What is an auxiliary view and why would it be important?
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 the primary auxiliary view?
A primary auxiliary view is projected onto a plane that is perpendicular to one of the principal planes of projection and is inclined to the other two. A secondary auxiliary view is projected from a primary auxiliary view onto a plane that is inclined to all three principal projection planes.
What are the 6 types of auxiliary view?
Auxiliary views are used to find: 1) true length of an inclined or oblique line; 2) true size and shape (TSS) of an inclined or oblique face 3) edge view of oblique face; 4) point view of inclined or oblique line; 5) true size and shape of features on incline or oblique faces.
What is the order of creating an auxiliary view?
To show the true size and shape of surface ABCD an auxiliary view can be created by positioning a line of sight perpendicular to the inclined plane, then constructing the new view.
How are auxiliary planes classified?
If an edge or a face is to be shown in true size, it should be parallel to the plane of projection. These additional planes of projection which are set up to obtain the true sizes are called Auxiliary Planes. ▪ The views projected on these auxiliary planes are called Auxiliary Views.
What is a secondary auxiliary view?
The secondary auxiliary view is a projection from the primary auxiliary view onto a plane perpendicular to the true length edges. In this view, the sides and bottom of the groove appear as edges, as if you are looking into the end of the groove.
What is the difference between primary and secondary auxiliary view?
What do you call an auxiliary view that has been projected from a primary auxiliary view?
STUDY. secondary auxiliary view. A view projected from a primary auxiliary view is called a. front auxiliary view.
What are the minimum views required to create an auxiliary view?
A minimum of two orthographic views is necessary. The space between these views is generally greater than normal. The second step is to decide which line or surface is to be shown in an auxiliary view andwhich orthographic view it will be projected from.
What is the view developed from another auxiliary view called?
When an object is revolved to develop a view of an oblique surface, the resulting drawing is called a rotation. When a cutting plane is not parallel to any of the normal views, the resulting cross sectional view is called an auxiliary section. Hidden lines are never shown in an auxiliary view.
How will a frontal line will appear in an auxiliary view?
For example, if the inclined surface is perpendicular to the frontal plane then such, an auxiliary will be called Frontal Auxiliary View. While drawing, it is attached to the frontal plane. If the inclined surface is perpendicular to the top plane, then such an auxiliary will be called Top Auxiliary Views.
What is the relationship of an auxiliary view to the normal views?
22. SUMMARY 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.
What is auxiliary plan?
The first auxiliary projection in Fig. Note that auxiliary views are drawn on planes other than the principal projection planes. A plan is projected from an elevation and an elevation from a plan. Since this is the first auxiliary view projected, and from a true plan, it is known as a first auxiliary elevation.
How do you read auxiliary views?
AUXILIARY VIEWS ARE When an object has inclined surfaces, these do not show up in true shape or size in regular views. However, a view on a plane parallel to the inclined surface does show its true size and shape. This is an auxiliary view. It, along with the other regular views describe the object better.
What is true shape?
The true length of a line and the true shape of an object are their actual lengths and shapes. Two views are needed to find the true length of a line or shape to overcome errors that could be caused by the viewing angle. …
How do you find true shapes?
To get your plane into true shape, find the edge view, then draw a folding line parallel to edge view and use transfer distances to transfer all of the points of the plane to this final view. This will get you the true shape of the plane.
