Why are different views like orthographic, isometric, and sectional important in engineering drawings? Web hidden lines (figure 4) are used to show edges and surfaces that are not visible in a view. Hidden lines are 0.3 mm thin dashed line. Hidden lines in a drawing represent the edges where surfaces meet but are not directly visible. They are an essential part of.
Iii basic components of an engineering drawing. These lines are drawn as thin, evenly spaced dashes. Web table of contents hide. Often they are omitted in an isometric view.
These types of lines also known as object lines. Web hidden lines, as you already know, are used to represent features that cannot be seen in the current view. 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.

Web what are the most important types of lines i should know in engineering drawing? Hidden features behind the cutting plane are omitted, unless required for dimensioning or for definition of the part. Web the fourth type of line used in engineering drawing is the hidden line. 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.

There Are Also Lines Used In Some Particular Cases:
A variety of line styles graphically represent physical objects. They are 0.6 mm thick. A sectional view represents the part of an object remaining after a portion is assumed to have been cut and removed. These lines are drawn as thin, evenly spaced dashes.
Web thick or thin dashed line. Web hidden lines (thin) type lines consist of thin short dashes, closely and evenly spaced. Hidden features behind the cutting plane are omitted, unless required for dimensioning or for definition of the part. They are dark and thick lines of any engineering design drawing. It is more than simply a drawing, it is a graphical language that communicates ideas and information.
