Increasing Knowledge and Skills for Assembly Processes through Interactive 3D-PDFs

Extending PDFs with interactive three-dimensional CAD content is an opportunity to enable users with different knowledge levels to understand assembly processes. Users are enabled to manipulate CAD content by a combination of pictograms and text, without any knowledge on how to handle CAD programs. A generic structure for an interactive 3D-PDF, containing manual assembly tasks, has been developed as a so-called learnstrument. Visual, haptic and aurally learning methods are integrated in 3D-PDFs to facilitate sustainable development worldwide.
