Over the past couple of years the UK based Cave Surveying Group (CSG) have run a number of training courses to teach DistoX Paperless surveying and drawing up with Therion. I have now written the first draft of a training guide based on the data gathered on one of these courses. The CSG also have a new website where we are starting to publish online. The CSG homepage is http://cp.cavesurveying.org.uk/ The training course and example data can be found here: http://cp.cavesurveying.org.uk/index.php/articles/3-therion-tutorial I would welcome any feedback on the content of the tutorial as it is an on going project to improve the content to cover more features of Therion, and to correct any mistakes in the parts I have written so far. Perhaps someone with wiki editing permissions could add a link to this training material to the therion wiki too? Footleg
