Basic BinEdit (The Face Menu) Click the menu bar to goto a page about each section.
Add - Create a new face on your model. You are prompted to enter vertex and face type information. You will use this a lot.
Delete current - Erase the current face (the active purple one). Flip face - Switch the current face so that it faces (points in) the opposite direction. Flip Texture X - Mirror the texture from left to right (can be stubborn and uncooperative). Flip Texture Y - Turn the texture upside down. Rotate Texture - Turn the texture 90 degrees. Select all Faces - Select all faces (they will appear green). Deselect All Faces - Unselect the faces (none will be green). Select By Facing - Instead of cycling through the faces and selecting them one by one, this allows you to select all faces pointing in the direction you specify. You will be prompted for information.
Properties - Displays information on the selected (purple) face. Very helpful.
Jump to Face # - Instead of cycling through faces one by one, you can leap ahead to one you choose. You are prompted for the face number. This can be difficult at times because face numbers are not as clearly displayed as vertex numbers. Still, it puts you closer.
