It will not stop prompting until pressing ENTER. **Undo:**Remove the last drawn straight line and redraw from the last point. **Close:** Draw a line to close the 3D polyline from the end point to the start point and exit the command. To close 3D polyline, there must be at least two line segments. ## Other versions with matching text [GstarCAD 2019](Help%20System/GSTARCAD/2019/Commands/3D/3DPOLY%20Command.md) · [GstarCAD 2020](Help%20System/GSTARCAD/2020/Commands/3D/3DPOLY%20Command.md) · [GstarCAD 2021](Help%20System/GSTARCAD/2021/Commands/3D/3DPOLY%20Command.md)
