How do you determine the orientation of orthogonal projections in a multi-view drawing? You’d first need to determine what your “front view
” will be by choosing the side with the longest dimension
, the least hidden lines/most amount of visible faces, 2.

Why is orthographic projection referred to as Multiview sketching?
A multiview sketch, also referred to as an orthographic projection sketch, is
the standard sketch format used by engineers to communicate ideas to professionals in the building trades
. … In this activity, you will develop your ability to see and sketch objects as a series of related two-dimensional views.
How would you describe the geometric relationship that exists between the adjacent views of a multiview drawing perpendicular parallel aligned?
2. How would you describe the geometric relationship that exists between the adjacent views of a multi-view drawing? Answer: The geometric relationship between the views would be
that they have the same exact dimensions as the “adjacent” view below it or next to it.
What is multiview drawing or orthographic projection?
In technical drawing and computer graphics, a multiview projection is
a technique of illustration by which a standardized series of orthographic two-dimensional pictures are constructed
to represent the form of a three-dimensional object.
A hidden line, also known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps,
to show edges, surfaces and corners which cannot be seen
. Sometimes they are used to make a drawing easier to understand. Often they are omitted in an isometric view.
Why do professionals prefer Multiview drawings over pictorial?
Why would building professionals, such as machinists and contractors, prefer multiview drawings over pictorial drawings? So
they can look at the front view, sides, and top to know all dimensions of the building without having to estimate
.
Why are three views used to show the object?
Complex designs require a three view orthographic drawing. Show the object as
it would appear to a person looking directly at the object
. They are commonly used to communicate designs to people who do not understand or use orthographic drawings. The most common type of pictorial drawing used.
What are the six principal views of an object?
surfaces of the object positioned so that they are parallel to the sides of the box, six sides of the box become projection planes, showing the six views –
front, top, left, right, bottom and rear
.
What are the three main types of pictorial drawings?
- Isometric.
- Oblique.
- Perspective.
What is the symbol of Third angle projection?
The third angle symbol is shown in Figure 1. It is represented by
the circular top view of the cone with the right view of the cone to the right of it
. In the right-side view, the narrow end of the cone is pointed towards the top view.
Who Uses first angle projection?
First angle projection is widely used
throughout all parts of Europe
and often called European projection. Third angle is the system used in North America and alternatively described as American projection.
What is 1st and 3rd angle projection?
In third-angle projection, the view of a component is drawn next to where the view was taken. In first-angle projection,
the view is drawn on the other end of the component
, at the opposite end from where the view was taken.
Hidden lines are used to
show surfaces that are not directly visible
. All surfaces must be shown in all views. If an edge or surface is blocked from view by another feature, it is drawn using a hidden line. Figures 4-11 and 4-12 show objects that require hidden lines in their orthographic views
Which lines on a drawing should be the thickest?
The
direction of the cutting line
is shown with a line called a cutting plane lineHeavy dashed line that shows a theoretical cut through an object.. This is the thickest line that may appear on a drawing. It is made up of a series of 3/4′′ long (19mm) and double lines 1/8′′ (3.2mm) long that are about 0.040′′ (1mm) thick.
would appear as hidden lines in an orthographic multiview drawing? These are the three views associated with the object you just built. Hidden lines are dashed lines used to represent internal features that are obscured by the object. These hidden lines represent
the obscured corner of the notch
