Autodesk has worked very hard to make it nearly impossible
to post readable code in their discussion forums.
Because of that, its hard for me to look at your code, so I'll
ask you to post it as an attachment (*.cs or in a .zip file).
Also, you don't mention what error message you're getting.

I have a litte program which copies and rotates a selectionset along a curve. It works without any problems for every object except BlockReferences. If i do not transform the objects in TransformSelectionSet2, also the BlockReferences are working, i just get the error when i want to transform the BlockReferences. Does anyone know what i have to do?
