If you want your printed scale to be 1 inch = 100 feet, your scale factor ratio is 1:1200. For example, if you plan to print your drawing atġ/8 = 1 -0, your scale factor ratio is 1:96 (1/8 = 12 is the same as 1 = 96). For example, when you draw text, you need to determine the text size so that when you print it later at a particular scale, the text height is correct.Īfter you determine the eventual scale of your finished drawing, you can calculate the scale factor for the drawing as a ratio of one drawing unit to the actual scale unit represented by each drawing unit. You can set up annotation scaling to control the scale of entities such as text, arrows, and linetypes, or you can make manual adjustments when you first set up your drawing so that annotations print and display at the correct size. Scale, however, does affect the way a few elements such as text, arrows, or linetypes print or plot and even display in your drawing. When you print your drawing, you can assign the scale at which the drawing is to print. For example, when you draw a mechanical part 40 inches in length with progeCAD, you actually draw it as 40 inches, rather than applying a scale factor as you draw. Although its a good idea to keep your scale factor in mind when setting up a drawing, you dont need to set the scale until you print it. Instead of drawing to a particular scale, you draw everything in the program full-size.
