Create angular dimension with 3 references and equal angles

[m.walterN99B3]

Is there a way in the API or maybe a workaround to create an angular dimension with equal angles between 3 model lines?

NewAngularDimension only accepts 2 references:

public Dimension NewAngularDimension(
	View view,
	Arc arc,
	Reference firstRef,
	Reference secondRef
)

which version of Revit API do you use?  As far as I know, Revit API 2022 has already supported this in AngularDimension class.

I use Revit 2016-2026.
In the documentation for Revit 2022-2026 there is no method in FamilyItemFactory Class named NewAngularDimension with 3 references:
