What are Lines & Types Of Lines in Engineering Drawing ? YouTube

Web leader line — a thin, solid line with arrow drawn under an angle & indicating the feature with which a dimension or note is associated. Web dimension, extension, and leader lines. “drawing” usually means.

These lines act as a language that engineers and designers understand to visualize and convey complex ideas accurately. Dimension, projection, leader, hatching type lines must be drawn thin and continuous. They are dark and thick.

Web engineering drawing is a specialized form of communication that uses a strict set of symbols, standards, and perspectives to depict mechanical, electrical, or structural designs. Web there are 12 types of lines usually used.

The extension lines for dimensioning should run from the outlines without leaving a gap and extend beyond the dimension lines. Leaders are more thin lines used to point to an area of a drawing requiring a note for explanation. Dimension, projection, leader, hatching type lines must be drawn thin and continuous. The leader line should terminate in an arrowhead or dot. These types of lines also known as object lines.

As the name suggest, they are visible in an engineering drawing. Web the purpose of this guide is to give you the basics of engineering sketching and drawing. They are dark and thick lines of any engineering design drawing.

In Engineering Drawings, Lines Of Different Types And Widths Are Used To Convey Important Information About The Object Being Depicted.

A cutting plane line (very heavy) helps to show the internal shape at a part or assembly by slicing through the object. They are 0.6 mm thick. Web dimension, projection, leader, hatching lines. We will treat “sketching” and “drawing” as one.

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.

“drawing” usually means using drawing instruments, from compasses to computers to bring precision to the drawings. Web leader lines are drawn as straight lines (but not horizontal or vertical) that originate from a specific location and end with an arrowhead or a dot. The leader line should terminate in an arrowhead or dot. Web there are 12 types of lines usually used in engineering drawing.

The Orthogonal Projections Are 2D Drawings Of 3D Objects.

You can draw them automatically one at a time, in sets of parallel lines, or freehand, point by point. Thin, broken lines indicating the center of an object or a hole. Thin lines leading from a dimension figure to the related extension line. Dimension, projection, leader, hatching type lines must be drawn thin and continuous.

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.

Web leaders in an engineering drawing are lines that point to a text or other item on the drawing. Leaders are more thin lines used to point to an area of a drawing requiring a note for explanation. Web leader or pointer lines: “sketching” generally means freehand drawing.

Provide knowledge of different geometrical construction methods and their applications. Here is the list of cases where the continuous thin line will be used: Familiarize students with the methods of pictorial and orthographic projection principles and applications. A cutting plane line (very heavy) helps to show the internal shape at a part or assembly by slicing through the object. The leader line itself should be a continuous thin line (see this post on linetype definitions ).
