Watch Live SWW2017- is it free?

Not really.

The convention is mostly for training  and the training covers all kind of topics you can think of.  Where else you can get that kind of training (3 days) for the amount of registration fee???

Food, beverages, t-shirts, training from beginner to advanced and the biggest advantage is networking (knowing people that are experts and being able to tap a little bit of that knowledge because they know who you are). For all of this it is a minimal cost.

What you watch (free) is general session, not training

Chika,

SolidWorks is live streaming the morning General Session.

There is much, much more to SWW than what is streamed live in the morning General Session.

FWIW...
