In AutoCAD, symbols are used to represent various objects, features, or instructions in a drawing, such as electrical fixtures, Plumbing components, or different types of materials. They often include specific annotations that convey additional information, such as dimensions or material specifications. Symbols can be created from blocks, which are collections of objects that can be reused throughout a drawing for consistency and efficiency. Understanding these symbols is crucial for interpreting and creating technical drawings accurately.
In AutoCAD, the coordinate symbol used to denote a point's location is typically represented by the letters "X", "Y", and optionally "Z" for three-dimensional coordinates. The "X" and "Y" coordinates define the horizontal and vertical positions on a 2D plane, while "Z" denotes the elevation in a 3D space. These coordinates can be entered in various formats, such as absolute or relative values, to accurately place objects within a drawing.

The symbol used to denote "is an element of" is ( \in ). It indicates that a particular object belongs to a set. For example, if ( a ) is an element of set ( A ), it is written as ( a \in A ).
That symbol is called the radical.
Any symbol can be used to denote a set of integers. The set of all integers is denoted by Z, and the set of natural numbers by N.
