Shortcut:
Shift-G
Select geometry that has similar certain properties to the ones selected, based on a threshold that can be set in tool properties after activating the tool. Tool options change depending on the 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.
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 mark used in UV texturing.
Sharpness
Selects all edges that have the same Sharp state as those already selected. Sharp is a mark used by the Edge Split Modifier.
Face Selection Mode:
Material
Selects all faces that use the same material as those already selected.
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 (added values of its edge lengths).
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.
Flat/Smooth
Selects all faces with similar face shading.
Freestyle Face Marks
Selects all faces with similar Freestyle Face Marks.
Compare
For quantitative properties, this property selects the type of comparison to between the two numerical values.
Equal:
Select items with the same value as the active item’s chosen property.
Greater:
Select items with a larger value as the active item’s chosen property.
Less:
Select items with a smaller value as the active item’s chosen property.
Threshold
For quantitative properties, this property controls how close the property’s values have to be in the comparison.
