I would go further and say... unless she is passionate about CAD.

My background is in science, but I work in a department with engineers of all stripes. It seems like the mechanical engineers are stuck living inside the world of their CAD systems. It's a dreary world, dominated by at most two or three software vendors making giant, expensive, training-intensive tools.

I know other engineering disciplines use tools too, but I don't think they are dominated by their tools to the extent that ME is.
