What does Diagram not to scale mean?
If you have to calculate using an image from a diagram remember to measure the distance accurately with your ruler. Then make a note of the scale of the diagram that will be given to you. You can then use this information to calculate the real distances or sizes.
If you are comfortable with reading chord diagrams, the format is exactly the same. All that changes is what you actually do with the information. With a chord diagram, you play all the notes at the same time. With a scale diagram, you play each note one by one.
By drawing not to scale, means giving an assumption such as 1 cm is to 100 m and taking that into consideration when drawing. Your diagram will be much smaller in size. We call that ratio to ratio size. That means you are not supposed to take measurements from it.
The scale tells us what some length on the scale drawing represents in actual length. For example, a scale of “1 inch to 5 miles” means that 1 inch on the drawing represents 5 actual miles.
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.
1 : an instrument or machine for weighing. 2a : a beam that is supported freely in the center and has two pans of equal weight suspended from its ends —usually used in plural. b : either pan or tray of a balance. scale. verb (1)
You have to divide your real measurement to the model. For example, if your real measurement is 5m and your model is 20cm, divide 5/20 =1/4 and that means the ratio would be 1:4.
“Do not scale” means that there are sufficient dimensions stated to locate all dimensions – just have to read the drawing correctly.
Its a way of saying that the geometry on the drawing may not be true to what the dimensions state.
Adjective. not-to-scale (not comparable) Presented at a size other than to-scale. The sketch is a not-to-scale drawing of the workpiece with cut surfaces highlighted by heavy lines.
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.
It means the diagram shown is not exact to the measurements given. For example, if it’s something like a square or rectangle that shows that one side is about 3 cm but it says ‘not drawn to scale’, it means that that side is not actually 3cm/drawn accurately. See a translation. 1 like.
