使用RevitPythonShell在活动视图中覆盖图形设置

Question

我正在尝试使用RevitPythonshell覆盖Revit中3D视图中的墙的图形。我设法使用Python节点在Dynamo中完成这项工作。

到目前为止，我有以下代码;

import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager 

from System.Collections.Generic import List


doc = DocumentManager.Instance.CurrentDBDocument

TransactionManager.Instance.EnsureInTransaction(doc)

walls = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Walls)
elements = walls.OfCategory(BuiltInCategory.OST_Walls).WhereElementIsNotElementType()


color = Autodesk.Revit.DB.Color(255,50,50)
ogs = OverrideGraphicSettings().SetProjectionFillColor(color)


for i in elements:
    doc.ActiveView.SetElementOverrides((i.Id), ogs)


TransactionManager.Instance.TransactionTaskDone()

当我在RevitPythonShell中运行它时，它什么也没做。我没有任何错误或任何错误。当我打印doc.ActiveView.SetElementOverrides((i.Id), ogs)时，它返回None。

我在这里缺少什么？我在Revit中的3D视图中是活动视图。我正在开始并结束交易。

Here与Dynamo节点中的Python节点中的代码有些相同。

Answer 1

通过一些调整，您的代码可以正常运行：

import clr

clr.AddReference('RevitAPI') 
clr.AddReference('RevitAPIUI') 
from Autodesk.Revit.DB import * 
from Autodesk.Revit.UI import *

app = __revit__.Application
doc = __revit__.ActiveUIDocument.Document

elements = list(FilteredElementCollector(doc, doc.ActiveView.Id))

color = Color(255,50,50)
ogs = OverrideGraphicSettings().SetProjectionFillColor(color)

t = Transaction(doc, 'Color Walls')
t.Start()
try:
    for i in elements:
        if i.Category.Name == 'Walls':
            doc.ActiveView.SetElementOverrides((i.Id), ogs)
            print 'element overridden'
except Exception as e:
    print '- Failed to override -'
    print '- ' + str(e) + ' -'
t.Commit()

• 当您将View.Id传递给FilteredElementCollector时，您会收集 在该视图中可见的一切
• 在Dynamo的RevitPythonShell中，事务的工作方式略有不同，你可以在实际修改数据库的代码周围打开它们。
• 当你进入交易时，将代码包装在try / except块中是值得的，因为即使有错误你也需要完成交易

我设法以下列方式为不同类型的墙壁着色。

import clr 
clr.AddReference('RevitAPI') 
clr.AddReference('RevitAPIUI') 
import Autodesk
from Autodesk.Revit.DB import * 
from Autodesk.Revit.UI import *

from random import randint

app = __revit__.Application
doc = __revit__.ActiveUIDocument.Document

#elements = list(FilteredElementCollector(doc, doc.ActiveView.Id))
wall_collector = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Walls)
wall_instances = wall_collector.OfCategory(BuiltInCategory.OST_Walls).WhereElementIsNotElementType()



fill_patterns = FilteredElementCollector(doc).OfClass(FillPatternElement).WhereElementIsNotElementType().ToElements()

for i in fill_patterns:
    if i.Name == 'Solid fill':
        solid_fill = i.Id

element_list = []
element_name_list = []

for i in wall_instances:
    element_name_list.append(i.Name)
    element_list.append(i.Id)

wall_color_dict = {}
for i in set(element_name_list):
    wall_color_dict[i] = Color(randint(0,250), randint(0,250), randint(0,250))

t = Transaction(doc, 'Color Walls')

t.Start()

for i in wall_instances:
    for k, v in wall_color_dict.iteritems():
        if k == i.Name: 
            a=OverrideGraphicSettings().SetProjectionFillPatternId(solid_fill)
            b=OverrideGraphicSettings(a).SetProjectionFillColor(v)
            p = doc.ActiveView.SetElementOverrides(i.Id, a)
            c = doc.ActiveView.SetElementOverrides(i.Id, b)




t.Commit()
