Full-size scale: 1:1 means that the dimensions in the drawing are one-to-one to the real-world object.Enlargement scale: 2:1 means that for every unit in the real world, there are 2 units in the drawing.Reduction scale: 1:200 means that for every 200 units in the real world, there is 1 unit in the drawing.To simplify calculations, one of the two numbers (left or right) is equal to 1 (depending on the type of scale). Both numbers are separated by a colon (“:”). The scale is represented by a number for the dimensions in the drawing, followed by a number representing the real dimensions of it. In this sense, a scale is a ratio (a proportion) that can be classified into three different types: scale-up (enlargement), scale-down (reduction), or full-size scale (same as the real-life dimensions). A scaled drawing helps understand the details of an object in terms of length, width, height, and spatial relations. The scale remains the same for all the dimensions. 4 Methods for SCALING a drawing in AutoCAD in the LAYOUT sectionįor design purposes, a scale is a set of numbers used to measure or compare the dimensions of a real object represented in drawings.Ī scaled drawing refers to a graphic representation of an object in which each dimension is enlarged or reduced in a given proportion (scale).3 Methods for SCALING a drawing in AutoCAD in the MODELING section.
