AutoCAD Commands: Line, Circle, Rectangle, Trim, Extend

AutoCAD is a powerful computer-aided design (CAD) software that is widely used for creating and editing 2D and 3D designs. The software provides a vast array of commands to create and modify different types of geometric entities. In this article, we will focus on the commands related to lines, circles, rectangles, trim, and extend.

Line

The line command is used to create a straight line in AutoCAD. To create a line, follow these steps:

1. Press the 'L' key on the keyboard or click on the 'Line' tool in the 'Draw' toolbar.
2. Pick the starting point of the line.
3. Pick the endpoint of the line.

You have successfully created a line between the two points.

Circle

The circle command is used to create a circle in AutoCAD. To draw a circle, follow these steps:

1. Press the 'C' key on the keyboard or click on the 'Circle' tool in the 'Draw' toolbar.
2. Pick the center point of the circle.
3. Pick the endpoint of the circle's diameter.
4. Pick another endpoint of the circle's diameter.

You have successfully created a circle with the specified center and diameter.

Rectangle

The rectangle command is used to create a rectangle in AutoCAD. To create a rectangle, follow these steps:

1. Press the 'R' key on the keyboard or click on the 'Rectangle' tool in the 'Draw' toolbar.
2. Pick the starting point of the rectangle.
3. Pick the endpoint of the rectangle's diagonal.

You have successfully created a rectangle with the specified starting point and diagonal end point.

Trim

The trim command is used to trim a line, polyline, or circle to another line, polyline, or circle. To use the trim command, follow these steps:

1. Press the 'T' key on the keyboard or click on the 'Trim' tool in the 'Modify' toolbar.
2. Select the boundary object that you want to trim the object against.
3. Select the object that you want to trim.

The object will be trimmed to fit within the boundary object.

Extend

The extend command is used to extend a line, polyline, or circle beyond another line, polyline, or circle. To use the extend command, follow these steps:

1. Press the 'E' key on the keyboard or click on the 'Extend' tool in the 'Modify' toolbar.
2. Select the object that you want to extend.
3. Select the boundary object that you want to extend the object beyond.

The object will be extended to fit beyond the boundary object.

In conclusion, AutoCAD provides a comprehensive set of commands for creating and modifying various types of geometric entities. The line, circle, rectangle, trim, and extend commands are essential tools for creating precise and accurate designs. Understanding these commands and their usage will greatly enhance your ability to work with AutoCAD.
