Click the Primary Units tab and you will see the following:

As an introduction to the Primary units, let us assume that your client wants the dimension in decimal format, and one other sub-contractor wants it in Architectural format. The solution for that would be to show two numbers for each dimension; the first will be the Primary Units and the second will be the Alternate Units. In this tab we will cover the Primary Units.

Under Linear dimensions adjust the following settings:

• Choose the Unit format, selecting one of six formats.

• Specify the Round off number. If you select, for instance 0.5, then AutoCAD will round off any dimension to the nearest 0.5.

Input the Prefix and/or the Suffix to illustrate this part. Take a look at the following illustration:

Under Measurement scale adjust the following:

• Input the Scale factor. To explain the importance of this setting, let's take look at an example: Assume we have a drawing that uses the millimeter as unit; hence, a length of 10 m will be 10,000. But in the dimension we want the value 10 to appear, and...
