Extension Line In Engineering Drawing

Extension Line In Engineering Drawing - A leader is a thin line used to connect a dimension with a particular area (figure 24). Object lines stand out on the drawing and clearly define the outline and features of the object. Web the graphic feature represents a dimensional entity in a view or image of a drawing. For instance, the 4 surfaces in the figure below. Extension lines have sizing standards too just like dimension lines. Sometimes, extension lines are used to demonstrate the extension of a surface to a theoretical intersection. Extension lines provide a means of displaying a measurement without placing the dimension on the part. They do not touch the object lines and extend slightly past the dimension line.

Web The Extension Lines For Dimensioning Should Run From The Outlines Without Leaving A Gap And Extend Beyond The Dimension Lines.

Extension lines have sizing standards too just like dimension lines. Type c limits or boundaries of partial or interrupted views Web extension lines thin lines used to establish the extent of a dimension. Web an extension line extends a line on the object to the dimension line.

Usually, The Dimension Line Meets The Extension Line At Right Angles.

You can set individual extension lines to display as centerline style. Web line conventions by manufacturinget.org · july 28, 2011 line types (see also asme y14.2m) when you are preparing drawings, you will use different types of lines to convey information. This type is also used to draw outlines of adjacent and revolved sections. Web extension lines on a drawing are fine, dark, solid lines that extend outward from a point on a drawing to which a dimension refers.

The Extension Line Connects The Object Feature With The Dimension Line.

These lines are drawn as thin, unbroken lines and should not touch the object being dimensioned. Line characteristics, such as widths, breaks in the line, and zigzags, all have definite meanings. Extension lines begin 1.5 mm from the object and extend 3 mm from the last dimension line.

There Are Arrowheads At Both End That Terminate At The Extension Lines.

It may be a line, arc, circle, fillet, etc. Extension lines which are added using thin lines determine the extent of a dimension. Can also be used to show extension of a surface to a theoretical intersection as shown in (b). (b) dimension lines show the direction and extent of dimension.
