Where can I find usage documentation (I'd like to see the length/offset from starting point of lines while drawing) and sources? The svn repos at http://svn.archimedes.org.br/public/mainarchimedes/archimedes/ seems out of date?
Indeed the http://svn.archimedes.org.br/public/mainarchimedes/archimedes/ repository is no longer used.
The project now uses the RCP version: http://svn.archimedes.org.br/public/mainarchimedes/rcparchimedes/.
Regarding the documentation, nobody ever cared to write one so I am sorry to say we don't have any user documentation.
Might I ask how you would like to see those information? On the status bar, next to the absolute position of the point or replacing that information?
