That's a good example of a UI that's really quite difficult for a beginner to get started with - just lots of pretty small icons everywhere, no text no labels no labeled categorziation...

Just icons themselves do not convey enough information for a beginning user to really have much idea what they do - when a beginning user browses over that screenshot that you just posted, they don't think "oh that's the function I need", it's more like they're looking at a bunch of indecipherable Egyptian hieroglyphics and they don't have a translation for it... ;)

That UI can work ok for a trained user who will invest many hours of studying and taking classes in order to learn how things work but it's quite baffling for other kinds of users who do not have a whole lot of time (and $$) to invest to go to training.

The level of confusion that a UI like that presents to beginners can be quite hard for an expert CAD user to relate to very well.
