AXONOMETRIC- Uses three axes at angles to show three sides of an object.
ISOMETRIC- An axonometric where all axes are projected equally (120 degrees apart).
DIMETRIC- An axonometric where two of the axis angles are symetric (equal).
TRIMETRIC- An axonometric where none of the axis angles are aqual.
OBLIQUE- AN axonometric where two of the axes form a right angle. The front side is seen as is, with no distortion. This is a type of trimetric.
CAVALIER OBLIQUE- Lines going towards rear of object are actual length.
NORMAL or GENERAL OBLIQUE- Lines going towards rear of object are drawn 3/4 of actual length.
CABINET OBLIQUE- Lines going towards rear of object are drawn 1/2 of actual length.
PERSPECTIVE- In an simple axonometric drawing, parallel lines of the real object are depicted as parallel lines on the drawing. In a perpective drawing, parallel lines of the real object are depicted as lines converging to a vanishing point in the background of the drawing. There are many different variations of perspective projections.
These are the my condensed versions from reading drawing texts.
