Copying sketches

Is it possible to copy a sketch basically right on top of theold one without all the constraints and dimensions back to themodel becoming dangling? It is very frustrating to have to reattacheverything when all I want was a copy that changes by maybe onedimension (for now).

To clarify - I have a sketch that is similar to another sketch thatI will need. I need them to stay independent, but I would like tonot have to redo the work I just did. I can copy and paste thesketch onto the plane that I need, but I then have to go fix allthe dangling dimensions and constraints that locate the sketch inthe model. Is there a way to make a copy that will initially beright on top of the other sketch, but that I can then go edit andchange the one or two things that I need to be different?
