Hi,
I just want to extract line from zone. BoundingBox for zone do not exist in Dynamo. And a want the real perimeter of a non rectangle space.
In Revit lookup i can see BoundingBox and Geometry.
Is it possible in Python to have those information ?
It’s more difficult to extract global perimeter of very different form spaces.

I find this in a topic
But a prefer extract Geometry, (BoundingBox are not correct)

This should be what you need.
Hi,
Is’t ok for Zone HVAC but not for Zone-System
Daniel OLIVÈS
Can you try to better explain exactly what you’re after? Any relevant images would be helpful as well.
Hi Nick,
Here some png to explain differences.
With Zone HVAC lines are spaces lines and not only the peripherical line of the zone
z.Boundary give directely lines
With System Zone line are draw manually and they are in peripherical of the zone
line are in 3rd level Geometry, GeometryElement and lines
And the last, is what i try to do : 3 periphery lines for 3 SSi zones (Fire plan)
If i do that with region in color it need 3 plans, with only peripherical line with some offset
i draw only one plan.

Have you tried getting this info with Python? RevitLookup is wonderful for learning and applying the Revit API since it shows you exactly what the methods and properties look like and how everything is connected.
Hi,
I try to do that but with System-Zone i don’t find a solution to get line
Daniel OLIVÈS
PJ: Fire plan sample
You haven’t shown what you’ve tried though. How are you trying to get the boundary lines?
Is this what you’re expecting?

@daniel82KGE I guess what you are looking for is a Generic Zone element boundary (GetBoundaries() Method):

Hi Tradeli,
I get this error :
Avertissement:IronPythonEvaluator.EvaluateIronPythonScript l’opération a échoué.
Traceback (most recent call last):

@daniel82KGE your input is one zone or a list of zones?
Hi,
My answer was not correct
My problem was i have use select all elements of category and not select model
I have a list of list if the script is correct
Thank’s for your help

Hi,Tradelie
If i run the script a second time list is empty ?

@daniel82KGE try to close Dynamo then re-run the script/ Use Dynamo Player/ Use Transaction.End
Hi tradelie,
When i close only Dynamo, same thing, when i close Revit and Dynamo
on 3 GenericZone only 1 have Line ??
I add before out
TransactionManager.Instance.TransactionTaskDone()
Daniel OLIVÈS
@daniel82KGE can you share a Revit sample file?
