In todayâ€™s video, learn to use the extrude tool in Blender to create 3D shapes, add recesses and extrusions, and much more!

Extrude tool is a tool used to take an edge, a surface, or a group of surfaces and â€œextrudeâ€ it into 3d
Can extrude both out and in. Out adds geometry, in can add things like recesses
Can also tap the â€œsâ€ key to enter extrude/scale mode. This is especially useful when you need to extrude something outward uniformly on an object.
Now letâ€™s talk a bit about another kind of extrusion â€“ extrude along surface normal. When extruding around objects with a bit of a non-uniform shape, you can use the option for â€œextrude along surface normals.â€ This basically allows you to extrude perpendicular to all selected faces, giving you a uniform recess.
