Question

我是这个网站的新手，并且还是编程的新手。我一直在Maya2018中使用Python作为我的语言（Pycharm作为我的脚本编辑器）来开发程序生成器。

我收到这样的错误消息：“错误：未定义全局名称'WidthSections'。”
获取“窗口”模型的宽度和高度时遇到问题。我可能以错误的方式进行了处理，但是我尝试将xmax减去xmin来获得宽度，并将ymax减去ymin来获取高度。也许我没有写正确的地方。任何建议都会很有帮助！

代码：

恰如错误消息所述，您有一个变量widthSection，该变量在未定义的行while i <= widthSections:上使用。在代码中的某些时候，需要给该变量一个不会发生的值。同样，您可能会发现出于相同原因而未定义depthSections

您有两个未使用的变量numWindowsInwidth和numWindowsInDepth。我猜想这些是您实际上应该在该循环中使用的变量，而不是您当前使用的widthSections和depthSections。

例如

while i <= numWindowsInwidth:
    sectionWidth = cmds.getAttr(bWindow, xmax-xmin)
    cmds.duplicate()
    cmds.move(-sectionWidth, 0, 0, relative=True)
    i += 1
