Scale cartoon
Calibration drawings are used to illustrate items that information technology is not useful or convenient to draw at their actual size
This may be because drawing the detail at full size would be unmanageable, or would non easily fit on a single canvass of paper (such as a building), or alternatively considering items need to be drawn larger than full size to adequately represent all the detail that needs to exist communicated (such as a circuitous connection).
The scale of drawings is described every bit a ratio using the notation:
A distance at full size : The altitude at the scale used that would be the same length.
For example:
- A full size drawing would be i:i (or sometimes 1/1 or 'one to one').
- A half size drawing would be 1:2.
- A 10th size drawing would be 1:ten.
- A double size drawing would be 2:1.
In the construction manufacture a range of scales are generally used depending on the nature of the drawing. For example:
- A location plan at 1:thousand.
- A site plan at 1:200.
- A floor programme at 1:100.
- A room plan at 1:50.
- A component drawing at 1:5.
- An assembly drawing at 1:ii.
It is of import that the scale used is noted on the drawing. In addition, because of the ease of reproducing, press and re-sizing drawings, information technology is of import to note the original sheet size that the scale was drawn at, so for example A4, A3, A2, A1, A0, and so on.
In some cases, information technology may exist appropriate to use more than one scale on a unmarried drawing, for example, to show the elevation of land across across a significant distance. In this example, differences in pinnacle might be illustrated at a larger scale and a smaller scale used for horizontal distances. Hither, the scale might be noted on the axes of the drawing, or actual distances shown on the axes.
In other cases a scale might apply more than one unit of measurement. For instance, the length of an arrow on an air flow diagram might represent the velocity of the air, due east.grand. 1 cm = 0.one thousand/south.
The utilize of computer aided drawing (CAD) and building information modelling (BIM) has introduced a new concept to this procedure, equally in this case, digital models are created at full size. Drawings of whatsoever calibration tin then exist generated from the model.
