Hidden Lines In Engineering Drawing

Hidden Lines In Engineering Drawing - 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. The question of whether to dimension to hidden lines came up a few weeks back and i think the reference given was slightly wrong. Web hidden lines in a drawing represent the edges where surfaces meet but are not directly visible. (1) visible lines, (2) hidden lines, (3) center lines. Hidden lines are 0.3 mm thin dashed line. Their basic purpose is to show circular/cylindrical features in a drawing, which are found in abundance in mechanical parts. 1) always show all hidden lines unless it creates too much clutter. 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. In the example above, a visible edge and hidden edge both project to the same line, so a. Hidden lines will always begin and end with a dash.

Hidden lines will always begin and end with a dash. 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. 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. Figure 3.46 shows a case in which hidden lines are needed because a projecting part cannot be clearly shown without them.
