The programme aimed to assemble a pathfinder prototype of an online interactive educational material, which can usefully develop and enrich the educational methodology of VET by its own followable set of examples. The non-formal tool equally uses formal and informal learning methods: providing useful knowledge in a structured and evaluable form, while gaining information is performed on a pathway and in a timeframe selected by the student within a 3d virtual world, inside the Traditional Carpentry Museum.The project took as references the system of most up-to-date architectural planning software products (BIM) and the newer possibilities for interaction between the designer and client to demonstrate and analyse thoroughly the selected wooden constructions. To realise the online usage that requests no CAD knowledge nor installed products the programme exploited the opportunities of game development technologies. Beyond the support for final technical solutions, the logic of computer games also appear in the evolution and performance of the tool (gamification, edutainment) in order to achieve a more interesting, receptible and most importantly the best reachable outcome.3d models selected by partner organisations, built with the help of CAD software and then placed into the virtual space of the game engine can be considerably more easily and effectively acknowledged as it would be in the real environments of the originals. The same way the product gives a broad overview of the traditional technical solutions and realised constructions of European carpentry. Among the well-utilisable technical learning, levels of the tool with different difficulties also function as 3d interactive dictionaries of the structures.The online platform which can be further-extended after the end of the programme is a useful support for carpentry and architectural students in VET, as well as part of university education or beyond institutional training.
