Hi all,
I know package Modelical has the node called “room and tag location centering”
but i did change the phase name as shown in the image like “XX_EXIST” and “XX_NEW” then the script doesn’t work. it will work when there isn’t “XX_” as prefix infront. Does anyone know where to fix in the python script?
hi @dylanpeng, you can try this;
# dynamo version - 1.3.x, 2,x,x
import clr
clr.AddReference('ProtoGeometry')
clr.AddReference('RevitAPI')
clr.AddReference('RevitServices')
clr.AddReference("RevitNodes")
import System,Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)
from Autodesk.DesignScript.Geometry import (Geometry,
Point as pt)
from Autodesk.Revit.DB import *
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument
elems = IN[0];
# make list
if not isinstance(elems,list):
elems = UnwrapElement([elem])
else:
elems = UnwrapElement(elems)
# output
res = []
# start transaction
TransactionManager.Instance.EnsureInTransaction(doc)
# loop elements
for e in elems:
# level elevation - unit millimeter
elevation = e.Level.Elevation * 304.8
# get geo-objects of the element
geoelem = e.GetGeometryObjectFromReference(Reference(e))
# get enumerator to loop geo-objects
geoobj = geoelem.GetEnumerator()
# loop geo-objector
for obj in geoobj:
# convert to dynamo type
room_geometry = obj.ToProtoType()
# get the centroid of the element
point = room_geometry.Centroid()
# create location point with level elevation
center = pt.ByCoordinates(point.X,point.Y,elevation)
# current element location
current = e.Location.Point
# point convert to revit and minus from current location
newloc = center.ToXyz() - current
# move to new location
e.Location.Move(newloc)
# transaction done
TransactionManager.Instance.TransactionTaskDone()
# output
OUT = elems
Hi Jean,
Thank you very much. It works for " XX_ " but when I start to change the prefix say AB_, it dosent work again.
I couldn’t find in your python script which part relate the prefix.
hi @dylanpeng, the underlying issue is room status. You can try this way again.
Hi Jean,
it works! fantastic! Is it possible to do the same thing for area?
seems Python script is not always working, either crash or never stop running, maybe something wrong w/ model like bad room elements.
what package to use in order to get outer boundary of area/room?
edit: never mind, i’ll use MEPover package instead
i love this ! always try to develop out of basic nodes in dynamo even tho it could be a little more complex is my goal. since i am not so good with writing python … yet. Thanks
You are trying to move the Location Point of the Room, that input needs to be the Room elements themselves.
OH MY BUDDHA ! It works ! thank you! somehow this afternoon, i tried to connect room elements there it didnt move! 
so happy ! thank you very much for your advice
Can you post the final script? It would be very helpful!
thank you!
Here you go ^^
Move room coordination point to center.dyn (25.5 KB)
Thank you!!!
I have tried with some package and found your script. You are the best.
Hi @Bjorn_Keulemans1, which package Areas.OuterBoundary node belongs to? thanks
Rhythm.
The selection Node used there is from archi-lab.
I did learn to annotate my custom node usage in the meantime.
Seems the center is not the actual center?!?
What am i missing? @Qnguyen2688
Revit 2020.2
Any idea why? @jean
hi @bvs1982 , frankly speaking, i have no idea. Better consult with ADSK team …
