Create wall by profile Python

[arantza]

Hi,

I’m trying to create a wall by a list of lines. I’ve used a code from another Topic of 2019 but it is not working. I get an error saying that I have a string. Could anyone help me? Thanks in advance.

You can see below the code, inputs and error

Hi,

• check your input curves, it is possible that your curves are not correctly aligned on the same plane

• the curves are far from the internal origin? It creates accuracy issues

Hi,

Thanks for your comment, but the lines are aligned on the same plane. I have corrected the code and now I have a new error… I attach the images

Remove these nodes

What is the unit of your project ?meter, millimeter ?

Hello,
if it can help
assuming it’s mm

I left only the creation of the wall in the transaction
python script:

import clr
import System

from System.Collections.Generic import *
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager 
from RevitServices.Transactions import TransactionManager 

clr.AddReference("RevitAPI")
clr.AddReference("RevitAPIUI")

import Autodesk 
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *

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

curves=IN[0]
level=UnwrapElement(IN[1])
type=UnwrapElement(IN[2])

typeid=type.Id
levelid=level.Id
profile=List[Curve]()

for curve in curves:
    profile.Add(curve.ToRevitType())

TransactionManager.Instance.EnsureInTransaction(doc)

wall=Wall.Create(doc,profile,typeid,levelid,False)

TransactionManager.Instance.TransactionTaskDone()


OUT = wall

edit: you have forgotten import System

Hi Christian, thanks for your help, but I still have warnings. I have copied your code and I get this

Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed.
Traceback (most recent call last):
File “”, line 42, in
Exception: Failed to create the wall.

Line 42 is were the wall is created:
wall=Wall.Create(doc,profile,typeid,levelid,False)

Hi Christian,

Many thanks! With your script I don’t have the warning. I’ll review mine, I have something wrong for sure.

The problem now is that it doesn’t model the geometry of the points correctly. It seems that is attached to the levels. I don’t know why Revit modify the geometry.

Have you modified your levels’ values to create correcly the geometry?

Thanks again

Hello, no special handling in addition, I started from a standard architectural template.

Ok, thanks for your help. This might be happening because I’m using Revit 2021. I’ll keep trying
