Document Classes ⇒ fouriernc: Substituting A Specific Math Symbol

[Spinor]

It appears that there isn't a bold version of the math symbol \nabla in the fouriernc package. Is it possible, though may or may not be preferred, to substitute this specific math symbol by selectively choosing it from another math font package, for example, the mathpazo or lmodern package. Will appreciate any help.

TIA

have you tried just

Code: Select all

\usepackage{bm}
\bm{\nabla}

Yes, I have tried using the boldmath package. And it seems to give a "faked bold" \nabla which doesn't look very good.

That aside, my general question is how to selectively pick one math symbol font from one package and use it in another math font package. For example, if I wish to to use the kpfonts package, and do not particularly find the \sum symbol appealing, how do I substitute that symbol alone from another font package such as the mathpazo or lmodern ?

ask on comp.text.tex

You have to declare a new symbol font. Have a look at fontmath.ltx, lmodern.sty and mathpazo.sty and see how LaTeX does it.
