Quick Answer: What Are The Lines Used In Drawing?

How do I find hidden lines in an object?

A drafter—in deciding whether a line in a view should be represented as hidden or as visible—relies on the fact that in third-angle projection the near side of the object is near the adjacent view, but in first-angle projection the near side of the object is remote from the adjacent view..

What are lines?

What is a line? 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. Fun Facts.

What are the uses of line?

The Uses of Line Line can control an viewer’s eye. It can describe edges. It can indicate form as well as movement. It can also indicate value and a light source in drawing.

What are alphabet lines?

The Alphabet of Lines is a list of line symbols that engineers use in technical drawings to communicate specific shapes, sizes or surfaces. In the Alphabet of Lines, thick, dark lines represent the outline of an object, showing its visible surfaces and edges.

What are the 3 types of lines?

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

Are all lines straight?

Straight and curved lines A line can be straight or curved. In geometry, the word line means a straight line. … A straight line is the line traced by a point moving in a direction that does not change. A curved line is sometimes called a curve.

Where do you put hidden lines?

Hidden lines are used to show surfaces that are not directly visible. All surfaces must be shown in all views. If an edge or surface is blocked from view by another feature, it is drawn using a hidden line. Figures 4-11 and 4-12 show objects that require hidden lines in their orthographic views.

What are the three regular views?

Although six different sides can be drawn, usually three views of a drawing give enough information to make a three-dimensional object. These views are known as front view, top view and end view. Other names for these views include plan, elevation and section.

What are hidden lines in drawing?

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. Sometimes they are used to make a drawing easier to understand. Often they are omitted in an isometric view. Section Line.

What are the 7 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 are the lines drawn called?

Straight lines may be drawn in different directions and are given three names. (i) Horizontal lines: The lines drawn horizontally are called horizontal lines. (ii) Vertical lines: The lines drawn vertically are called vertical lines.

What are the two types of line?

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.
