Ok I placed a familyinstance now how do I adjust its parameters?

[scowsert]

Feel free to point me to an SDK sample but I just can't figure this out.

I place the family instance.

Autodesk.Revit.Elements.FamilyInstance Gplate =
doc.Create.NewFamilyInstance(
p, s, nonStructural );

Now I want to change a parameter in it called "Beam Depth" how?

Yes I'm a newbie attempting to fight the good fight.

Thanks Sage

Edit: nevermind found my answer
