The placement of dimensions is important for the fact that legibility is important when placing dimensions for your sketches.Designers need to fully dimension a part to provide the width, height, and depth so the person that is manufacturing the sketch doesn’t dimension it wrong.

Why is it important to use a set of guidelines to dimension a drawing?
Dimensioning. The purpose of dimensioning is to provide a clear and complete description of an object. A complete set of dimensions will permit only one interpretation needed to construct the part. Dimensioning should follow these guidelines.
What does over dimensioned mean?
What does it mean when a sketch is over dimensioned? A sketch is over dimensioned when. the same measurement/dimension is on 2 or more of the views: such as the over all width is. placed in both the front and top views.
What type of pictorial is used below to represent the puzzle cube piece How can you tell?
In your notebook, create a fully dimensioned multi-view drawing for the following puzzle cube piece. Assume that the puzzle cube piece is made up of six 3/4 in. cubes. What type of pictorial is used above to represent the puzzle cube piece?
Why are dimensions important in a simple illustration?
If a drawing is to be complete, so that the object represented by the drawing can be made as intended by the designer, it must tell two complete stories. It tells this with views, which describe the shape of the object, and with dimensions and notes, which gives sizes and other information needed to make the object.
Why is it important to recognize and understand the alphabet of lines?
Why is it important to recognize the alphabet of lines? The lines in the Alphabet of Lines are used to describe shape, size, hidden surfaces, interior detail, and alternate positions of parts. Each conveys a particular meaning on the drawing.
What does it mean by over dimensioning a sketch?
3. What does it mean when a sketch is over dimensioned? When a sketch is over dimensioned, it just simply has repeated dimensions on the sketch.
What is the difference between size dimensions and location dimensions?
Size dimensions describe the size of each geometric feature.Location dimensions tell the viewer where edges occur inside an object view.
What are the most important guidelines for dimensioning?
Dimensions should be placed in such a way as to enhance the communication of your design.
- Dimensions should be grouped whenever possible.
- Dimensions should be placed between views, unless clearness is promoted by placing some outside.
- Dimensions should be attached to the view where the shape is shown best.
What are dimension guidelines?
Include overall dimensions in the three principle directions – length, width, and height. a. Overall dimensions should be placed the greatest distance away from the object so that intermediate dimensions can nest closer to the object to avoid crossing extension lines.
What are the rules that must be followed while dimensioning?
1. Each dimension should be given clearly so it can be interpreted in only one way. 2. Dimensions should not be duplicated or the same information given in two different ways (dual dimensioning excluded).
What type of pictorial is shown in the first representation in Step 2 How can you tell?
What type of pictorial is shown in the first representation in item 2? How can you tell? It is an oblique pictorial. Because the item is 3D, we know that it is oblique.
What type of note uses a leader line?
Leaders are more thin lines used to point to an area of a drawing requiring a note for explanation. They are preferably drawn at a 45° angles. A cutting plane line (very heavy) helps to show the internal shape at a part or assembly by slicing through the object.
How are angled surfaces dimensioned?
Angled surface may be dimensioned using coordinate method to specify the two location distances of the angle. Angled surfaces may also be dimensioned using the angular method by specifying one location for distance and the angle. Arcs and circles are dimensioned in views that show the arc or circle.
What is the role of dimensioning in assembly drawing?
Dimensions to indicate range of motion or overall size of assembly for reference purposes.
What is the overall dimension?
overall, overall dimension
A total outer dimension of a building material, including any projection, such as a tongue.
Which are the two system of placing dimensions?
aligned system and unidirectional system
Explanation: The two systems of placing dimensions are aligned system and unidirectional system. In the aligned system, the dimension is placed perpendicular to the dimension line.
What do you think the importance of lines and curves in engineering drawing?
It is usually only the very simple type of engineering detail that has an outline composed entirely of straight lines The inclusion of curves within the outline of a component may be for several reasons: to eliminate sharp edges, thereby making it safer to handle; to eliminate a stress centre, thereby making it
What is section line in drawing?
Section lines are special lines placed on a drawing which indicate the area of the drawing through which an imaginary cut has been made to reveal internal details. These lines are drawn at full density and should be drawn at certain dimensions.
Why do engineers use orthographic drawings?
An orthographic drawing is a clear, detailed way to represent the image of an object. It may be used by engineers, designers, architects, and technical artists to help a manufacturer understand the specifics of a product that needs to be created.
What is the meaning of location dimension?
[lō′kā·shən də′men·chən] (design engineering) A dimension which specifies the position or distance relationship of one feature of an object with respect to another.
