In the example above I’m going to extrude the selected edges 2 meters in X-direction several times. The way to do this is to use short keys to speed up the process. So to do this I start with:

1. E + X + 2
2. SHIFT + R to repeat the first step several times.

We use SHIFT + R in Blender to repeat the last operation.

Also we can extrude edges in other directions, like for example:

1. E + Y + 2 to extrude 2 meters in Y-direction
2. E + Z + 2 to extrude 2 meters in Z-direction.

If we change transformation orientation to NORMAL, we’ll get some changes in the directions, where:

• E + X will now extrude the edge in Y-direction (global)
• E + Y will now extrude the edge in Z-direction (global)
• E + Z will now extrude the edge in X-direction (global).

Usually NORMAL is way better for extruding faces along the NORMAL – which is these small blue lines sticking up from the surface of the mesh, which also tells us if the face is outside/inside depending on the direction of the normal blue line. Blender isn’t showing normals as arrows but as vectors.

We can also select from the menu line Face > Extrude Faces Along Normals – to extrude several selected faces in the direction of the NORMAL. This happens immediately when moving the mouse cursor.
