Changing Units in AutoCAD: A Step-by-Step Guide
Understanding Default Units in AutoCAD
AutoCAD predominantly uses inches as its default measurement unit. This means that when you enter a dimension, the software interprets it in inches. For instance, typing “6” is recognized as 6 inches, while the symbol “’” denotes feet. Notably, AutoCAD automatically converts 12 inches into 1 foot, providing flexibility in measurements.

Using the Zoom Command Effectively
The zoom functionality in AutoCAD allows you to manipulate the view of your drawing efficiently. Here’s how to use it:
-
Window Zoom: Draw a rectangle around the area you want to focus on. AutoCAD will zoom into this section, filling the entire window.
