使用python在revit中创建和分配子类别
使用python在revit中创建和分配子类别
提问于 2015-12-13 21:54:32
对于熟悉Revit和python的一些人，我有一个问题：
我一直在使用dynamo中的spring节点包来创建一个相当大的自由形式对象系列，每个对象都在他们自己的家庭中。按照FamilyInstance.ByGeometry的工作方式，它接受一个固体列表，并使用一个模板族文件为每个人创建一个系列实例。结果相当好。(在这里可以找到spring节点：https://github.com/dimven/SpringNodes)
然而，缺点是，现在我有大约200个单独的实例，因此对每个实例进行更改都是相当痛苦的。起初，我认为可以使用dynamo创建一个新的子类别，并将每个家庭实例中的实体设置为这个新的子类别。不幸的是，我意识到这是不可能的，因为dynamo不能同时在两个不同的Revit环境中打开(我正在工作的项目以及家庭的每个实例)。这让我想看看我是否可以使用python来完成这个任务。
我已经在犀牛中使用了python，并且可以很好地相处，但是我仍然在学习Revit。但基本上，我的想法是: 1.在Revit项目环境中选择一系列家庭实例；2.遍历每个实例；3.将其保存到指定的位置；4.在每个家族实例中创建一个新的子类别(对于所有选定的家庭实例，子类别相同)。5.在实例6中选择实存。将实体设置为新创建的子类别7。关闭家庭实例并保存
我的问题是，根据您对Revit的了解，这听起来像是可以实现的吗？
非常感谢您的时间和建议。
更新：
我在revit中找到了一个部分，它描述了我想要做的事情：http://help.autodesk.com/view/RVT/2015/ENU/?guid=GUID-FBF9B994-ADCB-4679-B50B-2E9A1E09AA48
我第一次尝试将它插入到dynamo节点的python代码中。除了新的im部分之外，其余代码都能正常工作(请参阅下面的代码)。请原谅这些变量，我只是遵循了我正在破解的代码的原始作者的逻辑：
(注意:输入的变量在数组中)
#set subcategory
try:
#create new sucategory
fam_subcat = famdoc.Settings.Categories.NewSubcategory(fam_cat, get_Item(subcat1.Name))
#assign the mataterial(fam_mat.Id) to the subcategory
fam_subcat.Material = famdoc.GetElement(fam_mat.Id)
#assign the subcategory to the element (s2)
s2.Subcategory = fam_subcat
except: pass任何关于这部分代码的帮助或建议都将不胜感激。
更新:有关章节的上下文，请参阅下面的完整代码：

#assign the mataterial(fam_mat.Id) to the subcategory

正如我在您最初的每封电子邮件查询中回答的那样，在Revit中，您所针对的目标听起来完全可行。恭喜你已经走得这么远了。查看上面引用的Revit帮助文件和开发人员指南的链接，似乎必须在定义家族时在家族文档中执行代码。您正在尝试执行它的上下文并不清楚。您是否使用EditFamily打开家庭定义文档？您在执行什么上下文？
