Revit API/Dynamo 脚本中的 MullionType 错误
MullionType errors in Revit API/Dynamo script
我正在编写一个 Python 脚本，该脚本接受一组输入线并将竖框分配给它们相交的相应网格线。但是，我收到一个奇怪的错误：
我不知道如何在脚本结尾处更正。 Python 告诉我它需要一个 MullionType 并得到一个 Family Type（见图）。我使用的是 Spring 节点的 Collector.WallTypes 的修改版本，它收集竖梃类型，但节点的输出是脚本不接受的族类型。知道如何让 Mullion Type 进入最终的 Python 节点吗？

对于代码的混乱表示歉意，这是对我一直在处理的另一个节点的修改。感谢您的帮助。
博,
您的问题根源在于 Dynamo 如何包装元素以用于其自己的模型。最后一个电话 .ToDSType(True) 是问题的要点。 MullionType class 是 Revit 中 ElementType class 的子class（它继承属性）。当 Dynamo 团队将该对象包装到自定义包装器中时，他们只编写了一个对所有 ElementType 都一视同仁的顶级包装器，因此这会输出一个 ElementType/FamilyType 而不是特定的 MullionType。
首先，我建议您替换代码中的代码行：
mullionType = IN[3]
与：
mullionType = UnwrapElement(IN[3])
这是他们用于展开元素的内置方法，用于调用 Revit API。
如果这仍然是一个问题，您可以尝试再次检索 MullionType 对象，这次是直接在您的脚本中，然后再使用它。您可以这样做：
for x,y,z in zip(keyGridLines,keySegments,isPrimary):
projectedGridlines1 = []
for h,j,k in zip(x,y,z):
for i in j:
if i != None:
h.AddMullions(i,doc.GetElement(mullionType.Id),k)
projectedGridlines1.append(h)
projectedGridlines.append(projectedGridlines1)
这应该确保您在包装之前获得 MullionType 元素。
同样，先尝试解包，如果首先不起作用，则调用 GetElement()。
