Simply divide the needed world drawing area’s length and width by the dimensions of the sheet. If you are printing on an US Letter sized sheet, then AutoCAD will assume youre units are in inches You will need to print your square at a scale of 100/254 for an ansi or english paper size or 10:1 for an ISO paper size. Reversely, if you know the sheet size and the world size of what you are going to draw, you can find the largest plot scale you can use. If you know the desired sheet size and the drawing scale factor, you can calculate the available drawing area with zero hassle. You have to narrow your choice based on the standard of your industry. The selection of a particular sheet size is based on the common practices in your industry. Having an opinion about the paper size is crucial to the Drawing scale you are using while designing. You can find in the following table some common Drawing scale and Drawing scale factor that you might make use of while working with AutoCAD Drawing Scale and Scale factor Drawing Scale The Drawing Scale factor of a drawing is the conversion factor between a measurement on the plot and the measurement in the real world. In some drawings, data in model space hasn't been drawn at a 1:1 scale. The drawings are then plotted or printed at a plot 'scale' that accurately resizes the model objects to fit on paper at a given scale such as 1/8' 1'. In other words, a 12-foot wall is drawn at that size. The Drawing Scale factor is a single number that represents a multiplier. AutoCAD 2D drawings are commonly drawn in model space at a 1:1 scale (full-size). Let’s take this as an example: Drawing scale 1:10 simply means that 1 unit on the plotted drawing corresponds to 10 units in the real world. Drawing Scales are expressed with / or: such as 1/2 or 1:100. The Drawing Scale has been around since the beginning of technical drawing and on-paper graphic representation of objects. There exist a set of standard of Drawing Scale and Drawing Scale factor acceptable for the discipline you happen to work in.ĬAD users use two different terms while talking about a drawing intended to be plotted: Drawing Scale and Drawing Scale Factor What does scale factor mean?Ī scale factor is simply a factor by which a drawing is scaled. You need to be able to draw while having in mind the relationship the object in the real-world and the object plotted on paper will have.įor a real project, you should not just come up with some arbitrary scale based on what looks normal on whatever paper size you want to plot on. When working on a project, it is necessary to select the scale at which you will eventually plot the drawing. This is a very important topic when it comes to working on a project destined for either implementation or team-work.
