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..

Are construction lines thick?

Line weight is the thickness of the line. Construction lines and guide lines are very light, easily erased lines used to block in the main layout. Visible lines are the edges or “outlines” of an object. They are drawn as solid lines with a thick/heavy weight.

What is line and types of lines?

There 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. Let’s look at each one of them.

What is the leader line?

A leader line is a line that establishes a connection between a graphical representation of an item and some text. A leader points to a bit of our drawing and says: ‘Oi – Look Here’ and ‘Read This! … The leader line itself should be a continuous Thin line (see this post on Linetype Definitions).

What are the lines on a blueprint called?

Phantom lines (see Figure 1-6) are thin lines used to indicate alternate positions of the parts of an object, repeated detail or the locations of absent parts. They are made by alternating one long and two evenly- spaced, short dashes, with a long dash at each end.

What is the importance of alphabet of lines?

Why is it important to recognize the alphabet of 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.

What is the purpose of an object line?

Object lines? The purpose of construction lines is to give you an outline of what you are about to draw. Object lines are used for outlining the shape and giving it its main features.

What is center line?

: a real or imaginary line that is equidistant from the surface or sides of something.

What does a hidden line look like?

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. … The hidden portion of the line is drawn using a hidden-line pattern, and the visible portion of the line is drawn using a solid line.

What are the different alphabet of lines?

ALPHABET OF LINEOBJECT OR VISIBLE LINES – Thick dark line use to show outline of object, visible edges and surfaces.CONSTRUCTION LINE – Very light and thin line use to construct layout work.DIMENSION LINE – Thin and dark lines use to show the size (span) of an object with a numeric value.More items…

What is the heaviest line in a drawing?

The heaviest line weight indicates the ground line cut. The next heaviest line weight “profiles the planes closest to the plane of projection” (Ching & Juroszek, 1998, p. 152). Medium line weight indicates distance from picture plane, progressively getting lighter to describe objects further from the picture plane.

What are the five basic types of lines?

There are 5 main types of lines in art: vertical lines, horizontal lines, diagonal lines, zigzag lines, and curved lines. Other types of lines are simply variations of the five main ones.

How are construction lines drawn?

To draw a construction line, first specify a single datum point through which the construction line will pass. After the datum point is specified, additional construction lines can be drawn through the same datum point. There is no limit to how many construction lines can be created.

What is a 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.

What is the solid black line called?

1 Object Lines and Hidden Lines. The outline of the object is a solid black line called an object lineA solid black line that defines the outline of an object..

What are the 4 types of lines?

In Geometry, there are basically four types of lines….They are:Horizontal Lines.Vertical Lines.Parallel Lines.Perpendicular Lines.

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 is the object line?

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