In AutoCAD, the origin is the point where the X-axis and Y-axis intersect. By default, this point is located at the intersection of the grid lines that are at coordinates 0,0 on the X- and Y-axes.
You can see the location of the origin in the drawing area by looking for the intersection of the grid lines. You can also verify the location of the origin by entering the “ID” command on the command line and clicking on the point where the X- and Y-axes intersect. This will display the coordinates of the point, which should be 0,0.
If you want to change the location of the origin, you can do so by using the “MOVETO” command. This command allows you to specify a new point for the origin and move all the objects in the drawing relative to this new point.
I hope this helps! Let me know if you have any other questions.
