What you really need to know! A scale drawing represents something that is too large or too small to be drawn at actual size.

What you really need to know! A scale model can be used to represent something that is too large or too small for an actual-size model.

What you really need to know! The scale gives the relationship between the drawing/model measure and the actual measure.
