使用python在revit中创建和分配子类别

Lue*_*erJ 5 python revit revit-api revitpythonshell

对于熟悉Revit API和python的一些人,我有一个问题:

我一直在使用dynamo中的spring nodes包来创建一个相当大的自由对象系列,每个对象都在它们自己的系列中.FamilyInstance.ByGeometry的工作方式,它采用实体列表,并使用模板系列文件为每个实体创建一个族实例.结果非常好.(可以在这里找到spring节点:https://github.com/dimven/SpringNodes)

但是,缺点是现在我有大约200个单独的实例,所以对每个实例进行更改是相当痛苦的.我一开始认为可以使用dynamo来创建一个新的子类别,并将每个族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(我正在工作的项目和该系列的每个实例).这让我想看看我是否可以使用python来做到这一点.

我在rhino中使用了python并且相处得很好,但我仍在学习Revit API.但基本上我的想法是:1.在Revit项目环境中选择一系列族实例2.遍历每个实例3.将其保存到指定位置4.在每个族实例中创建一个新的子类别(子类别将是对于所有选定的族实例都相同)5.在实例中选择每个实体中的实体6.将实体设置为此新创建的子类别7.关闭族实例并保存

我的问题是,这听起来像是根据您对Revit API的了解可以实现的吗？

非常感谢您的时间和建议.

更新:

我在revit api中找到了一个描述我要做的事情的部分:http://help.autodesk.com/view/RVT/2015/ENU/？guid = GUID-FBF9B994-ADCB-4679-B50B -2E9A1E09AA48

我已经第一次将它插入到dynamo节点的python代码中.其余的代码工作正常,除了我添加的新部分(见下文).请原谅变量,我只是保持我正在黑客攻击的代码原作者的逻辑:

(注意:变量进来是在数组中)

#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

正如我在每封电子邮件中回答您最初的询问一样，您的目标在 Revit API 中对我来说听起来完全可行。恭喜您已经取得了如此大的成就。查看上面引用的 Revit API 帮助文件和开发人员指南的链接，似乎在定义族时必须在族文档中执行代码。您尝试执行它的上下文尚不清楚。您是否使用过EditFamily打开族定义文档？您在什么上下文中执行？
