Quick Answer: What Is The Dimension Extension Line?

What is the purpose of extension line?

Extension lines continue or extend from the surface of the object and establish the size of the dimension.

They do not touch the object lines and extend slightly past the dimension line.

Extension lines provide a means of displaying a measurement without placing the dimension on the part..

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?

Line Conventions, Continued Extension lines Extension lines are thin lines that extend from the object outline or point on the object to a place outside the image area. Extension lines define areas for dimensions.

What is the difference between a dimension line and an extension line?

Dimension & Extension Lines. Dimension Lines – show the direction and extent of the numerical size. … 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.

Can dimension lines cross?

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

What are the 3 types of drawing dimensions?

The basic types of dimensioning are linear, radial, angular, ordinate, and arc length.

What are the 4 product line expansion?

There are four “stages” of the life cycle of a product: introduction, growth, maturity, and decline. The launch is exciting and is often followed by a surge of sales, but at some point, the product will wear itself out.

What are the types of brand extension?

What is an example of a line extension?

A product line extension is when an existing brand launches new products in a product category they already offer products within. For example, when a soft drink company offers a new flavor of soda.

What is double dimensioning?

4.5/5 (66 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 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 typical dimension line terminators called?

ArrowheadsArrowheads are typical dimension line terminators. There are other acceptable dimension line terminators. Arrowheads point directly to the object that is being dimensioned or the extension lines at the end of the dimension. Arrowheads are made three times as long as they are wide.

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.

Where is the dimension written on a dimension line?

Dimension Lines In machine sketches and drawings, in which fractions and decimals are used for dimensions, the dimension line is usually broken near the middle to provide open space for the dimension numerals.

What are the 8 rules of dimensioning?

What is a line extension strategy?

A product line extension strategy is an approach to developing new products for your existing customers or for prospects who do not currently buy from you. Extending a product line involves adding new features to existing products, rather than developing completely new products.

What line weight should dimension lines be?

0.25mmThe default line weight in both Autocad and Inventor is 0.25mm. The recommended Line weight for the ‘Drawing frame’ (Border) for engineering drawings is 0.7mm.

Which best describes the dimensions of a line?

It extends infinitely in both directions. It has only length therefore, it is one dimensional. Hence, the best describes the dimensions of a line is “A line has one dimension because it is made up of all points that extend infinitely in either direction. ‘

What is another name for an object line?

A visible line, or object line is a thick continuous line, used to outline the visible edges or contours of an object. A hidden line, also known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen.

Can Leader lines cross extension lines?

22. Dimension lines and extension lines should not cross, if avoidable. However, extension lines may cross each other. … Leaders for notes should be straight lines (not curved), drawn at an angle, and aimed towards the center (but stopping at the edge of the circle) in the circular views of holes whenever possible.

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! ‘.
