Which type of scale is engineer scale?
Engineer, or civil, scales, such as 1˝ = 10´ or 1˝ = 50´, are used for measuring roads, water mains, and topographical features. The distance relationships also may be shown as 1:10 or 1:50. 2. Architect scales, such as 1/4˝ = 1´-0˝ (1/48 size) or 1/8˝ = 1´-0˝ (1/96 size), are used for structures and buildings.
How many types of scales are there?
Introduction: There are 4 types of scales, based on the extent to which scale values have the arithmetic properties of true numbers. The arithmetic proper- ties are order, equal intervals, and a true zero point. From the least to the most mathematical, the scale types are nominal, ordinal, interval, and ratio.

What are scales in technical drawing?
A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount (called the scale). The scale is shown as the length in the drawing, then a colon (“:”), then the matching length on the real thing.
What does a 1/4 scale mean?
A 1/4″ scale means that each 1/4″ (inch) on the plan counts for 1′ (feet) of actual physical length. To scale a blueprint in imperial units to actual feet. multiply the measurement on the drawing (in inches decimal equivalent) with the denominator.

How many types of scales are there according to dimension and length?
These measurement scales are four in number, namely; nominal scale, ordinal scale, interval scale, and ratio scale.
What are the 5 types of scales?
In Statistics, the variables or numbers are defined and categorised using different scales of measurements.Levels of Measurements Nominal Scale. Ordinal Scale. Interval Scale. Ratio Scale.
What is scale and its types?
The Four Scales of Measurement. Data can be classified as being on one of four scales: nominal, ordinal, interval or ratio. Each level of measurement has some important properties that are useful to know. For example, only the ratio scale has meaningful zeros.
What are the different types of weighing scales?
There are two main categories of scales: mechanical and digital. Mechanical scales: The mechanism of mechanical scales vary, but most commonly use a spring. The weight is applied and the measurement is shown by a moving dial. Digital scales: This type of scale employs the use of a special electrical circuit.
What are the 7 types of lines?
Points, Lines and Angles. Horizontal Lines. Vertical Lines. Parallel Lines. Perpendicular Lines. Some Other types of Lines in Maths.
What are the different types of drawing instrument used in engineering drawing?
The instruments used in engineering drawing are: Drawing sheet. Drawing board. Mini drafter. T square. Compass. Divider. Set squares. Clinograph.
What are the three types of engineering drawings?
Listed are detail drawings, assembly drawings, schematic drawings, and many other content specific drawing types.
What are three types of scale in architecture?
Typically, architecture deals with different types of scale: Human scale: The human interaction with environments based on physical dimensions, capabilities and limits. Intimate scale: This is a smaller, more personal scale.
How many types of pencils are used in engineering drawing?
Generally for technical drawings, the three grades of pencil used is HB, H and 2H . For different purposes, different grades of pencils are used.
What is scale example?
Scale is defined as a system or series of marks used for measuring or registering. An example of scale is what someone would use to figure out the length of something. An example of scale is what someone would use to find out how much they weigh. noun. 12.
What is 12th scale?
1:12 scale is sometimes called one-inch scale and means 1 foot (or 12 inches) on a real item that has been scaled down to 1 inch. If you measure the ceiling in your house and it’s 10ft, it would be 10in in the dolls house.
What is a 1/6 scale?
Items in 1:6 scale, also known as “Playscale” or “Fashion Doll” scale, are sized to fit with common fashion dolls such as Barbie or collectible action figures, principally military action figures. In this scale, 1 inch is equivalent to 6 inches in full size.

What is RF explain the types of scale?
A representative fraction (RF) is the ratio of distance on the map to distance on the ground. An RF of 1:24,000 means one inch on the map equals 24,000 inches on the ground and one centimeter on the map equals 24,000 centimeters on the ground. RFs are easy to determine and to insert in ArcMap.
What is rf of scale?
Representative Fraction (R.F.): scale is a ratio, or fraction, that expresses the mathematical relationship between MAP and LAND.
Where is diagonal scale used?
Diagonal scale is used in engineering to read lengths with higher accuracy as it represents a unit into three different multiple in metres, centimeters and millimeters. Diagonal scale is an important part in Engineering drawings.
