We have also drawn our 9-unit line as described in the steps above, which appears at the bottom center portion of the drawing.Д¬ompare the length of your line with the size of any object in your drawing whose actual size you know. The example drawing below contains our correctly scaled trees, a few correctly scaled cars, and our incorrectly scaled tiny tree to the right. To determine the actual unit setting (inches, feet, meters, etc.), you can now perform a visual test by comparing the length of this line with an object in the drawing of a known size. You now have a line in your drawing that is 9 units long. Press the Enter key and then ESC to exit the LINE command. Now type 9 (do not click to continue the line).

Click anywhere in your drawing to start the line, and drag the cursor in any direction.

The Command line will prompt you to Specify first point. Here's a simple trick to check the units in AutoCAD:ДЇirst, draw a line: Type Line in the Command line. You may have even unknowingly switched the units or scale of your own drawing at some point. You may have received a drawing from a colleague, consultant, or client who previously set the units as, say, architectural inches, while you've meanwhile been working in decimal feet. What does this mean for you as the designer? You need to be extremely diligent in confirming the units. So the term 'unitless' is misleading it's very much hard set to a unit type. So no matter what you change the units of the drawing to be, the line will still extend from 0,0 to 10,10. Note there is no Unit specified вЂ“ just the numeric coordinates. The definition of a line in AutoCAD is always something like ' 0,0 вЂ“ 10,10.' In this case, the line is extending from the coordinates 0,0 to the coordinates 10,10.

If you have already begun work on a site design and are running into issues resulting from your Units and Scale settings being off, you can address the problem by verifying and correcting your units and scale. You can prevent any number of problems by ALWAYS setting your units and scale before you begin work on a drawing. Units and Scale are two of the most important settings in an AutoCAD drawing.
