Construction lines (also known as xlines) are temporary linework entities that can be used as references when creating and positioning other objects or linework. Construction lines are either circles or straight lines that extend to infinity in both directions.
What is constructive line in art?
Contour lines are a continuous line that defines the outline of a shape. They can exist outside and inside a shape, or a figure and are often referred to as line art. Some artists create contour lines by using the same width line, while others change the width to give more energy and volume suggestions.
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. The new lines are confined to the area that was visible when the lines were created.
Are construction lines necessary?
Once your hand and mind are trained, these lines won’t be as necessary, although even the most accomplished artists lightly draw construction lines for helpful reference. Unless you are drawing from a vantage point directly facing one of its sides, any building will show how drawing construction lines can help.
What is the difference between the line and the construction line?
Lines that extend to infinity in one or both directions, known as rays and construction lines, respectively, can be used as references for creating other objects. A construction line (also known as an xline) is a linear object that passes through two points and extends to infinity in both directions.
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. Construction lines are either circles or straight lines that extend to infinity in both directions.
What is the purpose of the construction 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.
Are construction lines thick or thin?
OBJECT OR VISIBLE LINES – Thick dark line use to show outline of object, visible edges and surfaces. What is this? 2. CONSTRUCTION LINE – Very light and thin line use to construct layout work.
What are the types of line in art?

Which of the following is used in drawing a construction line?
Explanation: Initial work and construction lines are drawn using H pencil. 2H pencil is used for outlines, dotted lines, dimension lines and arrowheads. 3H, 4H are used for centre lines and section lines.
Are construction lines dotted?
In drafting, continuous lines of various weights are used to represent objects and major elements such as structural walls and columns. Dotted lines are usually used to denote objects hidden from view. They are also used to show objects above the cutting plane of a floor plan, such as wall cabinets, beams, arches, etc.
What is the line types of line?
Types of Line Horizontal Lines. Vertical Lines. Parallel Lines. Perpendicular Lines.
Is used for light construction line?
Hard pencil leads are used for drawings, light layouts, and drawings requiring a high degree of accuracy. These leads are used for sketching, architectural line work, lettering and general purposes.
What are object lines in drawing?
A visible line, or object line is a thick continuous line, used to outline the visible edges or contours of an object. 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.
What is an expressive line in art?
Expressive lines are curved, adding an organic, more dynamic character to a work of art. Expressive lines are often rounded and follow undetermined paths. Indeed, the sculpture seems to be made up of nothing but expressive lines, shapes and forms.
What is the purpose of construction lines object lines what is the purpose of hidden lines and center lines?
Object lines are used for outlining the shape and giving it its main features. What is the purpose of hidden lines and center lines? The purpose of hidden lines is to show where other faces exist that are not seen. Center lines show the diameter of circles in a sketch.
Which pencil is best for drawing construction lines?
Pencils Grade of Pencil Used to Draw 3H Construction lines 2H Dimension lines, center lines, sectional lines, hidden lines H Object lines, lettering HB Dimensioning, boundary lines.
What is a match line in construction drawings?
A match line is a line on a design drawing that projects a location or distance from one portion of the drawing to another portion of the drawing.
Why is line weight and symbol important on a construction drawing?
To add legibility and clarity to a dense drawing. Using different line weights allows you to distinguish one type of information from another, and to guide how the eye moves around the drawing – both elements which are key to achieving legibility and clarity.
What do construction drawings include?
They are the pictorial record of the official design for the building, and generally include detailed depictions of every element of the finished building including the foundation, floor, walls, elevations, interior details and elevations, cabinetry, MEP design, structural details, and ceiling plans.
What is dimensional line?
The dimension line is a fine, dark, solid line with arrowheads on each end. It indicates direction and extent of a dimension. In machine sketches and drawings, in which fractions and decimals are used for dimensions, the dimension line is usually broken near the middle to provide open space for the dimension numerals.
What is construction sculpture?
This month’s Art Center display focuses on constructed sculpture — sculpture assembled from pieces of wood, metal, cardboard, or other materials. This form of sculpture is believed to have originated with Pablo Picasso in the early 1900’s, and has since become a popular sculptural technique.
What is a geometric line in art?
Geometric lines are ones that relate to perfect mathematical shapes and man-made objects. They are straight, regular and uniform. They often follow a specific pattern and can be symmetrical or repeat in a specific way.
