What are object lines in drawing?
Object lines (Figure 3) are the most common lines used in drawings. These thick, solid lines show the visible edges, corners, and surfaces of a part. Object lines stand out on the drawing and clearly define the outline and features of the object.
What does an object line show on a 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.
How are hidden lines represented on a drawing?
It is standard practice to use dashes to represent any line of an object that is hidden from view.
What are the types of lines in drawing?
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.
What are lines in technical drawing?
Lines in technical drawings are part of a specialized graphic language that is standardized throughout industry. Each type of line has a very precise symbolic meaning. Correct usage of this “alphabet of lines” is essential whether you use traditional drafting methods or CAD. Line weight is the thickness of the line.
Why do we need to know the alphabet of lines and drawing symbols?
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 type of lines can be used in a drawing to show that part of an object has been removed?
There are two types of break lines, long break lines and short break lines. Both show that part of an object has been removed. This is often done when a long uniform object needs to be shortened to fit the drawing page.
What do hidden lines represent?
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.
What do hidden lines represent on Multiview drawings?
would appear as hidden lines in an orthographic multiview drawing? These are the three views associated with the object you just built. Hidden lines are dashed lines used to represent internal features that are obscured by the object.
What different lines represent in art?
Horizontal lines indicate a sense of motionless rest and peace. Vertical lines are seen as tall and represent grandeur. Horizontal and vertical lines used together in a square or rectangular shape convey structure and represent stability. Diagonal lines move the eye in a direction and indicate movement and fluidity.
How do you describe lines in art?
Line- Line is defined as a point moving in space where its length is greater than its width. Lines can be two or three dimensional, implied or abstract. Different types of lines include continuous, broken, jagged, vertical, horizontal, or diagonal. Lines are the foundation of drawing.
What are the lines used in engineering drawing?
Following are the different types of lines used in engineering drawing: A type – Continuos Thick. B type – Continuous THIN. C type – Continuous THIN Freehand. D type – Continuous THIN Zig-Zag. E type – Dashes THICK. F type – Dashes THIN. G type – Chain Thin. H type – Chain THIN and THICK.
What are the 4 types of lines?
Types of Line Horizontal Lines. Vertical Lines. Parallel Lines. Perpendicular Lines.
What do thick lines represent in art?
They suggest strength and give emphasis to nearby elements. Thick lines are bold and make a statement. Horizontal lines are parallel to the horizon (hence the name).
What are the difference between short lines and long lines in terms of drawing?
Short lines are drawn with finger movement while long lines are made with arm movement. Long lines, however, may be drawn in segments with very small spaces or gaps between segments. Parallel lines may be vertical, horizontal, or inclined. Lines may be drawn in various thicknesses or weights with a soft pencil.
Which line used to present alignment or a hidden part of the object in a drawing?
What is a “Section View” ? A section view is a view used on a drawing to show an area or hidden part of an object by cutting away or removing some of that object. The cut line is called a “cutting plane”, and can be done in several ways.
How it is important in technical drawing?
Technical drawing is essential for communicating ideas in industry and engineering. To make the drawings easier to understand, people use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page layout. Technical drawings are understood to have one intended meaning.
Which of the following lines are used to show that the object is cut and then viewed?
Which of the following lines are used to show that the object is cut and then viewed? Explanation: Hatching lines are used to show that the orthographic view is drawn after a section of the object is cut. They indicate that the object is cut and it shows the remaining solid body.
How can alphabet of lines makes the work of engineers and designers easier?
Line symbols used in technical drawing are often referred to as ALPHABET OF LINES. The use of line symbols enables engineers/designers to express the 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 does Section AA mean?
A section removed from its normal projected position in the standard arrangement of views is called a “removed” section. Such sections are labeled SECTION A-A, SECTION B-B, etc., corresponding to the letter designation at the ends of the cutting plane line.
Which of the following lines used to indicate the part of the drawing to which a note refers?
Leaders are solid lines with one arrowhead and indicate a part or portion to which a note, number, or other reference applies. Break lines indicate that a portion of the object is not shown on the drawing. Short breaks are made by solid, freehand lines.
