Hi,

When I updated the system, the following .tex code does not work, it shows the error likes this:

Hello Lina, can you provide a more minimal sample that reproduce the error ?
Best wishes,
Jerome

I'm reading that the '\setdoublesep' macro is obsolete and has been
replaced by '\setchemfig{}'. Maybe this has something to do with the
error being thrown.

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
