Hi Jerome, Hi Curt, Thanks for the input, I changed the
\setdoublesep{0.2 em} % 'Bond Spacing' \setatomsep{1.45 em} % 'Fixed Length' \setbondoffset{0.1 em} % 'Margin Width' \newcommand{\bondwidth}{0.08 em} % 'Line Width' \setbondstyle{line width = \bondwidth} \setcrambond{2pt}{}{} to \setchemfig{bond style={line width=0.08 em,red!70}} \setchemfig{chemfig style=red} \setchemfig{double bond sep = 0.2 em, atom sep = 1.45 em, bond offset = 0.1 em, cram width=2pt} It gets closer to what I want, Thanks again, lina On Fri, Oct 8, 2021 at 5:38 PM Curt <cu...@free.fr> wrote: > On 2021-10-08, lina <lina.lastn...@gmail.com> wrote: > > > > *l.24 \setdoublesep {0.2 em} % 'Bond Spacing'* > > > > > > I'm reading that the '\setdoublesep' macro is obsolete and has been > replaced by '\setchemfig{}'.
