Question

我在Autodesk Inventor上运行makepy，以便能够编写某些任务的脚本。我无法理解使用存储在类字典中的属性/方法的适当协议。我已经阅读了很多关于这个的内容，包括关于_prop_map_get_的其他stackoverflow问题，但由于某种原因，不要得到它。这是一个例子：

有问题的两个类， AssemblyComponentDefinition 和 WorkPoints

这两个类摘自makepy：

class AssemblyComponentDefinition**(DispatchBaseClass):
"""Assembly Component Definition Object"""
CLSID = IID('{AA044AA1-D685-11D3-B7A0-0060B0F159EF}')
coclass_clsid = None

    _prop_map_get_ = {
    # Method 'WorkAxes' returns object of type 'WorkAxes'
    "WorkAxes": (100663817, 2, (9, 0), (), "WorkAxes", '{28DD48B5-8D70-11D4-8DDE-0010B541CAA8}'),
    # Method 'WorkPlanes' returns object of type 'WorkPlanes'
    "WorkPlanes": (100663816, 2, (9, 0), (), "WorkPlanes", '{46785C3B-7F4A-11D4-8DDB-0010B541CAA8}'),
    # Method 'WorkPoints' returns object of type 'WorkPoints'
    "WorkPoints": (100663818, 2, (9, 0), (), "WorkPoints", '{28DD48C7-8D70-11D4-8DDE-0010B541CAA8}'),   
}

class WorkPoints(DispatchBaseClass):
"""WorkPoints Collection Object"""
CLSID = IID('{28DD48C7-8D70-11D4-8DDE-0010B541CAA8}')
coclass_clsid = None

# Result is of type WorkPoint
def AddFixed**(self, Point=defaultNamedNotOptArg, Construction=False):
    """Creates a new work point at the position specified by the input point"""
    ret = self._oleobj_.InvokeTypes(83893254, LCID, 1, (9, 0), ((9, 1), (11, 49)),Point
        , Construction)
    if ret is not None:
        ret = Dispatch(ret, 'AddFixed', '{28DD48C9-8D70-11D4-8DDE-0010B541CAA8}')
    return ret

# Result is of type WorkPoint
# The method Item is actually a property, but must be used as a method to correctly pass the arguments
def Item(self, Index=defaultNamedNotOptArg):
    """Allows integer-indexed access to items in the collection"""
    ret = self._oleobj_.InvokeTypes(0, LCID, 2, (9, 0), ((12, 1),),Index
        )
    if ret is not None:
        ret = Dispatch(ret, 'Item', '{28DD48C9-8D70-11D4-8DDE-0010B541CAA8}')
    return ret

_prop_map_get_ = {
    "Application": (2130706433, 2, (9, 0), (), "Application", None),
    "Count": (2130706438, 2, (3, 0), (), "Count", None),
    # Method 'Parent' returns object of type 'ComponentDefinition'
    "Parent": (2130706434, 2, (9, 0), (), "Parent", '{5DF8601E-6B16-11D3-B794-0060B0F159EF}'),
    "Type": (2130706435, 2, (3, 0), (), "Type", None),
}
_prop_map_put_ = {
}
# Default method for this class is 'Item'
def __call__(self, Index=defaultNamedNotOptArg):
    """Allows integer-indexed access to items in the collection"""
    ret = self._oleobj_.InvokeTypes(0, LCID, 2, (9, 0), ((12, 1),),Index
        )
    if ret is not None:
        ret = Dispatch(ret, '__call__', '{28DD48C9-8D70-11D4-8DDE-0010B541CAA8}')
    return ret

def __str__(self, *args):
    return str(self.__call__(*args))
def __int__(self, *args):
    return int(self.__call__(*args))
def __iter__(self):
    "Return a Python iterator for this object"
    ob = self._oleobj_.InvokeTypes(-4,LCID,2,(13, 10),())
    return win32com.client.util.Iterator(ob, '{28DD48C9-8D70-11D4-8DDE-0010B541CAA8}')
def _NewEnum(self):
    "Create an enumerator from this object"
    return win32com.client.util.WrapEnum(self._oleobj_.InvokeTypes(-4,LCID,2,(13, 10),()),'{28DD48C9-8D70-11D4-8DDE-0010B541CAA8}')
def __getitem__(self, index):
    "Allow this class to be accessed as a collection"
    if '_enum_' not in self.__dict__:
        self.__dict__['_enum_'] = self._NewEnum()
    return self._enum_.__getitem__(index)
#This class has Count() property - allow len(ob) to provide this
def __len__(self):
    return self._ApplyTypes_(*(2130706438, 2, (3, 0), (), "Count", None))
#This class has a __len__ - this is needed so 'if object:' always returns TRUE.
def __nonzero__(self):
    return True

这是我尝试通过 AssemblyComponentDefinition 类返回的WorkPoints类型对象的一些代码。

    import win32com.client
    from win32com.client import constants
    oApp = win32com.client.Dispatch('Inventor.Application')
    oApp.Visible=True #makes Inventor Application visible
    from win32com.client import gencache
    mod = gencache.EnsureModule('{D98A091D-3A0F-4C3E-B36E-61F62068D488}', 0, 1, 0) 
    oApp=mod.Application(oApp) 
    oAssemblyDoc=oApp.Documents.Add(constants.kAssemblyDocumentObject, "", True)
    oAss = oAssemblyDoc.Activate
    oTG = oApp.TransientGeometry
    oPoint = oTG.CreatePoint(XCoord=1.2, YCoord=3.4, ZCoord=5.3) #this works
    z=mod.AssemblyComponentDefinition('WorkPoints')

这将z返回为 AssemblyComponentDefinition 的类对象。我真正想做的是说（我知道这是想到这个的天真方式）：

newpoint = mod.AssemblyComponentDefinition.WorkPoints.AddFixed(oPoint)

我收到错误 AssemblyComponentDefinition 没有属性' WorkPoints '。同样，我需要帮助了解如何使用_prop_map_get_部分在我的文件中创建工作点，然后运行 WorkPoints 方法 AddFixed 。

这是有用的：

        i=0
        for line in range(len(oPointsOnly3)):
            oPointF = oApp.TransientGeometry.CreatePoint(XCoord=(float(oPointsOnly3[i][2].strip('"')))/.032808399, YCoord=(float(oPointsOnly3[i][1].strip('"')))/.032808399, ZCoord=float((oPointsOnly3[i][3].strip('"')))/.032808399)
            oPoint = oPartDoc.ComponentDefinition.WorkPoints.AddFixed(oPointF)
            oPoint.Name=oPointsOnly4[i][0].strip('"')
            oPartDoc.Update()
            i+=1

这可以在将应用程序对象提前绑定到mod.Application和oPartDoc到mod.PartDocument之后运行。

Python字典方法调用win32com
