I'd like to import a capital delta from the eulervm package without importing the whole package. I've tried to follow the instructions given by Alan Munn in Importing a Single Symbol From a Different Font, but I wasn't able to find the "loading-settings" for eulervm on my own, and I got stuck.

Thank you in advance for any help.

What do you mean by “calligraphic capital delta”? There's no calligraphic Greek in eulervm; are you meaning the calligraphic capital “D”, instead? –  egreg Aug 2 at 8:56
    
I just mean the capital delta shown at the bottom of page 3 in mirror.hmc.edu/ctan/fonts/eulervm/doc/latex/eulervm/eulervm.pdf. –  Dirachlet Aug 2 at 9:29

The simplest way is to import the symbol as text; the Delta is at slot 1 in the font. Using \text ensures the symbol will scale in sub/superscripts.

\documentclass{article}
\usepackage{amsmath}

\newcommand{\euDelta}{%
  \text{\usefont{U}{zeur}{m}{n}\symbol{1}}%
}

%% remove the following three lines if you
%% don't want to scale the symbol
\makeatletter
\newcommand\zeu@Scale{1.05}
\makeatother

\begin{document}
$\Delta\euDelta$
\end{document}

enter image description here
