The script I created in an older version of Dynamo works well, but when I use the new version of Dynamo in Revit 2024, the script do not work as before.
Dose anyone know how to fix this problem？
The orange preview in Revit indicate the location of the Section Box, but as you can see in the image above, the Section Box is positioned elsewhere.

@A.C ,

you must install packages IronPython2 and 3.

You probably have different coordinates setup in this model. You’ll have to find the translation of the coordinate system to determine the “offset” needed to correct the placement.

I attempted to create a new project without any settings, but it just have an offset, I don’t know why.
