What are the types of auxiliary drawing?
There are three basic type of auxiliary views. In the first type, the auxiliary view is projected from the front view of a three view (orthographic) drawing. In the second and third types of drawings, the auxiliary views are projected from the top and side views.
What is auxiliary drawing?
While drawing orthographic projection, such lines of the object which are parallel to principal or vertical plane are represented better. The drawing made on this plane is called Auxiliary View. The size and shape of this drawing are actual ones. The auxiliary plane is assumed to be parallel to the inclined surface.
What is the purpose of auxiliary drawing?
Auxiliary views are a type of orthographic projection used to determine the true size and shape of inclined and oblique surfaces of objects. Normally, auxiliary views are projected from existing principal views. However, auxiliary views can also be drawn first and then used to create a principal view.
How many types of auxiliary planes are there?
3. Auxiliary planes are of _______ types. Explanation: These are A.V.P (Auxiliary vertical plane) and A.I.P. (Auxiliary inclined plane). Auxiliary vertical plane is perpendicular to the H.P. and inclined to the V.P. projection on an A.V.P. is called auxiliary front plane.
What are Multiview drawings?
Multiview Drawing. A multiview drawing is one that shows two or more 2D views of a 3D object.
Why do we need to study auxiliary view in drawing?
Additional or auxiliary views are necessary to represent the true size and shape of other plane surfaces. A plane perpendicular to only one of the three principal planes is said to be in an inclined position; a plane not perpendicular to any of the principal planes is said to be in an oblique position.
What is full auxiliary view?
An auxiliary view is an orthographic view taken in such a manner that the lines of sight are not parallel to the principal projection planes (frontal, horizontal, or profile). There are an infinite number of possible auxiliary views of any given object.
How are auxiliary planes classified?
If the auxiliary plane selected is perpendicular to HP and inclined to If the auxiliary plane selected is perpendicular to HP and inclined to VP, the views of the object projected on the auxiliary plane is called auxiliary front view and the auxiliary plane is called auxiliary vertical plane and denoted as AVP.
Which is fixed VP or HP?
Horizontal Plane
HP: The plane which is Horizontal and perpendicular to VP is Horizontal Plane. Top View (TV): The projection on the HP is called the Top View (TV) or Horizontal Projection or Plan.
