What is geometric tolerance in AutoCAD?
AutoCAD allows you to add GD&T symbols to drawings using the TOLERANCE command. Accessing the TOLERANCE command displays the Geometric Tolerance dialog box. This is the primary method for adding feature control frames, geometric tolerancing symbols, and datum feature symbols.

What are the 3 types of tolerances?
These are grouped into form tolerance, orientation tolerance, location tolerance, and run-out tolerance, which can be used to indicate all shapes.
