Wrap Autodesk.DB.Solid to get a solid in Dynamo

Hi, all!

I am trying to get Rooms’ geometry through the API. I am currently getting the geometry successfully as Revit API elements:

Here’s the code:

import clr
import sys
sys.path.append('C:\Program Files (x86)\IronPython 2.7\Lib')

import System
from System import Array
from System.Collections.Generic import *

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

clr.AddReference("RevitNodes")

import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)

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

clr.AddReference("RevitAPI")
clr.AddReference("RevitAPIUI")

import Autodesk 
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *

doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication 
app = uiapp.Application 
uidoc = uiapp.ActiveUIDocument

rooms = UnwrapElement(IN[0])

outlist = []

for room in rooms:
	outlist.append(room.Geometry)
	outlist.append(room.ClosedShell)

OUT = outlist

However, once I try to wrap them, I get the following warning:

It works neither with ToDSType, nor with ToProtoType methods:

Normally, ToProtoType() should work when revit geometry is concerned, at least according to this: Python 0.6.3 to 0.7.x Migration · DynamoDS/Dynamo Wiki · GitHub

Please help :pray:

I found the solution:

import clr
import sys
sys.path.append('C:\Program Files (x86)\IronPython 2.7\Lib')

import System
from System import Array
from System.Collections.Generic import *

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

clr.AddReference("RevitNodes")

import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)

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

clr.AddReference("RevitAPI")
clr.AddReference("RevitAPIUI")

import Autodesk 
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *

doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication 
app = uiapp.Application 
uidoc = uiapp.ActiveUIDocument

rooms = UnwrapElement(IN[0])
outlist = []

options = SpatialElementBoundaryOptions()
options.SpatialElementBoundaryLocation = SpatialElementBoundaryLocation.Finish
calculator = SpatialElementGeometryCalculator(doc)

for room in rooms:
	solid = calculator.CalculateSpatialElementGeometry(room).GetGeometry()
	outlist.append(solid.ToProtoType())

OUT = outlist

Seems like my method of obtaining the solid was wrong :slight_smile:

It also works fine if you append the individual faces:

import clr
import sys
sys.path.append('C:\Program Files (x86)\IronPython 2.7\Lib')

import System
from System import Array
from System.Collections.Generic import *

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

clr.AddReference("RevitNodes")

import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)

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

clr.AddReference("RevitAPI")
clr.AddReference("RevitAPIUI")

import Autodesk 
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *

doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication 
app = uiapp.Application 
uidoc = uiapp.ActiveUIDocument

rooms = UnwrapElement(IN[0])
outlist = []

options = SpatialElementBoundaryOptions()
options.SpatialElementBoundaryLocation = SpatialElementBoundaryLocation.Finish
calculator = SpatialElementGeometryCalculator(doc)

for room in rooms:
	solid = calculator.CalculateSpatialElementGeometry(room).GetGeometry()
	
	for face in solid.Faces:
		outlist.append(face.ToProtoType())

OUT = outlist

Hope someone finds this usefull
