Before you start to draw, you set the format and the number of decimal places to be used when you enter and display linear units.
You can choose from several common conventions to represent the display style and the precision of distances and coordinates. Depending on what you specify, you can enter and display in decimal format, fractional format, or other notation. These settings affect
You can set the unit type and precision in the Drawing Units dialog box, the Quick Setup wizard, or the Advanced Setup wizard.
When you specify the display precision of units, the values for coordinates and distances are rounded off. However, the internal precision of coordinates and distances is always maintained regardless of the display precision.
For example, if you set the display precision of decimal-format units to 1 (or 0.0), the display of coordinates is rounded to one place after the decimal point. Thus, the coordinates 0.000,1.375 are displayed as 0.0,1.4, but the internal precision is still maintained.
In architectural format, to enter feet and inches, indicate feet using the prime symbol ('), for example, 72'3. You don't need to enter quotation marks (â€œ) to specify inches.
