Transform a polyline

[george1985]

Hello,
I would like to move/rotate a polyline object.
Through googling, I found out that ElementTransformUtils class contains the functionality to achieve this, but only for the elements which have already been added to the Revit document (like ModelCurve for example).
My polyline exists only in memory. Is there a method which would move/rotate it?
I see there is a GetTransformed method, but I am not sure how to use it.

Any help is welcomed.

Okay, I think I got it:

moveVec = XYZ(10,0,0)
transform = Transform.CreateTranslation(moveVec)
polyline2 = polyline.GetTransformed(transform)

The same for rotation, just Transform.CreateRotationAtPoint method instead.

But what if I want to rotate a point (XYZ) around another point?

XYZ does not have a GetTransformed or any other '...Transform' method.
