Leader Line In Engineering Drawing

Leader Line In Engineering Drawing - To ensure clear and consistent communication, drawings must adhere to. Web standard engineering drawing line types. Web extension lines begin 1.5 mm from the object and extend 3 mm from the last dimension line. Basic conventions and applications for leader lines and reference lines — part 23: Leader lines are used to mention a specific note to a feature on a drawing, as well as to direct dimensions, symbols, item numbers, and part numbers. They typically have an arrow or dot at one end and point to the object of interest. Leader lines are used to point to specific features or annotations in a drawing. Web a leader line is a line that establishes a connection between a graphical representation of an item and some text. In mechanical engineering drawings, linear dimensions are classified in size, distances and radii (iso/tr 14638). This type is also used to draw outlines of adjacent and revolved.

In these examples, the leader lines are indicated with a red arrow. Web leader line — a thin, solid line with arrow drawn under an angle & indicating the feature with which a dimension or note is associated. There are several acceptable types of. They are added using thin lines. These lines are solid and has no break in them. You have heard the saying, “a picture is worth a thousand words”. Leader lines are used to mention a specific note to a feature on a drawing, as well as to direct dimensions, symbols, item numbers, and part numbers. To prevent confusion in the interpretation of hidden edge lines, you must apply certain standard techniques in drawing these lines. 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. Leader lines are very useful for placing text or a dimension in a limited space on a drawing and for adding specific notes pertaining to the drawing.

In These Examples, The Leader Lines Are Indicated With A Red Arrow.

Here is the list of cases where the continuous thin line will be used: The leader line can be a straight line or curved. There are several mark types that can be displayed at the end of leader lines. The leader line itself should be a continuous thin line (see this post on linetype definitions ).

Dimensions Make Use Of Dimension Lines, Extension Lines And Leader Lines.

To ensure clear and consistent communication, drawings must adhere to. Leader lines are used to mention a specific note to a feature on a drawing, as well as to direct dimensions, symbols, item numbers, and part numbers. This type is also used to draw outlines of adjacent and revolved. In mechanical engineering drawings, linear dimensions are classified in size, distances and radii (iso/tr 14638).

They are typically utilized when pointing to notes, labels, or callouts that provide additional information about a particular object or detail. They typically originate from a note, label, or callout and connect to the object or area being referenced. A leader may also be used to indicate a note or comment about a specific area. A leader points to a bit of our drawing and says:

Lines On Mechanical Engineering Drawings

A variety of line styles graphically represent physical objects. Web leader lines are used to direct attention to specific areas or features on an engineering drawing. However, extension lines can cross other extension lines or visible lines. Leader lines are straight or curved lines that have an arrow or dot at one end and are used to point to specific features or annotations in a drawing.
