Hidden Line In Engineering Drawing

Hidden Line In Engineering Drawing - Web hidden lines (figure 4) are used to show edges and surfaces that are not visible in a view. Web hidden lines (thin) type lines consist of thin short dashes, closely and evenly spaced. They represent dashed lines, which are useful for. In the example above, a visible edge and hidden edge both. < back page 15 of 40 next > this chapter is from the book. Centerlines are one of the most frequently used tools in engineering drawing. They convey critical information, dimensions, and details that guide the construction of complex structures, machinery, and systems. They are drawn as short dashes that are equally spaced. Common examples of such features include bolt holes, pins, discs, etc. They represent dashed lines, which are useful for various purposes.

Web thick or thin dashed line. They are 0.6 mm thick. To prevent confusion in the interpretation of hidden edge lines, you must apply certain standard techniques in drawing these lines. Types of lines include the following: Web hidden detail & lines in engineering drawing & cad. A surface or edge that is shown in one view with an object line will be shown in another view with a hidden line. They are drawn as short dashes that are equally spaced. Sometimes they are used to make a drawing easier to understand. Hidden lines in a drawing represent the edges where surfaces meet but are not directly visible. Web standard engineering drawing line types.

Their basic purpose is to show circular/cylindrical features in a drawing, which are found in abundance in mechanical parts. They convey critical information, dimensions, and details that guide the construction of complex structures, machinery, and systems. Centerlines are one of the most frequently used tools in engineering drawing. Web a hidden line, also known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen. Web lines in engineering drawing are more than just strokes on paper; A variety of line styles graphically represent physical objects. Web hidden detail & lines in engineering drawing & cad. The purpose is to convey all the information necessary for manufacturing a product or a part. Sectioning is used frequently on a wide variety of industrial drawings. A surface or edge that is shown in one view with an object line will be shown in another view with a hidden line.

Types Of Lines Include The Following:

To prevent confusion in the interpretation of hidden edge lines, you must apply certain standard techniques in drawing these lines. Web the sectional view is applicable to objects like engine blocks, where the interior details are intricate and would be very difficult to understand through the use of “hidden” lines (hidden lines are, by convention, dotted) on an orthographic or isometric drawing. It is more than simply a drawing, it is a graphical language that communicates ideas and information. 28k views 9 years ago.

In This Example, Blocks A And B Result After The Block In Figure 1 Has Been “Sectioned”.

Web standard engineering drawing line types. Web thick or thin dashed line. Why not just use a 3d model? These features are typically inside the object or obscured by other surfaces.

In This Comprehensive Guide, We’ll Delve Into The Diverse World Of Lines Used In Engineering Drawings.

Recognizing such dashed lines while parsing drawings is reasonably straightforward if they are outlined with a ruler and compass but becomes challenging when they are hand. Sectioning is used frequently on a wide variety of industrial drawings. Sometimes they are used to make a drawing easier to understand. Web hidden lines are used in engineering drawings to represent features that cannot be seen in a particular view but are necessary to fully define the part or assembly.

These Lines Are Drawn As Thin, Evenly Spaced Dashes.

Modern graphics communication, 5th edition. As the name suggest, they are visible in an engineering drawing. The length of the hidden line dashes may vary slightly as the size of the drawing changes. Web a hidden line, also known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen.
