• ## Why is Modeling Useful?

Modeling has become an essential part of design.  It has been used in a variation of fields from film, games, 3D printing, architecture, jewelry design, and illustration, just to name a few.  It's future in technology is cemented and knowing how to model in 3D can expand your skills as an artist when you are looking for work.
• ## What are Polygons?

"The polygon is the basic building block of all 3D models. Here we discover its properties, like the face normal, which shows the direction the polygon is facing and it's three components the face, edge and vertex. Complicated objects are made of lots of polygons put together." -The Guerrilla CG Project

• ## Vertices, Edges, and Faces

Vertices: In geometry, a vertex (plural: vertices or vertexes) is a point where two or more curveslines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.

Edge: In geometry, an edge is a particular type of line segment joining two vertices in a polygonpolyhedron, or higher-dimensional polytope.

Faces: In solid geometry, a face is a flat (planar) surface that forms part of the boundary of a solid object; a three-dimensional solid bounded exclusively by flat faces is a polyhedron.

• ## Select, Translate, Rotate, and Scale

Below are useful hotkeys to help you select, translate, rotate, and scale a polygon.

Select = Q

Translate = W

Rotate = E

Scale = R
