What do you call a projection plane which is located at the top view of the object is constructed on this plane?
The frontal plane of projection is the plane onto which the front view of a multiview drawing is projected. The top view of an object shows the width and depth dimensions. The top view is projected onto the horizontal plane of projection, which is plane suspended above and parallel to the top of the object.
What are the 3 regular views of an object?
An orthographic projection normally contains three views of the object: the front view in the lower left corner, the top view in the upper left corner, and the right side view in the lower right corner.
What type of line is placed on a view to show the location of the section view?
Section lines are used to show the cut surfaces of an object in section views. They are fine, dark lines.
In which projection only one view showing all the three dimensions of an object is drawn on a plane of projection?
Explanation: Oblique projection is one method of pictorial projection. Oblique projection shows three dimensional objects on the projection plane in one view only.
What is isometric and orthographic projection?
Isometric, or pictorial drawings, which represent an object in a three dimensional fashion by showing 3 surfaces of the object in one drawing. Orthographic, or plan view drawings, which represent an object in a two dimensional fashion by showing each surface of the object in its actual shape.
What do you call a view that is drawn above the front view?
Elevation is the view of a 3-dimensional object from the position of a vertical plane beside an object. In other words, an elevation is a side view as viewed from the front, back, left or right (and referred to as a front elevation, [left/ right] side elevation, and a rear elevation).
What is a sectional view?
A sectional view or a section looks inside an object. Sections are used to clarify the interior construction of a part that cannot be clearly described by hidden lines in exterior views. By taking an imaginary cut through the object and removing a portion, the inside features may be seen more clearly.
What is a multi view?
A multiview drawing is one that shows two or more two-dimensional views of a three-dimensional object. Multiview drawings provide the shape description of an object. When combined with dimensions, multiview drawings serve as the main form of communication between designers and manufacturers.
What are the different views of an object?
Front, top, right side, left side, rear, and bottom. Although six different sides can be drawn, usually three views of a drawing give enough information to make a three-dimensional object. These views are known as front view, top view and end view. Other names for these views include plan, elevation and section.
What are the types of lines?
They are: Horizontal Lines. Vertical Lines. Parallel Lines. Perpendicular Lines.
What is sectional top view?
The view obtained by cutting an object with an imaginary cutting plane is called Sectional View. The surface produced by cutting the object by the section plane is called Section. It is indicated by thin section lines uniforemly spaced, generally at an angle of 45′.
What is line projection?
Projection lines. Projection lines. Projection lines are extensions of lines that assist in 2D drawing. You can use projection lines to help you create new geometry, and any constraints you create with them remain active even after you turn projection lines off.
What is another name for isometric drawing?
isometric drawing, also called isometric projection, method of graphic representation of three-dimensional objects, used by engineers, technical illustrators, and, occasionally, architects.
What are the types of projection in engineering drawing?
There are four main types of projection methods used in mechanical drawing in order to convey information such as geometry, dimensions, tolerances, material and finish.Let our resources save you time and money! Orthographic Projection. Axonometric Projection. Oblique Projection. Perspective Projection.
How many types of projection are Mcq?
Online Test 12. The types of projection are a. Parallel projection and perspective projection b. Perpendicular and perspective projection c. Parallel projection and Perpendicular projection d. None of these.
What is isometric angle?
Isometric drawing is a form of 3D drawing, which is set out using 30-degree angles. It is a type of axonometric drawing so the same scale is used for every axis, resulting in a non-distorted image.
What is oblique sketching?
The oblique sketching is a pictorial representation of an object, in which the diagram is intended to depict the perspective of objects in three dimensions. This type of drawing can be done either in a normal, cabinet or cavalier style.
What is the meaning of oblique projection?
An oblique projection is a parallel projection in which the lines of sight are not perpendicular to the projection plane. Commonly used oblique projections orient the projection plane to be perpendicular to a coordinate axis, while moving the lines of sight to intersect two additional sides of the object.
What is a front view drawing?
A front view is a projection view obtained by drawing perpendiculars from all points on the edges of the part to the plane of projection. The plane of projection upon which the front view is projected is called the frontal plane.
What are the types of auxiliary view?
7 Auxiliary Views FRONT VIEW AUXILIARIES. TOP VIEW AUXILIARIES. SIDE VIEW AUXILIARIES. SKETCHING AUXILIARY VIEWS.
What is front view and top view?
Front view = Elevation (The views from the front and sides are called the elevations) Top view = Plan (The view from the top is called the plan).
What is cross section view?
The Cross Section View can be useful any time you want to see inside of your model. For example, if there was a hollow cavity, or internal features, or anything that you can’t see from the outside of the part, this view can come in handy. This can also be helpful to spot any mesh errors within your model.
What is a section view on a blueprint?
∎ A section view is a view used on a drawing to. show an area or hidden part of an object by. cutting away or removing some of that object.
What is an aligned section?
An aligned section view / cut is a view created from a cutting profile defined from non parallel planes. In order to include in a section certain angled elements, the cutting plane may be bent so as to pass through those features. The plane and feature are then imagined to be revolved into the original plane.
What is a Dimetric view?
Definition of dimetric projection : an axonometric projection in which only two faces are equally inclined to the plane of projection.
What are the different types of oblique projection?
Oblique Projection There are two types of oblique projections − Cavalier and Cabinet. The Cavalier projection makes 45° angle with the projection plane. The projection of a line perpendicular to the view plane has the same length as the line itself in Cavalier projection.
What is a Miter line?
Use of a Miter Line. A miter line (OE in the figure) offers a convenient method of laying out a third view while you are in the process of drawing two views. Place the miter line (OE) to the right of the top view at a convenient distance, keeping the appearance of a balanced drawing.
