我已經在Autodesk Inventor上運行makepy，以便能夠腳本執行某些任務。我無法理解使用存儲在類字典中的屬性/方法的適當協議。我已閱讀了很多關於此的信息，包括關於_prop_map_get_的其他stackoverflow問題，但出於某種原因，不明白。這裏有一個例子：Python字典方法調用win32com
- 兩類問題，AssemblyComponentDefinition，並工分
這兩個類從makepy摘錄：
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
這是一些代碼，我試圖通過AssemblyComponentDefinition返回類型爲WorkPoints的對象類。
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')
此返回z爲AssemblyComponentDefinition的類對象。我真正想要做的是說（我知道這是想這個天真的樣子）：
newpoint = mod.AssemblyComponentDefinition.WorkPoints.AddFixed(oPoint)
我得到AssemblyComponentDefinition有沒有屬性「工分」的錯誤。再次，我需要幫助瞭解如何使用_prop_map_get_部分能夠在我的文件中創建工作點，然後運行工作點方法添加固定。
