Quick Answer: What Is The Difference Between Dimension Lines And Extension Lines?

What is an example of a line extension?

What is a brand line extension.

A company introduces a brand line extension by using an established product’s brand name to launch a new, slightly different item in the same product category.

For example, Diet Coke™ is a line extension of the parent brand Coke™..

What is the purpose of leader line and extension line?

Extension lines are also thin lines, showing the limits of dimensions. Dimension line arrowheads touch extension lines. 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.

What are extension lines Leader lines and dimension lines?

(a) Extension lines are used to indicate the extension of an edge or point to a location outside the part outline. (b) Dimension lines show the direction and extent of dimension. (c) Leader lines are used to direct an expression, in note form, to the intended place on the drawing.

What are dimension and extension lines?

Extension lines indicate the points between which the dimension figures apply. They are drawn perpendicular to the dimension lines, start with a visible gap (~1/32″) between them and the object, and terminate 1/8″ (3.2 mm) beyond the last arrowhead.

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 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 are dimensioning tools?

The Dimension tool allows you to measure and show the distance between two points in your layout. It also allows you to set a certain distance between objects, or to change an object’s size. The tool is available in the 2D Plan and 2D Elevation views.

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:

Can extension lines cross object lines?

Dimension lines and extension lines should not cross, if avoidable. However, extension lines may cross each other. 23. When extension lines cross other extension lines or visible object lines, no break in either line should be made.

What are alphabet lines?

The Alphabet of Lines is a list of line symbols that engineers use in technical drawings to communicate specific shapes, sizes or surfaces. In the Alphabet of Lines, thick, dark lines represent the outline of an object, showing its visible surfaces and edges.

What is a extension line?

Extension Lines – are used to extend a surface or a point beyond the outline of the object so that a numerical size can be related to that surface. A small gap is left between the extension line and the outline to which it refers.

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 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. 9. A dimension should be attached to only one view (i.e., extension lines should not connect two views).

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 relationship does the Dimension line have with its extension line?

Usually, the dimension line meets the extension line at right angles. There should be a gap of about 1 / 16″ where the extension line would meet the outline of the object, and the extension line should go beyond the outermost arrowhead approximately 1 /8″.

What is double dimensioning?

4.5/5 (89 Views . 14 Votes) Dual dimensioning is the drafting practice of using multiple units of measure in a dimension in the same direction of a feature. SolidWorks and many other CAD programs support dual dimensioning.

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.
