FROM command

Allows you to enter relative coordinates with respect to a reference point whenever a command prompts you to enter a point.

Icon:

Note: From is a command modifier, not a command, and so it is entered only during a drawing or editing command.
Note: This command is useful for starting entities offset from another entity, such as inserting a door relative to the end of a wall.

Options within the command

Base point
Pick a point or enter coordinates to specify the base point.
Offset or regular point
Enter the offset by specifying relative coordinates, using the @x,y,z format
