To find the scale factor for architectural scales a little algebra is used. Once the scale factor is determined you will also use the value to set the DIMSCALE, and LTSCALE (AutoCAD variables).įor engineering scales the scale factor is the same as the scale. A scale factor can be determined based on the scale that the drawing will be displayed at. This complicates the sizing of text and symbols that are inserted model space must be scaled up. Your drawings are always drawn at full scale in AutoCAD’s model space. To ensure your drawing notes, labels and text are legible it is critical that you adhere to the standards of text heights and scales.
