The Dynamic UCS Command is a useful tool for drawing in AutoCAD. It allows you to draw a viewport without having to worry about the coordinate system.
- Open the UCS Manager by pressing Ctrl+U or right-clicking on the UCS icon in the status bar and choosing “UCS Manager” from the menu that appears.
- In the UCS Manager, select Dynamic UCS from the list of options on the left-hand side of the window and click OK.
- In your drawing, press F5 to activate Dynamic UCS mode and then start drawing by clicking on a point in your drawing and dragging with your mouse until you reach your desired size.
