Hello, free modeling can be operated by pressing Ctrl + left mouse button to frame select (can also be combined), and then click on the Move button at the top of the interface. (Accurate movement parameters can be entered at the bottom left corner)

To copy the free modeling shape, you can click on the well-combined model, or press Ctrl + left mouse button to frame select. After clicking Move, press the Shift key. A "+" icon appears next to the mouse, indicating that copying and moving can be performed.
