Well, it is possible by abusing the basal structures ONE and SIX. As an example for a 120 degree angle using SIX see the sample some messages before in this thread. However, you are right, there are things which are not present, such as certain bonds etc. Yours sincerely Tobias Hilbricht ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context
Re: [NTG-context] PPCHTeX Bug?
In my opinion - it's not only its complexity preventing the users from using it, but also it's insufficient flexibility. As long as I understood the manual (and tried to draw some formulas), it is possible to create a certain subset of images, which covers the most needs, but certainly not all of them (there's no way to make such a trivial thing as a thetraedral or trigonal angle - 109.5 and 120 degrees). see: http://www.ntg.nl/pipermail/ntg-ppchtex/2002/02.html Even the ones with lots of experience gave up. Perhaps chemistry is too complex to be applied easily without some help of graphical tools. SMILES (http://www.daylight.com/dayhtml/smiles/ssmiles.html) could be a solution, say \startSSMILES CC(=O)O \stopSSMILES producing a nice picture of acetic acid (using metafun), but perhaps still not serving all the puposes a chemist needs.

As a result of that, there isn't that much expert knowledge available. Personally, I don't understand any of it. Luckily, the only chemical stuff I have ever had to typeset could be done by cutpaste and making trivial changes to the examples in the manual.

On TeX-D-L (german ML) was last week a dicussion about a PPCHTeX bug
(at least with LaTeX), it seems that the file ppchtex.tex lost its
tail (ca. 3kB).
I told the user to ask at the PPCHTeX Mailing list, but he only got a
message,
that the list was moderated.
what tail?
Sorry, I don't like to moderate between TeX-D-L and here (and will be
off from tomorrow to end of September)...
CC to Thomas Meyer: Please care for yourself now.
Thomas Meyer wrote, some PPCHTeX code wouldn't work, the error message
was:
ppchtex.tex:3390: undefined control sequence
He uses an actual MikTeX (again, only problems with this, we should
mark it red in the wiki...)
His file ppchtex.tex ends like:
\def\cpos#1#2%
{\iftrialtypesetting
#2%
\else
\bgroup
\globalpushmacro\dowithchemical
3390
\gdef\dowithchemical##1{\hpos{#1}{##1}\globalpopmacro\dowithchemical}%
#2%
\egroup
\fi}
\fi
\protect \endinput
Tobias Hilbricht answered, the code would work with his ppchtex.tex
version from TeX Live 2003,
there line 3390 (second line from the end) had only a lonely \fi, but
the file is 3kB bigger,
but both show the same date of 1997-03-19 (I guess this date is only
the creation date and not
altered at changes, isn't it?)
With Tobias' file it worked at Thomas.
Thomas downloaded the file from pragma-ade.nl, and it doesn't work
again.
I told him to ask at the PPCHTeX list, see above.
Further Thomas wanted to draw seven-rings, and that seems not supported
by PPCHTeX.
