In AutoCAD, the Unite command is used to join the objects end to end to form a single entity. Depending on the requirements, the objects might be curved or straight. It creates a single 2D or 3D object by combining a succession of linear and curved objects.

In AutoCAD, the Unite command is used to join the objects end to end to form a single entity. Depending on the requirements, the objects might be curved or straight. It creates a single 2D or 3D object by combining a succession of linear and curved objects.

As seen in the image below, the erase command is used to remove or eliminate things from the drawing: The numbers 1 and 2 refer to the selected objects. The 'Delete' key on the keyboard can also be used to delete the selected objects.

The undo function can be used to undo a mistake, such as erasing the incorrect word from a phrase. Any actions that were previously undone using the undo function are restored using the redo function. For example, if you entered a word and then used the undo function to delete it, the redo function restores the deleted word ("undid").

One of the most common functions in AutoCAD is the break command, which is used to separate objects that are connected to each other. The break command can be used to create a new line and make it independent from the original line.
