How to make a roof fascia

Developers

Hello

I am trying to make a roof fascia

i don’t know how to make a reference array
This is a part of the code

RoofExtrusionLines   are lines wich i used to create a roof  (roof by extrusion)

refArrays = []

outList = []

for lines in RoofExtrusionLines:
	rArr = ReferenceArray()
	for l in lines:
		rArr.Append(Reference(l))
	refArrays.append(rArr)
	
TransactionManager.Instance.EnsureInTransaction(doc)
FasciaNew = doc.Create.NewFascia(Fascia, refArrays)   
TransactionManager.Instance.TransactionTaskDone()

OUT = Fascia

I don’t see anything wrong with the code above. Are you importing everything from the Revit API to allow you to use the ReferenceArray constructor directly? e.g.

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

ref_array = ReferenceArray()

Hello cgartland

I solved the problem

index = [3,4,7,8]

fascias = []
opt = Options()
opt.ComputeReferences = True
roofSolid = footprintRoof.get_Geometry(opt)

edgeRefs = []
temp = []

for i in roofSolid:
	edges = i.Edges
	for j in edges:
		edgeRefs.append(j.Reference)

ref3 = edgeRefs[3]
for i in index:
	ref = edgeRefs[i]
	TransactionManager.Instance.EnsureInTransaction(doc)
	FasciaNew = doc.Create.NewFascia(Fascia, ref)   
	TransactionManager.Instance.TransactionTaskDone()
	fascias.append(FasciaNew.ToDSType(False))

OUT = fascias
