Extension Line In Engineering Drawing

Extension Line In Engineering Drawing - Phantom lines are used to represent a movable feature in its different positions. It is used to point to the beginning or end of an object, feature, or centerline. Drafters and designers attempt to. These lines are drawn as thin, unbroken lines and should not touch the object being dimensioned. Dimension lines show the length of the measured element. Leaders are drawn as straight lines, but they must be drawn at an angle other than horizontal or vertical. In engineering drawings, lines of different types and widths are used to convey important information about the object being depicted. Sometimes, i see dimension lines drawn like this: These thin, unbroken lines are started about one sixteenth of an inch from the outline of the object and extend about one eighth of an inch beyond the outermost dimension line. Extension lines are drawn close to, but never touching, the edges or surface they limit.

An engineering drawing is a subcategory of technical drawings. Dimension lines show the length of the measured element. Web dimension, extension, and leader lines. These thin, unbroken lines are started about one sixteenth of an inch from the outline of the object and extend about one eighth of an inch beyond the outermost dimension line. In engineering drawings, lines of different types and widths are used to convey important information about the object being depicted. Sometimes, i see dimension lines drawn like this: This type is also used to draw outlines of adjacent and revolved sections. Its purpose is to indicate the precise points on the object being dimensioned to which the. Width and types of lines. These lines act as a language that engineers and designers understand to visualize and convey complex ideas accurately.

Extension lines extend toward the element that is dimensioned. Web extension lines help define the specific area or section to which the dimension applies, ensuring clarity and eliminating ambiguity. This is also how my textbook, technical drawing with engineering graphics, 15th edition, has it, and this is what we were taught to do in class. Web 18.06.2020 by andreas velling. Web there are 12 types of lines usually used in engineering drawing. The purpose is to convey all the information necessary for manufacturing a product or a part. You should not dimension to hidden lines: An engineering drawing is a subcategory of technical drawings. Extension lines are drawn close to, but never touching, the edges or surface they limit. You have heard the saying, “a picture is worth a thousand words”.

Extension Lines Cross Object Lines, Center Lines, And Hidden Lines.

Engineering drawings use standardised language and symbols. They extend from the object line and terminate in a break or arrowhead, and are used to. Web dimension and extension lines (figure 6) are thin, solid lines that show the direction, length, and limits of the dimensions of a part. The purpose is to convey all the information necessary for manufacturing a product or a part.

These Thin, Unbroken Lines Are Started About One Sixteenth Of An Inch From The Outline Of The Object And Extend About One Eighth Of An Inch Beyond The Outermost Dimension Line.

To avoid confusion, however, they do not cross dimension lines. Its purpose is to indicate the precise points on the object being dimensioned to which the. They show the exact location of the dimension. You should not dimension to hidden lines:

A Leader Is A Thin Line Used To Connect A Dimension With A Particular Area (Figure 24).

Leaders are used to indicate information about hole diameters, radii, and other information that occurs as a specific location or on a particular surface on the drawing. Usually, the dimension line meets the extension line at right angles. Dimension lines show the length of the measured element. Extension lines extend toward the element that is dimensioned.

Extension Lines Are Drawn Close To, But Never Touching, The Edges Or Surface They Limit.

They are dark and thick lines of any engineering design drawing. These lines act as a language that engineers and designers understand to visualize and convey complex ideas accurately. Sometimes, i see dimension lines drawn like this: Web the extension lines for dimensioning should run from the outlines without leaving a gap and extend beyond the dimension lines.
