Revit API transform "cannot access with an instance reference"

Question

I'm experimenting with transforms. And trying to perform and store multiple transforms, but unable to probably due to the static property of transforms. Something like this:

Wall wall = doc.GetElement(id) as Wall;
BoundingBoxXYZ wallBoundingBox = wall.get_BoundingBox(doc.ActiveView);

//Original
Transform originalTransform = wallBoundingBox.Transform;

//Translated
Transform translatedTransform = originalTransform.CreateTranslation(wallBoundingBox.Min);

Error msg: "Member 'Transform.CreateTranslation(XYZ)' cannot be accessed with an instance reference, qualify it with a type name instead."

Are there any workarounds for this?

according to http://help.autodesk.com/view/RVT/2018/ENU/?guid=Revit_API_Revit_API_Developers_Guide_Revit_Geometric_Elements_Geometry_Geometry_Helper_Classes_html] you need to use Operator* - Multiplies two specified transforms. — AakashM, May 01 '19 at 09:01
Interesting approach! I tried to test ways to get a transform using XYZs, but cant seem to find a way, any insights? — Han, May 01 '19 at 10:01
Sorry, not a system I've ever used, I was just reading API references... — AakashM, May 01 '19 at 10:25

CreateTranslation is a static member of the Transform class.

Use it like this:

Transform translatedTransform 
  = Transform.CreateTranslation(
    wallBoundingBox.Min);

Is there any way I could store the translatedTransform in a variable, and perform another translation/ rotation on the variable instead? – Han May 02 '19 at 09:02
It is already stored in a variable, in `translatedTransform`! – Jeremy Tammik May 03 '19 at 10:30
