Copy + Rotate in VBCommon

I've created a Brep and now I want to duplicate it and rotate the copy 180 degrees.  I've figured out how to rotate the original, for example:

myBrep1.Rotate(90* (3.14 / 180), y_vector, pt)

However, I cannot figure out how to simply make a copy of "Brep1" called "Brep2" before rotating it.  I tried the simple approach:

Dim Brep2 As Brep

Brep2 = Brep1

But the above code just makes Brep2 the same object as Brep1, and if Rotate Brep2 then obviously Brep1 also rotates.  How do I duplicate or copy Brep1 into Brep2?  This should be obvious but isn't.
