Create MText

Civil3D
,
1

Hi … I am trying to add my own python script node to create MText objects in Model Space.
The input is a list of Points (output of Points.ByCoordinates Node).
Result: Civil 3D Fatal Error. Operation is not valid due to the state of the object.
Python error warning: No method matches given arguments for OnExit

You are already opening model space ForWrite, so there’s no need to UpgradeOpen() and DowngradeOpen() within the loop.

hi
if you use civil 2023 check
from

                #
                bt = t.GetObject(db.BlockTableId, OpenMode.ForWrite)
                ms = t.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite)

with

 bt = t.GetObject(db.BlockTableId, OpenMode.ForWrite)
            btrID = bt.get_Item("*Model_Space")
            btr = t.GetObject(btrID, OpenMode.ForWrite)

and
you have points dynamo or point3d

thx … I am still using 2022 . … 2022.2

Here is my very bad DYN - including the updated script you provided …
I was planning to script the MTEXT as I needed more MTEXT creation options
Since then … I have opted to use Text instead of MTEXT and all is working correctly.
Would be interesting to figure out what the problem is …
Thanks for your patience.

Hey!!! I had a chance to try C3D 2023 today … and this works!!! Thank You…

bt = t.GetObject(db.BlockTableId, OpenMode.ForWrite)
            btrID = bt.get_Item("*Model_Space")
            btr = t.GetObject(btrID, OpenMode.ForWrite)
