but actually no work Text_value still show empty list

Hi,
it is not possible to get the text value from a ImportInstance (dwg link) by analyzing its geometry

you can use the BimorphNodes package (that uses another process)

Hey,

LinkDWG also has a few nodes that you can dig around in to see the code… It’s using COM objects and you need to have AutoCAD open to get them.

Hope that is of interest…

I don’t want to load that node to every pc so I decide to writing code by my self but thank for this suggestion

Thomas Mahon describes possible methods here… Can anyone pls change this code and add insert IN[2] = LinkDWG - #2 by Thomas_Mahon

Revit has the AcDbMgd.dll library available.

You could side load the DWG file and scrape for text objects using the Autocad API

clr.AddReference("AcDbMgd")
from Autodesk.AutoCAD.Runtime import *
from Autodesk.AutoCAD.DatabaseServices import *
from Autodesk.AutoCAD.Geometry import *

# get DWG path example
dwgpath = IN[0]

with Database(False, True) as db:
    db.ReadDwgFile(dwgpath, FileShare.ReadWrite, False, "")
        with db.TransactionManager.StartTransaction() as t:
            # Do AutoCAD API stuff here
            # Commit changes
            t.Commit()
