Hidden Lines Engineering Drawing

Hidden Lines Engineering Drawing - Web visible lines are used to represent features that can be seen in the current view. This animated video details and showcases their use, purpose and advantages &. 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. We will treat “sketching” and “drawing” as one. The arrows in show the direction of view. As the name suggest, they are visible in an engineering drawing. Hidden lines are used to represent features or edges that are not visible from a particular viewpoint. To show internal features with more clarity than regular projections or hidden lines,it also helps reducing number of hidden lines.in assembly drawings, hardware components (e.g. Web a broken out section is easy to do on a drafting board, and hard to do in 3d cad like solidworks. Web i have heard two schools of thought concerning hidden lines:

Hidden Lines Show Edges And Contours Of Important Features That Are Obscured By The Geometry Of The Part.

Nuts, screws, washers) are typically not sectioned. Hidden lines in a drawing represent the edges where surfaces meet but are not directly visible. Web in an engineering drawing, visible lines are the thick, solid lines that represent the visible edges and boundaries of an object or part. For example, the length of an internal step of a part may be shown using hidden lines.

Web A Broken Out Section Is Easy To Do On A Drafting Board, And Hard To Do In 3D Cad Like Solidworks.

Web 3.13 hidden lines and centerlines. Web the dashed line is used to indicate hidden details like hidden outlines and hidden edges. Web visible lines represent the visible edges, boundaries, and outlines of objects in engineering drawings. Hidden lines are light, dashed, narrow, and short.

Web Hidden Lines (Thin) Type Lines Consist Of Thin Short Dashes, Closely And Evenly Spaced.

The dashed line may be either thick or thin, but only one type (thick or thin) should be used on a single drawing or set of drawings. In my first semester of university, i had my intro to engineering drawing class. My understanding is that should and shall are used deliberately in standards, with a precise grammatical meaning. Hidden lines are 0.3 mm thin dashed line.

“Sketching” Generally Means Freehand Drawing.

1) always show all hidden lines unless it creates too much clutter. 2) never use hidden lines unless it helps to clarify the shape of the part (in other words, if the the part is defined with, say, 3 or more views/sections and those views are enough to clarify the shape of the part. Cutting plane lines are used in section drawings to. Figure 3.46 shows a case in which hidden lines are needed because a projecting part cannot be clearly shown without.
