唯一的建议是将戒指圈的需要配对目标曲面，在原位复制一份（Selected edit→copy→paste）将戒指圈隐藏起来，再进行定位之类的操作，这可以有效避免捕捉不准确带来的问题。
（The only suggestion is to match the target surface of the ring ring ring, make a copy in situ (Selected edit → copy → paste), then hide the ring ring, and perform positioning and other operations, which can effectively avoid problems caused by inaccurate capture.）
