Common Modeling Commands
Grab: Moves the selection in 3D space. Works for Vertices, Edges, and Faces

Rotate: Rotates the selection in 3D space. Works for Vertices, Edges, and Faces

Scale: Grows or shrinks the selection in 3D space. Works for Vertices, Edges, and Faces

Loop Cut: Divides existing geometry into equal segments along a chain of 4-sided faces (known as “quads”). You can scroll the mouse wheel to increase or decrease the number of divisions. Works on unfilled edges.

Extrude: Creates new geometry from selection. Works on vertices, edges, and faces. Note that new geometry is created immediately upon activating this command. Canceling the command will leave behind troublesome duplicate geometry. You must undo the action to prevent the creation of duplicate geometry.

Inset Faces: Creates new faces parallel to each edge in the face selection.

Bevel: Splits selected edges into faces. You can scroll the mouse wheel to increase or decrease the number of faces. By default, adding additional faces will make the edges more rounded. You can also bevel a vertex by using the V key

Duplicate: Creates a copy of the selection. Works for Vertices, Edges, and Faces. Using this command in Object Mode will duplicate the selected object(s).

Bridge Edge Loops: Automatically fills faces between selected edge loops, while eliminating any troublesome interior faces. For best results, both edge loops should have the same number of edges.

Knife: Cuts new edges into a face. You can snap to the midpoint of an edge by holding shift. Toggling C will allow you to project the cut through the entire mesh based on your viewing angle.

Join Vertices: Connects selected vertices with edges along the shortest path by cutting across edges and faces. Using this command in Object mode with two or more mesh objects selected will merge the geometry into a single, discontinuous mesh.

Fill: Connects the selection with new geometry. Works for Vertices and Edges. Note that unlike Join, Fill does not cut across existing edges and faces, which can lead to troublesome overlapping geometry. Fill should only be used to fill across empty space.

Rip Region: Separates all merged contiguous vertices in the selection. Note that vertices are separated immediately upon activating this command. Canceling the command will leave behind troublesome duplicate, non-contiguous geometry. You must undo the action to cancel the vertex separation.
