>My choice was moi3d and that was and is one of the best investment in my workflow
I purchased MOI back in May of 2012
Don't get to work with it as much as I would like, as my main app that I use here at work is modo.

>I look at moi3d like a liteweight version of rhinoceros3d,cause of the similarity of the tools and modeling approach.
Michael was the programmer at Robert McNeel and Associates who developed Rhino.
Here is a link to an interview http://blog.novedge.com/2008/07/an-interview-wi.html

>That is the main aim of my modeling,but I choose very complicated concept car,to see how I can solve certain issues.In the past when I learned to work with 3ds max,I saw heavy tasks are the best way to progress in your software learning.
I applaud you for taking on a complex project like you've done. It's good to stretch yourself.

Here is a model of the Firebird, developed by Northrop Grumman and designed by Scaled Composites.
I have been working on when I get the chance.

Again, best of luck to you on your model.

Take Care,
