Hidden Lines In Engineering Drawing
Hidden Lines In Engineering Drawing - Hidden lines, as you already know, are used to represent features that cannot be seen in the current view. Section lines, or hatching, that represent the cut surface usually consist of thin parallel lines, as shown below, drawn at an angle of approximately 45° to the principal edges or axes of the part. Types of lines include the following: Visible lines are dark and thick. Web all hidden lines behind the cutting plane must not be shown, but all visible lines should be shown! Their basic purpose is to show circular/cylindrical features in a drawing, which are found in abundance in mechanical parts. These features are typically inside the object or obscured by other surfaces. Web standard engineering drawing line types. Web there are 12 types of lines usually used in engineering drawing. 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. Web in an isometric drawing, the object’s vertical lines are drawn vertically, and the horizontal lines in the width and depth planes are shown at 30 degrees to the horizontal. These types of lines also known as object lines. As the name suggest, they are visible in an engineering drawing. Why not just use a 3d model?

Figure 3.46 shows a case in which hidden lines are needed because a projecting part cannot be clearly shown without them. Web thick or thin dashed line. Curved lines (arcs, circles, and ellipses) cutting plane lines. When an object becomes more complex, as in the case of an automobile engine block, a clearer presentation of the interior can be made by sketching the object as it would look if it were cut apart. They are drawn as short dashes that are equally spaced. They are dark and thick lines of any engineering design drawing. 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. Their basic purpose is to show circular/cylindrical features in a drawing, which are found in abundance in mechanical parts. Dimensions should be shown in true profile views and refer to visible outlines. It is more than simply a drawing, it is a graphical language that communicates ideas and information.2020 Drawing Hidden Lines for an Orthographic drawing using alignment
