What does it mean if a drawing is not to scale?
On plans, maps, and engineering drawings it means that you should not measure a length on the document and then expect to be able to calculate the “real life” distance from it.
What is not scaled dimensions?
When you override the value of a driven dimension by editing its dimensional value, the dimension is not-to-scale. For example, if you override the dimensional value that is 15 millimeters (A) to be 30 millimeters, the actual size of the line that you see would still be 15 millimeters (B).
What is the symbol for no scale?

What does it mean not to scale?
“To scale” means one inch in real life equals one inch in your drawing. So “not to scale” means the drawing is larger or smaller than real life. A sculpture that is larger than reality is “monumental”.
When a drawing is to scale what does it mean?
When a drawing is described as ‘to scale’, it means that each element in that drawing is in the same proportion, related to the real or proposed thing – it is smaller or indeed larger by a particular percentage.
What does NTS mean on drawings?
NTS – Not To Scale. Anything drawn with a “NTS” next to it means that whatever you do, you should not get a physical scale out to measure anything. Read the text and ignore the dimensions and relative relationships of what is drawn.
What is the fuse symbol?
Fuse (electrical) A miniature time-delay 250 V fuse that will interrupt a 0.3 A current at after 100 s, or a 15 A current in 0.1 s. 32 mm (1 1/4″) long. Type Passive Working principle Melting of internal conductor due to heat generated by excessive current flow Electronic symbol Electronic symbols for a fuse.
What are engineering symbols?
For example, engineering symbols are used in technical drawings to convey the specific geometry and other details about pieces of equipment or components. To limit errors caused by personal interpretation, engineering drawings and diagrams are governed by standardized language and symbols.
How do you read engineering drawing symbols?
They are often in the bottom right-hand corner of the drawing/part.Information Blocks The name and address of the company who produced/ owns the drawings. The part number and description. Mass. Material. General tolerances. Units. Finish. Projection details.
What does scaling something mean?
transitive verb. 1 : to remove the scale or scales from (as by scraping) scale a fish. 2 : to take off in thin layers or scales scale tartar from the teeth. 3 : to throw (something, such as a thin, flat stone) so that the edge cuts the air or so that it skips on water : skim.
What do you think the scale tells us?
The scale tells us how lengths on the drawing relate to lengths on the actual object. For example, in the basketball court activity, we saw that 1 centimeter on the drawing represented 2 meters of actual distance on the actual court. If we have a scale drawing, we can use the scale to find lengths on the actual object.
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 does a 1/100 scale mean?
Ratio scales If the scale of the plan is 1 : 100, this means the real measurements are 100 times longer than they are on the plan. So 1 cm on the plan represents a real length of 100 cm (1 metre).
What does NTS stand for?

How do you manually scale a drawing?
How to Scale Things Down for a Drawing Measure the objects that you want to draw. Write down your notations. Scale the items by use of ratios. Divide the 10 by the measured length of the wall, 120, which looks like this as a fraction: 10/120. Set up a ration for the height of the wall, too.
How do you reduce scale?
When scaling down, divide the original measurements by the second number in your ratio.Convert the actual measurements with the ratio. Some ratios may be irregular, like 5:7. For example, if scaling down with a 1:2 ratio, a length of 4 inches (10 cm) would become 2 inches (5.1 cm) because 4 ÷ 2 = 2.
How do you convert scales to drawings?
Drawings can be scaled up or down using either a calculator or a scale rule. To scale a drawing using a calculator: divide the measurement by the scale if you want to reduce the drawing in size, or. multiply the measurement by the scale if you want to increase it in size.
How do I fix scale in AutoCAD?
How to scale down in AutoCAD – Window select the object(s) in AutoCAD, type SCALE, and then specify a number between 0 and 1. Hit Enter. The size of the object(s) will SCALE DOWN by that factor. How to scale up in AutoCAD – Window select the object(s), type SCALE, and then specify a number larger than 1.
Why are my dimensions wrong in AutoCAD?
Check the units of the drawing are set correctly (enter the UNITS command). The units may have been changed from when the drawing was originally created. Check objects for Elevation or Start Z / End Z values (via Properties palette). Dimensioning from 2D to 3D space can throw off values.
What is NTS scale?
Some drawings (such as isometric drawings) are Not To Scale (NTS). You can still count the points and specify the length for measurements on NTS drawings.
What does not to scale mean in math?
It means that they did not draw everything exactly the right size. If a map is drawn to scale, you can take a ruler out, measure things, and figure out how far away they are. If it’s not drawn to scale, then it’s just a picture showing how things are positioned relative to each other.The same thing is true in math.
Why do drawings plans are divided into different sheets?
That was possible because little detail was included, the building techniques involved being common knowledge amongst building professionals. Modern working drawings are much more detailed and it is standard practice to isolate select areas of the project on separate sheets.
