The software is very easy for beginners as well experienced users alike! I really like that it has so many options when designing your own customised devices or even just getting ideas from existing products (as long there's an option available).
Sometimes some features do not work quite right but this could also have something/someone else doing wrong at their end too? It would help if more tutorials were made accessible online - maybe free downloads etc.? There should always still remain room enough space between components which makes adjustments easier / quicker whilst wearing them out during use & training sessions e g shoes laces being able fit through holes rather than having gaps where one component meets another.
