Hi everyone.
I'm korean student, now seeking for a job so studying technology license, and
learning CATIA at academy in Gangnam, Seoul.
In my dinner time, I just think about it's so hard to do a Surface modeling (especially 3D curve - ex) weird Mouse, curvy bottles etc.) 
So I think, it will be a good thing that in VR, if there CATIA system be.
Like an "IRON MAN" movie, we can design with our hands, and just drawing -> it will be nice surface modeling (if you have a good at drawing).
We can do this thing at real life with 3D pen, but it has no constraint, and also we cannot drafting.
So if CATIA like systems, maybe in the VR world, we can give constraint at this system and make it easy to drawing surface and whole modeling.
I hope when this system in our life, humanbeing will grow more at modeling and all of design.
Thank you for reading my idea.
