Transfer walltypes to project python

[ckepner]

I'm having trouble creating a python version of https://thebuildingcoder.typepad.com/blog/2015/05/transferring-a-wall-type.html

I want to collect all the walltypes of a project and transfer them into the new open model.

Issue is happening when I try to duplicate the walltype into the new model.

import clr
clr.AddReference("RevitNodes")
import Revit
clr.AddReference('RevitAPIUI')
clr.AddReference("System.Drawing")
clr.AddReference("System.Windows.Forms")
clr.AddReference("RevitAPI")
import Autodesk
import System.Drawing
import System.Windows.Forms
from Autodesk.Revit.DB import *
from System.Drawing import *
from System.Windows.Forms import *
import System
from System.Collections.Generic import *

app = __revit__.Application
doc = __revit__.ActiveUIDocument.Document


class SelectionForm(Form):
    def __init__(self, SelNames):
        self.revname = SelNames
     
        self.Text = 'Transfer Elements'
        self.label = System.Windows.Forms.Label()
        self.label.Text = "Select Element Type"
        self.label.Location = Point(1, 50)
        self.label.Height = 30
        self.label.Width = 200
        self.count = 0
	
	
        self.cb = System.Windows.Forms.ComboBox()
        self.cb.Width = 200
        self.cb.Height = 20
        self.cb.Location = Point(15,20)
        self.cb.DataSource = self.revname
    
        self.button = System.Windows.Forms.Button()
        self.button.Text = 'Element Type'
        self.button.Location = Point(15,60)
        self.button.Width = self.cb.Width
        self.button.Height = 25
        self.button.Click += self.button_click

        self.Width = self.cb.Width + 50
        self.Height = 150
	
        self.Controls.Add(self.cb)
        self.Controls.Add(self.button)

    def button_click(self, sender, event):
        self.selected = self.cb.SelectedValue
        self.Close()

def filter_list(revisionlist, search_str):
	passed = None
	for element in revisionlist:
		name = element.Name
		if search_str == name:
			passed = element
	return passed        

SelNames = ['Wall Types', 'Door Types', 'Casework Types']       
    
form = SelectionForm(SelNames)
form.ShowDialog()
SelectedType = form.selected

options = OpenOptions()
options.DetachFromCentralOption = DetachFromCentralOption.DetachAndPreserveWorksets


if SelectedType == 'Wall Types':
    FilePath = 'C:\Downloads\\project1.rvt'
    modelPath = ModelPathUtils.ConvertUserVisiblePathToModelPath(FilePath)
    docFam = app.OpenDocumentFile(modelPath, options)
    ElemCol = FilteredElementCollector(docFam).OfCategory(BuiltInCategory.OST_Walls).WhereElementIsElementType().ToElements()

elif SelectedType == 'Door Types':
    FilePath = 'C:\Downloads\\project2.rvt'
    modelPath = ModelPathUtils.ConvertUserVisiblePathToModelPath(FilePath)
    docFam = app.OpenDocumentFile(modelPath, options)
    ElemCol = FilteredElementCollector(docFam).OfCategory(BuiltInCategory.OST_Doors).WhereElementIsElementType().ToElements()
elif SelectedType == 'Casework Types':

    ElemCol = FilteredElementCollector(docFam).OfCategory(BuiltInCategory.OST_Casework).WhereElementIsElementType().ToElements()
else:
    print('Select Element Type')
    
newwalltype = []
newwalls = []


for e in ElemCol:
    tcheck = Transaction(doc, 'transfer element')
    tcheck.Start()
    try:
        eleName = Element.Name.GetValue(e)
        newwalls = e.Duplicate(eleName)
        newwalltype.append(e)
    except:
	newwalltype.append(None)       
    tcheck.Commit()
    
print(newwalltype)

What issue?

Hi,

duplicating an ElementType just operates on the same file.

You need ElementTransformUtils.CopyElements to transfer the types from one Revit file to another one.
