What are the rules of dimensioning?
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.
A dimension should be attached to only one view (i.e., extension lines should not connect two views)..
What is meant by dimensioning?
Dimensioning is the process of measuring either the area or the volume that an object occupies. It is the method of calculating capacity for the storage, handling, transporting and invoicing of goods.
What is short break line?
Short break lines are thick, wavy solid lines that are drawn freehand. When either of these break lines is used to shorten an object, you can assume that the section removed from the part is identical to the portions shown on either side of the break. (thin and long with a zigzag)
What are the two methods of dimensioning in common use?
Two methods of placing dimensions are currently used: the aligned system and the unidirectional system. In the aligned system of dimensioning, the dimensions are placed in line with the dimension lines. Horizontal dimensions always read from the bottom of the sheet. Vertical dimensions read from the right.
What are the 4 basic components of an engineering drawing?
The main purpose of engineering drawings is to communicate to other engineers, machinists, etc….Dimensions have four basic components:Dimension Text.Dimension Line andArrows.Extension Lines.Gap.
What is the difference between aligned and unidirectional dimensioning?
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. In the unidirectional system, all dimensions are placed such that they can be read from the bottom of the drawing sheet.
What are the different types of dimensioning?
The basic types of dimensioning are linear, radial, angular, ordinate, and arc length. Use the DIM command to create dimensions automatically according to the object type that you want to dimension.
What four lines are used to aid in dimensioning?
There are four methods: parallel, running, chain, and combined dimensioning. Some methods of dimensioning a drawing can create an accumulating error.
What is the heaviest line in a drawing?
The heaviest line weight indicates the ground line cut. The next heaviest line weight “profiles the planes closest to the plane of projection” (Ching & Juroszek, 1998, p. 152). Medium line weight indicates distance from picture plane, progressively getting lighter to describe objects further from the picture plane.
Which line 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.
What are the two systems of placing dimensions on a drawing?
There are two basic methods of placing dimensions on a sketch. They may be placed so they read from the bottom of the sketch (unidirectional dimensions) or from the bottom and right side (aligned dimensions). The unidirectional system is usually best, because it is more easily read by workmen.
What is the name of the dimensioning arrangement?
Explanation: In chain dimension, the dimensions are arranged in a straight line. The type of dimensioning in which the dimensions are arranged parallel to each other is called a Parallel Dimension. The combination of both the type is called as a combined dimension.
Which is the best example of dimensioning the cylinder below?

What does it mean when a dimension is called out on a drawing?
Directly toleranced dimensions, use the tolerances called out in the drawing format, or have the tolerance included in the dimension. … They are “exact” dimensions. They are signified by placing a box around them.
