Advanced Selection

The select menu in edit mode contains additional tool for selecting components:

Mirror
Select mesh items at the mirrored location.
Linked CtrlL
Selects all components that are connected to the current selection.
Select Random
Selects a random group of vertices, edges, or faces, based on a percentage value.
Checker Deselect
Deselect alternating faces, to create a checker like pattern.
Select Sharp Edges
This option will select all edges that are between two faces forming an angle less than a given value, which is asked you via a small pop-up dialog. The lower is this angle limit, the sharper will be the selected edges. At 180°, all “manifold” (see below) edges will be selected.
Linked Flat Faces (Ctrl⇧ ShiftAltF)
Select connected faces based on a threshold of the angle between them. This is useful for selecting faces that are planar.
Select Non Manifold (Ctrl⇧ ShiftAltM)
Selects vertices that are not completely bound by geometry, including border edges, floating edges, and orphan vertices. Only available in Vertex and Edge mode.
Interior Faces
Select faces where all edges have more than 2 faces.
Side of Active
Selects all data on the mesh on a single axis
Select Faces by Sides
Selects all faces that have a specified number of edges.
Loose Geometry
Select all vertices or edges that do not form part of a face.

Select Similar

Mode: Edit mode

Hotkey: ⇧ ShiftG

Menu: Select » Similar...

Select components that have similar attributes to the ones selected, based on a threshold that can be set in tool properties after activating the tool. Tool options adjust to the active selection mode
Vertex Selection Mode
Normal
Selects all vertices that have normals pointing in similar directions to those currently selected.
Amount of Adjacent Faces
Selects all vertices that have the same number of faces connected to them.
Vertex Groups
Selects all vertices in the same vertex group.
Amount of connecting edges
Selects all vertices that have the same number of edges connected to them.


Edge Selection Mode
Length
Selects all edges that have a similar length as those already selected.
Direction
Selects all edges that have a similar direction (angle) as those already selected.
Amount of Faces Around an Edge
Selects all edges that belong to the same number of faces.
Face Angles
Selects all edges that are between two faces forming a similar angle, as with those already selected.
Crease
Selects all edges that have a similar Crease value as those already selected. The Crease value is a setting used by the Subsurf Modifier.
Bevel
Selects all edges that have the same Bevel Weight as those already selected.
Seam
Selects all edges that have the same Seam state as those already selected. Seam is a true/false setting used in UV-texturing.
Sharpness
Selects all edges that have the same Sharp state as those already selected. Sharp is a true/false setting (a flag) used by the EdgeSplit Modifier.


Face Selection Mode
Material
Selects all faces that use the same material as those already selected.
Image
Selects all faces that use the same UV-texture as those already selected (see UV-texturing pages).
Area
Selects all faces that have a similar area as those already selected.
Polygon Sides
Selects all faces that have the same number of edges.
Perimeter
Selects all faces that have a similar perimeter as those already selected.
Normal
Selects all faces that have a similar normal as those selected. This is a way to select faces that have the same orientation (angle).
Co-planar
Selects all faces that are (nearly) in the same plane as those selected.


Selecting Loops

You can easily select loops of components:

Edge Loops and Vertex Loops

Mode: Edit mode → Vertex or Edge select mode

Hotkey: AltRMB Template-RMB.png or CtrlEEdge Loop

Menu: Select » Edge Loop or Mesh » Edges » Edge Loop

Holding Alt while selecting an edge selects a loop of edges that are connected in a line end to end, passing through the edge under the mouse pointer. Holding Alt⇧ Shift while clicking adds to the current selection.

Edge loops can also be selected based on an existing edge selection, using either Select » Edge Loop, or the Edge Loop Select option of the Edge Specials menu (CtrlE).

Vertex mode
In Vertex select mode, you can also select edge loops, by using the same hotkeys, and clicking on the edges (not on the vertices).


Longitudinal and latitudinal edge loops.

The left sphere shows an edge that was selected longitudinally. Notice how the loop is open. This is because the algorithm hit the vertices at the poles and terminated because the vertices at the pole connect to more than four edges. However, the right sphere shows an edge that was selected latitudinally and has formed a closed loop. This is because the algorithm hit the first edge that it started with.

Face Loops

Mode: Edit mode → Face or Vertex select modes

Hotkey: AltRMB Template-RMB.png

In face select mode, holding Alt while selecting an edge selects a loop of faces that are connected in a line end to end, along their opposite edges.

In vertex select mode, the same can be accomplished by using CtrlAlt to select an edge, which selects the face loop implicitly.

Face loop selection.

This face loop was selected by clicking with AltRMB Template-RMB.png on an edge, in face select mode. The loop extends perpendicular from the edge that was selected.

Alt versus CtrlAlt in vertex select mode.

A face loop can also be selected in Vertex select mode. Technically CtrlAltRMB Template-RMB.png will select an Edge Ring, however in Vertex select mode, selecting an Edge Ring implicitly selects a Face Loop since selecting opposite edges of a face implicitly selects the entire face.

Edge Ring

Mode: Edit mode → Edge select mode

Hotkey: CtrlAltRMB Template-RMB.png or CtrlESelect » Edge Ring

Menu: Select » Edge Ring or Mesh » Edges » Edge Ring

In Edge select mode, holding CtrlAlt while selecting an edge selects a sequence of edges that are not connected, but on opposite sides to each other continuing along a face loop.

As with edge loops, you can also select edge rings based on current selection, using either Select » Edge Ring, or the Edge Ring Select option of the Edge Specials menu (CtrlE).

Vertex mode
In Vertex select mode, you can use the same hotkeys when clicking on the edges (not on the vertices), but this will directly select the corresponding face loop…


A selected edge loop, and a selected edge ring.

In (A selected edge loop, and a selected edge ring), the same edge was clicked on but two different “groups of edges” were selected, based on the different commands. One is based on edges during computation and the other is based on faces.

Path Selection

Mode: Edit mode

Hotkey: CtrlRMB Template-RMB.png and the menu item SelectShortest Path

Select a face or vertex path with CtrlRMB Template-RMB.png

Selects all geometry along the shortest path from the active vertex/edge/face to the one which was selected.

Loop Inner-Region

Mode: Edit mode → Edge select mode

Hotkey: CtrlESelect Loop Inner-Region

Menu: Select » Select Loop Inner-Region or Mesh » Edges » Select Loop Inner-Region

Select Loop Inner-Region selects all edges that are inside a closed loop of edges. While it is possible to use this operator in Vertex and Face selection modes, results may be unexpected. Note that if the selected loop of edges is not closed, then all connected edges on the mesh will be considered inside the loop.

Loop to Region.
This tool handles multiple loops fine, as you can see.
This tool handles “holes” just fine as well.

Boundary Loop

Mode: Edit mode → Edge select mode

Hotkey: CtrlESelect Boundary Loop

Menu: Select » Select Boundary Loop or Mesh » Edges » Select Boundary Loop

Select Boundary Loop is the “logical inverse” of Select Loop Inner-Region, based on all regions currently selected, it selects only the edges at the border of these regions. It can operate in any select mode, but will always switch to Edge select mode when run.

All this is much more simple to illustrates with examples:

Select Boundary Loop does the opposite and forces into Edge Select Mode
