What Do You Understand By Thickness Of Line?

What are the five basic types of lines?

There are five basic kinds of lines: Curved, Vertical, Horizontal, Zigzag and Diagonal.Curved lines change direction gradually to form curves, spiral and circles.Vertical lines move straight up and down and are perpendicular to the horizon.More items…•.

What line means?

In geometry, a line can be defined as a straight one- dimensional figure that has no thickness and extends endlessly in both directions. It is often described as the shortest distance between any two points. Here, P and Q are points on the line.

What is the purpose of a visible line?

The visible object line (also visible line) is used to outline the visible edges of the object being drawn. They should be drawn so that the views stand out clearly on the drawing.

Do lines have thickness?

A line is defined as a line of points that extends infinitely in two directions. It has one dimension, length. … A plane extends infinitely in two dimensions. It has no thickness.

How many types of line are there?

How many types of lines are there? There are two basic lines in Geometry: straight and curved. Straight lines are further classifies into horizontal and vertical. Other types of lines are parallel lines, intersecting lines and perpendicular lines.

What are the 7 types of lines?

They are:Horizontal Lines.Vertical Lines.Parallel Lines.Perpendicular Lines.

What are the 3 types of lines?

Types of LinesVertical lines: are straight up and down and perpendicular to horizontal lines.Horizontal lines: are straight up and down and perpendicular to vertical lines.Diagonal lines: are lines that straight in any direction except vertical or horizontal.More items…

What is an example of a horizontal line?

An equation that only crosses the y-axis is a horizontal line. … For example: y=5 is a horizontal line that crosses the y-axis at (0,5).

What is the name of horizontal and vertical lines?

X-axis and Y-axis are horizontal and vertical lines drawn to determine the position of point in the cartesian plane.

What is the meaning of visible line?

A visible line, or object line is a thick continuous line, used to outline the visible edges or contours of an object.

What is the horizontal line?

Anything parallel to the horizon is called horizontal. As vertical is the opposite of horizontal, anything that makes a 90-degree angle (right angle) with the horizontal or the horizon is called vertical. So, the horizontal line is one that runs across from left to right.

What are alphabet lines?

The lines in the Alphabet of Lines are used to describe shape, size, hidden surfaces, interior detail, and alternate positions of parts. Each conveys a particular meaning on the drawing.

Why is it called alphabet of lines?

Line symbols used in technical drawing are often referred to as ALPHABET OF LINES. The use of line symbols enables engineers/designers to express features of designed products clearly and accurately. Line features vary not only by width but also by how they are graphically represented in a drawing.

What are the different types of lines in drafting?

Three types of linesVisible or Object Lines. Dark thick lines that show the outside edges of an object.Construction Lines. Light lines that are drawn to help place other lines on a drawing. … Hidden Lines. Dashed lines that show parts of an object that cannot be seen from the current viewing angle.

What is the thickness of extension line?

Explanation: Out lines, dotted lines and cutting plane-lines are drawn using 2mm thickness lines. Whereas centre lines, section lines, dimension lines, extension lines, construction lines, leader lines, short break lines and long-break lines are drawn using 1mm thickness lines.

What are the six types of lines?

There are many types of lines: thick, thin, horizontal, vertical, zigzag, diagonal, curly, curved, spiral, etc. and are often very expressive.

What is the line weight?

Line weight is the visual lightness, darkness, or heaviness of a line within a drawing. In any architectural drawing, from a sketch to a construction drawing, the interplay of different relative line weights is used to communicate depth, importance, and proximity.
