i、 e.X，Y，Z为浮点数。特定应用程序“FreeCAD”使用Python作为基本脚本语言（宏）原生FreeCAD对象的原生方法是

Vector

，即

FreeCAD.Vector

向量是（X，Y，Z），即

FreeCAD.vector（105453.16406290917.86718751274.77026367）

作为进一步的详细示例：

您需要什么帮助还不完全清楚，但这可能会给您一些想法，帮助您解决问题：

>>> def vector(x, y, z):
...     print("vector: x=%f, y=%f, z=%f" % (x, y, z))
... 
>>> vector(1, 2, 3)
vector: x=1.000000, y=2.000000, z=3.000000
>>> v = [1, 2, 3]
>>> vector(*v)
vector: x=1.000000, y=2.000000, z=3.000000

请查看我们的帮助中心。特别是如何创建。您提供的信息太多，因此您的问题相当不清楚。在

s=s.replace（'，'，'FreeCAD.Vector'）

之后，打印的结果应该是

（0.0034596999FreeCAD.Vector 0.0034775001FreeCAD.Vector 0.0010091923）

，而不是问题结尾处当前显示的内容。请回答您的问题并创建一个最小的示例，说明您遇到的问题（并且正确执行）。看起来FreeCAD可以直接从CSV导入。为什么您需要编写代码来执行此操作？或者这不创建FreeCAD矢量？
