Now I understand. I tried to apply the converter to the files you were refering
to, and you are absolutely right that the converter fails.
I have been investigating this a bit and it actually turns out that the files do
not strictly follow the c3d file standard and that is why the converter stops
with an error. However, it is such a simple error in those files that it was not
so difficult to make a fix such that these can also be converted. I will have a
new version uploaded as soon as possible.
The reason why we have not seen this before is because this c3d converter is
fairly new and the WheelChairRancho model was made before the converter was.
Thanks a lot for bringing this to our attention.

Subject: [AnyScript] Re: data input question
I understand when you say how certain elements are critical for
decoding. I was trying to use a file which is part of the repository
under ‘WheelChairRancho’ called 5858_free.c3d.
When i tried to use the c3d converter with this file. I got an error
which said ‘The specified element type is undefined Aborting’.
Now i assumed that this file worked for you guys as you have included
its data in the Anybody model. I was wondering why i am getting this
error, when it worked ( i assume) for you.
I have tried the converter with another c3d file which i had and it
worked so i know that the way i trying to run the converter is
Hope this clarifies my question a bit

Could you please elaborate?
> There are a few parts of the c3d file that the converter assume are
present, but these are only the very essential parts without which it
is impossible to completely decode the file. An example is the
POINTS:LABEL group which gives the data points a label. A complete
list of these parameters and groups can be found at www.c3d.org (the
required groups and parameters). If any of these are missing, the
converter will abort and display an error.
> Besides this, it has been attempted to make a one-to-one map from
the c3d file to the AnyScript files. However, the naming policy (or
lack of such rather) in the c3d file standard caused a problem
because the data can have names that are not accepted in AnyScript.
In order to solve this problem, the converter will convert all
unaccepted characters to accepted ones. For instance a “+” in a name
will be converted to “_”.
