The purpose of hidden lines is to represent edges that are not directly visible. The purpose of center lines is to represent the axes of circular features.
The hidden line is drawn, however, the edges of the center line can still be seen ( the center line ends up appearing as extra long dashes on either side of the end of the hidden line)
the line which is not seen
The short dotted lines are the type of lines on a drawing that are designed to represent the hidden details.
A circle has infinite lines of symmetry, any line going through the center is a line for symmetry.
Used for drawing horizontal lines. To support set squares when drawing vertical line and inclined lines.

On engineering drawings, the priority hierachy is object line, hidden line, center line. A centerline can be drawn extending beyond the physical edges of the part, a hidden line cannot. The hidden line (equally spaced short dashes) is drawn on the part instead of the centerline (alternating long dash, short dash, long dash)when the two lines are stacked in a view. If an object line, hidden line and center line are stacked in a view, the object line takes priority and is shown on the drawing. The centerline in both instances can be shown extending beyond the part edges for clarity.

Hidden lines are broken lines that indicate the lines not seen in a certain perspective.

In engineering drawing, there are several types of lines used to convey different information. Some common types of lines include object lines, which represent the visible edges and outlines of an object; hidden lines, which show edges that are not visible from a certain viewpoint; center lines, used to indicate the center of a cylindrical or symmetrical object; and dimension lines, which show the measurements of an object. Each type of line serves a specific purpose in communicating the design and specifications of an engineering drawing.
The "Alphabet of Lines" refers to the different styles of lines used in drafting such as to show different features about an object that is drawn: hidden. construction, cutting-plane, visible (object), dimension, extention, phantom, center, section, and border.AnswerIn Drafting, or Computer Aided Drafting (CAD) -- the alphabet of lines are the different lines that draftsmen, architects, engineers, et al use when constructing a drawing. For example, a thick solid line is called an object line and represents the outline of a part on a drawing. A dash line represents an edge that is not visible in a particular view, hence it is called a hidden line.Other common lines used in drafting include dimension lines, extension lines, construction lines, border lines, center lines, among many others depending on the type of drawing.
Horizontal, vertical, diagonal, curved, patterned, contour, implied, actual?
A circle has infinite lines of symmetry, any line going through the center is a line for symmetry.
Contour lines show elevation.
On a tennis court there are five lines. The line all the way at the back is the base line, the one in the front is the service line, the line making the T shape is the center service line, the first line on the left or right is the ally line, and the second line on the left or right is the side line.
