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 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 a Dimension line?
The dimension line is a thin line, broken in the middle to allow the placement of the dimension value, with arrowheads at each end (see diagram below). … An extension line extends a line on the object to the dimension line.
What are dimensioning tools?
The Dimensioning tab contains tools that are useful for creating objects which must fit predefined dimensions or for dimensioning objects you have created. These tools can also be accessed via the Tools > Dimensioning menu. They can be used to dimension a line, edge, bounding box, angle, and radius/diameter.
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.
What is datum dimensioning?
A datum dimension is a group design object. It allows for the dimensioning of a linear distance of a collection of objects, relative to a single reference object. The first object chosen is the ‘base’.
Is it okay to dimension hidden lines?
Dimensioning to hidden lines should be avoided wherever possible. Use auxiliary cross sectional views instead. … Longer dimensions should be placed outside all intermediate dimensions so that dimension lines will not cross extension lines.
What is unidirectional dimensioning?
UNIDIRECTIONAL DIMENSIONS: In the unidirectional dimension system, all dimension figures and notes are lettered horizontally and are read from the bottom of the drawing. The unidirectional dimension system is preferred over the aligned system because it is easier to read and understand.
What is the name of arrangement of dimensioning?
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.
What are the two systems of 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 8 rules of dimensioning?
Terms in this set (8)Rule 1: Dimensions should not be duplicated, nor should the same info be given in two different ways.Rule 2: Dimensions should be attached to the view that best shows the contour of the feature being dimensioned.Rule 3: … Rule 4: … Rule 5: … Rule 6: … Rule 7: … Rule 8:
What are leader lines?
A leader line is a line that establishes a connection between a graphical representation of an item and some text. A leader points to a bit of our drawing and says: ‘Oi – Look Here’ and ‘Read This! ‘.
What are 5 types of lines?
There are 5 main types of lines in art: vertical lines, horizontal lines, diagonal lines, zigzag lines, and curved lines. Other types of lines are simply variations of the five main ones.
What are dimension lines in technical drawing?
The dimension line is a thin line, broken in the middle to allow the placement of the dimension value, with arrowheads at each end (figure 23). Figure 23 – Dimensioned Drawing. An arrowhead is approximately 3 mm long and 1 mm wide. That is, the length is roughly three times the width.
What are the 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.
Which line is used for visible outlines?
Continuous thick Used for visible outlines and edges. Dashed thin line. Used for hidden outlines and edges. Chain thin.
What are the principles of dimensioning?
Three principles of dimensioning must be followed:Do not leave any size, shape, or material in doubt.To avoid confusion and the possibility of error, no dimension should be repeated twice on any sketch or drawing.Dimensions and notations must be placed on the sketch where they can be clearly and easily read.
What is dimensioning in drawing?
Definition Dimensioning is the process of specifying part’ s information by using of lines, number, symbols and notes . … Lines to be used are always thin continuous line. 2. Symbol or abbreviation commonly found in a drawing are – “ diameter ” is represented by a symbol “ ”.
What is the ratio of arrow?
1. Arrow head ratio 1:3 is maintained.
What is projection of a line?
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.
