When enabled, this limits your ability to view and select vertices occluded by the objects geometry (as if the object was solid). This is done by the viewport with depth buffer clipping.

Selection Tools

The select menu in edit mode contains tools for selecting components. These are described in more detail in the following pages.

Border Select

Enables a rectangular region for selection B.

Complete.

In Fig. Start., Border Select has been activated and is indicated by showing a dotted cross-hair cursor. In Fig. 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 Fig. Complete..

Circle Select

Enables a circular shaped region for selection C.

Before.

After.

Fig. 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.

If you want to deselect elements, hold MMB and begin clicking or dragging again.

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

Fig. Lasso selection. is an example of using the Lasso select tool in Vertex Select Mode.

More Tools

(De)select All A

Select all or none of the mesh components.

Inverse Ctrl-I

Selects all geometries that are not selected, and deselect currently selected components.

Random

Selects a random group of vertices, edges, or faces, based on a percentage value.

More Ctrl-NumpadPlus

Propagates selection by adding geometry that are adjacent to selected elements.

Less Ctrl-NumpadMinus

Deselects geometry that form the bounds of the current selection.
