Foundation Tag Rotate to match footing ElementTransformUtils.RotateElement(doc, tag.Id, rotationLine, rotateValue);

The below code runs without error. However, the tags are not rotated via the below code.

ElementTransformUtils.RotateElement(doc, tag.Id, rotationLine, rotateValue);

Foundation Tags do not rotate with the components prior to Revit 2022 (although I haven't tested it in Revit 2022). To get around this, you would have to create a custom tag with the label already rotated. Or you can just keep the tags horizontal and use an arrow to point to the element you're tagging.

Hi, before running the code try go to the family editor (edit family) of Structural Foundation Tags and go to the "Family Category and Parameters" window.

Try to check the setting "Rotate with component".

Save or load the family back into in the project document and then run the code.

I tried this, and either way, it has no effect in 19 & 20? In Revit 21 & 22 it works well. I had hoped the API could get the job done. Maybe not. Thanks for the reply @StephenSmith-WPM & @so-chong .
