Drawing of Orthographic Projection.įor drawing Orthographic Projection, different planes are placed in a particular order. Read Also: Perspective Projection, Drawing – Its Types, Objectives, Methods. The breadth and height of the object are shown in it.
This view is prepared by looking to the object from the right side or left side. The length and breadth of the object are shown in it. This view is prepared by looking to the object from the upper side. The length and height of an object are shown in this view. This view is prepared by placing the object in front. Generally, the Following Three views are prepared in the orthographic drawing. Views of Orthographic Projection.įollowing views are formed of an object in Orthographic Projection. In the Third Angle System, the top view is upward while the front view is downward and the side view is towards, aside from the front view. In the First Angle System, the top view is placed below while the front view is upward and the side view is by the side of the front view. If the third quadrant is used, then this system is called the Third Angle System. If the first Quadrant is used to draw the projections, then this system is called First Angle System. If these are placed in such a way that they form eight quadrants, then this figure is called Trihedral angle. If these are placed in such a way that they form four Quadrants, then this figure is called Dihedral angle. These are used to draw inclined surfaces of an object. These include the Frontal Plane, Profile Plane, and Horizontal Plane: In addition to this, if a plane is placed at any other place, then it is called Auxiliary Plane. The plane, horizontal or vertical, which are kept perpendicular to each other are called Principal Planes. If the plane is kept in a horizontal position, then it is called the horizontal plane. If the plane is kept in a vertical position, then it is called the vertical plane. These are Top View, Front View, and Side View. Generally, three views of an object are prepared. This plane is faced toward the object whose view is to be prepared. The shape of an object is seen in actual size in such drawing.Ī plane is an imaginary surface on which pictures are prepared imaginably. In this drawing, it is assumed that the object is at infinity.
