What is the 6 types of auxiliary views?
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 are the three classifications of auxiliary views?
AUXILIARY VIEW CLASSIFICATIONS – A primary auxiliary view is a single view projected from one of the six principal views. – A secondary auxiliary view is a single view projected from a primary auxiliary view. – A tertiary auxiliary view is a single view projected from a secondary or another tertiary auxiliary view.
What does descriptive geometry involve?
Descriptive geometry is the branch of geometry which allows the representation of three-dimensional objects in two dimensions by using a specific set of procedures. All geometric aspects of the imaginary object are accounted for in true size/to-scale and shape, and can be imaged as seen from any position in space.
What are the types of auxiliary views?
7 Auxiliary Views
- FRONT VIEW AUXILIARIES.
- TOP VIEW AUXILIARIES.
- SIDE VIEW AUXILIARIES.
- SKETCHING AUXILIARY VIEWS.
What is a depth auxiliary view?
Depth auxiliary – The inclined surface will appear foreshortened in a top view and a right-side view. The inclined surface will appear as a line or edge in the top view (see Figure 2). Width auxiliary – The inclined surface will appear foreshortened in a top view and a front view.
What is 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 a height auxiliary view?
Height auxiliary – The inclined surface will appear foreshortened in a front view and a right-side view. The inclined surface will appear as a line or edge in the top view (see Figure 2). Width auxiliary – The inclined surface will appear foreshortened in a top view and a front view.
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.
Who created descriptive geometry?
Gaspard Monge
Gaspard Monge, count de Péluse, (born May 10, 1746, Beaune, France—died July 28, 1818, Paris), French mathematician who invented descriptive geometry, the study of the mathematical principles of representing three-dimensional objects in a two-dimensional plane; no longer an active discipline in mathematics, the subject …
What are views in geometry?
2.1 VIEWS. A view is a two dimensional picture of geometric objects. Not any old picture, but, more precisely, a ‘projection’ of geometrical objects onto a planar surface.
What is the importance of auxiliary view in drawing?
What is the true point of auxiliary view?
Generally, auxiliary views are used to show the true shape or true angle of features that appear distorted in the regular views. The basic steps to find various information only involves the following three steps. They can be repeatedly used as many times depending on the information.
Which is an example of an auxiliary view?
Auxiliary views are named for the principal dimension shown in the auxiliary view. For instance, the auxiliary views in figure below are depth auxiliary views since they show the object’s depth. Any auxiliary view projected from the front view, also known as a front adjacent view, is a depth auxiliary view. 8-5 Depth Auxiliary Views
When do you use an auxiliary view in Photoshop?
Generally, auxiliary views are used to show the true shape or true angle of features that appear distorted in the regular views. Auxiliary views are often used to produce views that show the following: True length of line (TL) Point view of line (PV)
How is descriptive geometry used in engineering design?
Descriptive geometryis one method a designer uses to solve problems. It is a graphic process for solving three-dimensional prob-lems in engineering and engineering design. In the eighteenth century, a French Math-ematician, Gaspard Monge, developed a system of descriptive geometry called the Mongean method. Its purpose was to solve spa-
How are the principal views chosen in drafting?
In choosing the principal views, the drafter positions the object with reference to H and V so as to have the maximum number of its surfaces parallel to H or V or R, a third plane perpendicular to both H and V. Orthographic projection yields the true size and shape of every such surface in the front, the top, or the side view.
