Hello all,

I want to create a solid from a revit profile (it is just a rectangle). Every time that I run the script after the node ‘BoundingBox.ToCuboid’ Dynamo crashes.  
The python script that I use in order to get the curves from the revit profile is the following :

import clr  
clr.AddReference(‘ProtoGeometry’)  
from Autodesk.DesignScript.Geometry import \*

# Import ToDSType(bool) extension method

clr.AddReference(“RevitNodes”)  
import Revit  
clr.ImportExtensions(Revit.Elements)

# Import DocumentManager and TransactionManager

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

from System.Collections.Generic import \*

# Import RevitAPI

clr.AddReference(“RevitAPI”)  
import Autodesk  
from Autodesk.Revit.DB import \*

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

type = UnwrapElement(IN[0].Family.Name)  
name = UnwrapElement(IN[0].Name)

family = UnwrapElement(IN[0]).Family

TransactionManager.Instance.ForceCloseTransaction()  
famDoc = doc.EditFamily(family)

famCollector = FilteredElementCollector(famDoc)  
sketch = famCollector.OfClass(Sketch)

for i in sketch:  
cArray = list(i.Profile)  
cArray[:] = [[Revit.GeometryConversion.RevitToProtoCurve.ToProtoType(y, True ) for y in x] for x in cArray]  
OUT = cArray

Any idea?

Thank you!

My guess is that this is an issue with the geometry engine having a hard time making or displaying a cuboid with no height. Try pulling the minimum and maximum point instead, and use the XY values to build a rectangle which you can patch.
