    103103The first and most obvious reason we can't just use a simple Cut and Paste tool is because the data values we want to transfer seldom map to the same (x,y) coordinates on any two data sheets.  In order to know which data values to transfer we have to first know enough about the data sheets and underlaying databases to know which values are involved.

    105 The second reason we can't just use a simple Cut and Paste tool is that mathematical transformations are sometimes required, such as conversion between Metric units and Imperial, as in the data sheet example above.  The third reason is that engineering judgment is often required.  All of these actions are trivial if you have the right context.  We have many thousands of design engineers doing this all day, every day, and generally, they are good at it.  But we rely so much on context to convey meaning that we cannot trust machines to make the right decisionsm on their own.
