Isometric drawing means equal measure. 6. Dimetric is like isometric drawing. 7. Trimetric has 3 different leading edges. 8. In isometric drawing, the 3 leading edges are not equal. 9. Cavalier and cabinet is a kind of oblique drawing. 10. One-point perspective has 2 vanishing point. 11. A two-point perspective has 2 vanishing point. 12. A one-point perspective is called angular perspective. 15. A parallel perspective has one vanishing point. 16. A parallel perspective is the same as angular perspective. 17. A one-point perspective is called parallel perspective. 18. A two-point perspective has one vanishing point. 19. An angular perspective is called two-point perspective. 20. An angular perspective has only one vanishing point. 21. The front-view is called the elevation. 22. The front surface of the parallel perspective is at an angle to the plane of projection. 23. The angular perspective has two-vanishing points. 24. The top view is not called the plan. 25. The eye-level is at the level of the eye. 26. The two vanishing point is called center of vision. 27. The left and right vanishing point is used in angular perspective. 28. S.P. means station perspective. 29. The C.V. is used as the vanishing point of the parallel perspective. 30. The ground line is used where the object rests.​
