What are the three most important considerations when dimensioning a multiview drawing according to prevailing best practices?
with dimensions, multiview drawings serve as the main form of communication between designers and manufacturers. All three-dimensional objects have width, height, and depth. Width is associated with an object’s side- to-side dimension.
What are 3 line types used in a multiview drawing?
Orthographic projection involves the use of three planes, which are horizontal, frontal, and profile.
What is the basic for two important multiview drawing standards?
In multiview drawings, generally three views of an object are drawn, and the features and dimensions in each view accurately represent those of the object. The front view of an object shows the width and height dimensions. The views in Figures 8.7 and 8.8 are front views.
What are the views most commonly used in a multiview drawing?
the three most commonly used views in multiview drawing: top, front, and right-side.
When different line types overlap on a multiview drawing what lines are given top priority?
Wha is the correct conventional practice when two or more lines overlap in a multiview drawing? Hidden lines take precedence over visible lines.
How do you determine how many views of an object are necessary in a multiview drawing?
How do you determine how many views of an object are necessary in a multiview drawing? Answer: The number of views needed depends on the complexity of the object. Use only enough views to completely describe the object. 16.
What do hidden lines represent on Multiview drawings?
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.
What is the importance of learning multi view drawing?
The purpose of a Multiview Drawing is to represent a three dimensional object on a two dimensional sheet of paper or in a two dimensional drawing space.
What are the requirements for sketching in Multiview?
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. All three-dimensional objects have width, height, and depth. Width is associated with an object’s side-to-side dimension.
What are the four types of lines used in Multiview drawings?
Straight. Slanted. Curved. Horizontal.
Which view should be drawn first when creating a multiview drawing?
When choosing the front, or principal, view of an object, select the view you would choose if you could only show the viewer one view to describe the object. In creating the multi-view drawing of the bus, the front, or principal, view was drawn first.
What drawing method would be best to use for faithfully enlarging an image when no electronic method is possible?
Enlarging Drawings with Opaque Projectors. Probably the quickest and cleanest enlargement and transfer method available to artists. An opaque projector will project an image of your drawing onto a larger surface allowing you to trace the illuminated image onto your canvas.
When drawing multiple views should the distance between views be the same?
Generally, the distance from the views to the vertical margins and the distance between views (X) will be approximately equal. To locate the views vertically on the paper, lay off the depth of the object (D) on the vertical margin. Divide the remaining distance (E) into two equal parts (E/2).
How many projections should you sketch for any given object?
When making a multiview drawing of an object, you need to draw how many views? Only as many views as are needed to describe the shape. IN MOST CASES, you can completely describe the shape and size of an object by drawing how many views? Two or three views.
Which type of line has precedence over all types of lines?
Precedence of Lines A solid line (object or continuous) takes precedence over a hidden line, and a hidden line takes precedence over a centerline.
What are Multiview drawings?
Multiview Drawing. A multiview drawing is one that shows two or more 2D views of a 3D object.
When determining which line should be displayed when lines overlap on a drawing visible lines take priority over hidden lines?
Dimension lines and extension lines are drawn to the same line weight. ____ 15. When determining which line should be displayed when lines overlap on a drawing, object lines take priority over hidden lines.
Which drawing shows more than one view of an object?
Orthographic drawings are related to isometric drawings. Isometrics show multiple sides of an object at the same time. Orthographics show individual views of the objects.
Which projection has only one view?
Explanation: Orthographic projection is the representation of two or more views on the mutual perpendicular projection planes. But for oblique projection, the object is viewed in only one view.
When projecting views of an object What is the key view?
o 3 view drawings are the most common with the top, front and right side views of an object. The front view is usually the “key view” and gives the most information about its shape. Draw the object so that it will seem balanced. Choose views to show the most visible lines and avoid excessive use of “hidden” lines.
Why would building professionals such as machinists and contractors prefer Multiview drawings over pictorial drawings?
5. 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.
Is to define the distance between extension lines on a drawing?
Normally, these objects are located by dimensioning to the center. The centerline is also used to indicate a finished floor line. Center lines are composed of alternating long and short dashes. The purpose is to define the distance between the two points (extension lines) on the drawing.
Why hidden lines and center lines are used?
Hidden lines in a drawing represent the edges where surfaces meet but are not directly visible. Hidden lines are omitted from pictorial drawings unless they are needed to make the drawing clear.
What are the advantages and disadvantages to using a multiview drawing to represent a design?
Multiview Orthographic Used for: engineering drawings of machines, machine parts. working architectural drawings. Pros: accurate measurement possible. all views are at same scale. Cons: does not provide “realistic” view or sense of 3D form. Usually need multiple views to get feeling for object.
What is the importance of 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 line type is used to indicate the outside edges on a multiview drawing?
You have learned that when making a multiview sketch, hidden edges and surfaces are usually shown with hidden (dash) lines.
