McNeel, if you want to survive in the jungle of the CAD software should do faster. The timing is an important factor in the selection and purchase of software. Five years of development would be justified if the CAD would provide innovative and advanced modeling tools.
The development is too slow: subD at an early stage (many competitors software for several years have this feature); modeling tools, the usual, always the same (apart from minor improvements here and there and the welcome news of the shelling). Too focused on marginal factors and soon turned to modeling and editing of surfaces, such as: rendering, grasshopper, various views not needed, and so on.
Also MOI runs faster, whereas software is a younger and less mature, will not have the same number of Rhino tools, but is able to model all with simplicity and discreet power, as Rhino… and coast 1/5 about!
Each new version: the same bug to be fixed, the same problems, minor adjustments and additions, but nothing revolutionary.
From a point of view of marketing: why you should buy the new version of Rhino? What possesses innovative than 5 Rhino? A few more options could justify its purchase?
I ask all of you without any controversy…
