Navigation
Navigation= x, y, z + shift Used to roam around the blender user perspective.
Move=g Used to move objects around using x, y and z.
Rotate=r Used to rotate an object to different degrees.
Scale=S Used to increase the dimensions of an object (height, width and length
Edit
Edit=Tab Used to grant access to the tool bar.
Extrude= Used to push and pull the faces, edges and vertices of and object.
Loop Cut=ctrl r Used to make cuts in objects to give more dimension.
Inset= I Used to add new faces into existing faces.
Geometry
Polygon= A Square. The more polygons the more complex, some consoles can only withstand a certain amount of them.
Edge= A line. Located on the outside of a shape.
Vert= A dot. Found at the corners of a shape.
Topology
N-gons are shapes with more than 5 sides and are recommend to be avoided when constructing meshes. The reason being is that not only will the attributes be to high in polys but working with them becomes difficult.
Quads are 4 sided shapes and unlike N-gons are easier to manipulate and are better to work with.
Tri’s are 3 sided shapes and like quads are easier to work with.
Surface normal
Vertex normal and polygon normal Surface normal (vertex and polygon) are direction in which the vertex or polygon is facing.
