What is the importance of lines?
Lines are used to create shape, pattern, texture, space, movement and optical illusion in design.
The use of lines allows artist to demonstrate delicacy or force.
Curves may take us slowly uphill, or turn sharply twisting our mind as they turn.
a line can express various moods and feelings..
Who invented lines?
Euclid described a line as “breadthless length” which “lies equally with respect to the points on itself”; he introduced several postulates as basic unprovable properties from which he constructed all of geometry, which is now called Euclidean geometry to avoid confusion with other geometries which have been introduced …
What are the 4 basic components of an engineering drawing?
The main purpose of engineering drawings is to communicate to other engineers, machinists, etc….Dimensions have four basic components:Dimension Text.Dimension Line andArrows.Extension Lines.Gap.
What are the 6 types of lines?
There are many types of lines: thick, thin, horizontal, vertical, zigzag, diagonal, curly, curved, spiral, etc. and are often very expressive.
How many type of line do we have?
four typesThere are four types of lines: horizontal line, vertical line, perpendicular, and parallel lines. They are defined based on their orientation, and the angles if any, formed between them.
What are the two types of lines?
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 uses of line?
The use of lines, or outlining, to create a sense of shape is most commonly used in cartoon style illustrations or animations. Another use of line in graphics is the ability to help suggest a tone or feeling in a work. Vertical lines can be used to create a sense of strength or stability.
What are construction lines?
Construction lines (also known as xlines) are temporary linework entities that can be used as references when creating and positioning other objects or linework. For example, you can use construction lines to prepare multiple views of the same item, or create temporary intersections to serve as object snaps.
What are the 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 are the types of lines and their uses?
Types of lines and their usesDesignating letterType of lineBContinuous – thinApplication: This is the line type you would use for dimension lines, projection lines, intersection lines, and headers. It’s also used for hatching and outlines of revolved sections.DContinuous – thin, ruled with zig-zag5 more rows
What are the different types of lines in engineering drawing?
The different line types are colored for clarity.Black = object line and hatching.Red = hidden line.Blue = center line of piece or opening.Magenta = phantom line or cutting plane line.
Who made the first straight line?
Thales was probably the first known scientist and engineer and is known for his advanced application of geometry which requires straight lines. The Romans were also good at creating long straight lines they used a device called a gromer for creating long and very straight roads.
What is a ray line?
A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray. A ray is named using its endpoint first, and then any other point on the ray (for example, →BA ).
What are lines?
A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.
What is a hidden line?
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.
What is standard line?
(Entry 1 of 2) : a railroad line or route upon which the regular or highest rates apply : a fast-service route in distinction from slower and perhaps longer routes or from one that is partly by rail and partly by water — compare differential route.
Are there perfect straight lines in nature?
There are no absolute continuums. There are no surfaces. There are no straight lines.” … Even the most ubiquitous, inescapable “line” in nature, the skyline, or horizon, is not a line at all, but a curve of such diameter that it can’t be discerned by the naked eye unless you’re, well, flying.
