Well I am happy to report that with the new Dynamo 1.2 enhancements and the new "Element.SetLocation" node it is now possible...at least in some cases. Lets take the example of Beams that need to be offset 1' from the edge of slab.
Follow the steps in the image below and you will see that it is possible.
Note that this method is also possible with other elements and I plan to show examples if that in the future. What is nice about this method is it speeds up the align offset process, Good luck and have fun aligning with offsets!
