 Paste a parameter without the formula which defines it.
For example:
Holeplus= 15 = Diameter + 10 will be
pasted as Real.i = 15
(if the With Value box is selected)

 Paste a parameter as well as the formula which defines it, but only
if the parameters referred to in the formula are also selected in the
copy.
For example:
Holeplus= 15 = Diameter + 10 will be pasted
as Real.i = 15 if the Diameter parameter does not belong
to the items selected for the copy
but HolePlus will be pasted as Real.i = 15 = Real.j + 10
if Diameter is selected in the copy (use multiselection).

 Paste a parameter as well as the formula.
Holeplus= 15 = Diameter + 10 will be pasted
as Real.i = Diameter + 10
