Have been a Rhino user for years, since V1 and love it.
Bongo on the other hand is one of the most unfriendly and counter intuitive products I have ever used.
I can spend an hour with multiple attempts to perform what should be a simple task.
I usual end up exporting my models to another program for what should be a simple mechanical simulation/demonstration.
Hoping to see big improvements in B3, or a least an alternative plugin.
Everyone hates the user interface of Bongo. When I make a mistake, Bongo randomly scatters animated objects and its precalculation freezes Rhino for a minute. Help file documentation (especially about inverse kinematics) is incomplete.
