where to find the "AdskPrecastApi.dll"

[C496365993]

AdskPrecastApi.dll,this dll is designed for precast,and i want to do something onPrecast,but i can't find this dll, can't reference to the "using Autodesk.RevitPrecast.Split".

My Revit version Revit 2021  OS:WINDOWS 10

This was included with Revit from 2021 onwards, prior to 2021 would have been located similar to below if it was installed (my research leads me to believe):

C:\Program Files\Autodesk\Structural Precast for Revit 2020

Now it looks like it is probably this one post Revit 2020:

C:\Program Files\Autodesk\Revit 2021\AddIns\Precast\Autodesk.Precast.API.dll

No documentation however but has the 'Split' namespace.
