Extension Line In Engineering Drawing

Extension Line In Engineering Drawing - An extension line is a thin line, Web extension line — a thin, solid line perpendicular to a dimension line, indicating which feature is associated with the dimension. They extend from the object line and terminate in a break or arrowhead, and are used to guide the dimension line. In the 2009 standard, this symbol cannot be applied to a surface in this manner. Web extension lines help define the specific area or section to which the dimension applies, ensuring clarity and eliminating ambiguity. Dimension lines are thin and are used to show the actual size of an object. Sometimes, extension lines are used to demonstrate the extension of a surface to a theoretical intersection. They should not cross dimension lines. Dimension line arrowheads touch extension lines. The first dimension line should be approximately 12 mm (0.6 in) from the object.

Extension Lines Which Are Added Using Thin Lines Determine The Extent Of A Dimension.

For instance, the 4 surfaces in the figure below. Usually, the dimension line meets the extension line at right angles. 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. In the 2009 standard, this symbol cannot be applied to a surface in this manner.

It may be a line, arc, circle, fillet, etc. Extension lines are thin lines that are used to indicate the extent of a feature to which a dimension is attached. Dimension line arrowheads touch extension lines. Extension lines are solid and thin lines like dimension lines.

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

Web extension lines continue or extend from the surface of the object and establish the size of the dimension. Feature’s corners and the end of the extension line. Web the graphic feature represents a dimensional entity in a view or image of a drawing. These lines are drawn as thin, unbroken lines and should not touch the object being dimensioned.

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

Web an extension line extends a line on the object to the dimension line. Web the thin, dark line extending from an object that shows the limits of a dimension line is called an extension line. Web extension line — a thin, solid line perpendicular to a dimension line, indicating which feature is associated with the dimension. 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.
