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) [image]

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… [image]

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

or this :wink: [image] Importing text from CAD to REVIT Yeah sure, I’m using netDXF library, so the process involves exporting the import instance to DXF, parsing with the netDXF library then converting the text objects to strings and origins to Dynamo points.

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()

Thank you very much for your comment, I have ideas that you could use, but I still don’t understand very well how the code could interact with Revit using the code in PYTHON SCRIPT. Could you share a little more about it, since the “AcDbMgd” library to begin with I wouldn’t know how to obtain said library
