Hello Problem Solvers, I am jus wondering is that possible to mirror a door using dynamo as we do in Revit.
In my case I don’t have flip controls and I have removed it. I have to do this for 20 different door types.
So any help would be appreciated! Thanks in Advance.
Hey,
Perhaps try this?
Hope that helps,
Mark
Hello, dont think "flip hand orientation will work, without flips…without trying 
Thanks for your time, @Mark.Ackerley. As @sovitek mentioned it works only with flip arrows placed in the family.
This is a handy place to start: MirrorElements Method (Document, ICollection(ElementId), Plane, Boolean)
Thanks for the link @jacob.small. I can understand what Revit actually needs but I jus wondering how to write a python script based on the link. I tried few from Bakery package but I get a error “Can’t Mirror the element away from host”!.
That is a valid error… come to think of it I don’t know that this would be any bit of a good idea… might actually make more sense to add the flip state to the family (I think that might be automatable as well).
Edit: confirmed as a possibility - NewControl Method
Remember that change would need to be made once per family, so if you have 20 types of one family it is a single manual edit, but if you have twenty families with one type… automate it.
Hi,
This should flip it, even if there is no flip ticked, just feed a door / list of doors…
import clr
# 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
# Import RevitAPI
clr.AddReference("RevitAPI")
import Autodesk
from Autodesk.Revit.DB import *
doc = DocumentManager.Instance.CurrentDBDocument
if isinstance(IN[0],list):
doors = UnwrapElement(IN[0])
else:
doors = [UnwrapElement(IN[0])]
TransactionManager.Instance.EnsureInTransaction(doc)
for door in doors:
door.flipHand()
TransactionManager.Instance.TransactionTaskDone()
OUT = door.HandFlipped
Hope that helps,
Mark
Hi Mark,
Once again Thank you for your valuable time, It didn’t work in my door family, I removed the flip arrow from elevation as well. Do I need to make some changes in door family or in the script?
Can you post one of the door families for people to test with @gokul.saravanan? Also, what Revit year are you in?
Hello
a solution with Python (without flip controls)
import clr
import sys
import System
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
import Autodesk.DesignScript.Geometry as DS
#import Revit API
clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *
import Autodesk.Revit.DB as DB
#import transactionManager and DocumentManager (RevitServices is specific to Dynamo)
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument
toList = lambda x : x if hasattr(x, '__iter__') else [x]
flipdoors = []
#Preparing input from dynamo to revit
doors = toList(UnwrapElement(IN[0]))
TransactionManager.Instance.EnsureInTransaction(doc)
for door in doors:
locPt = door.Location.Point
wall = door.Host
hostLine = wall.Location.Curve
normAxe = hostLine.Direction.Normalize()
tf = Transform.CreateTranslation(normAxe)
newPt = tf.OfPoint(locPt)
plane = Plane.CreateByNormalAndOrigin(normAxe, newPt)
doorId = door.Id
DB.ElementTransformUtils.MirrorElement(doc, doorId, plane)
doc.Delete(doorId)
doc.Regenerate()
# get all the doors in model
newdoors = list(FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Doors).WhereElementIsNotElementType().ToElements())
# get the last by Id value
newdoors.sort(key = lambda x : x.Id.IntegerValue)
lastDoor = newdoors[-1]
# fix location
lastDoor.Location.Point = locPt
flipdoors.append(lastDoor)
TransactionManager.Instance.TransactionTaskDone()
OUT = flipdoorsI don’t know, need to try, it seems a little more complicated because the element mirroring has to be achieved with an offset for the door to cut the wall
Thanks for sharing this tutorial! 
Hi @Mark.Ackerley @sovitek @jacob.small , I like to thank you guys for your valuable time for spending on my topic to find a solution.
Hello! It doesn’t work for Revit 2022 
. It works for one door from the list and others remove
