I'm sure you remember about SR 3D Builder. A rich featured CAD tool for 3D modeling of LEGO models, being developed by Sergio Reano.
This week I crossed with an explanation at YouTube, about how does he envisions the modeling of flexible parts in a 3D space.
I guess this may be not innovative in terms of professional 3D CAD tools, but definitely it will be a great advance for LEGO users of CAD tools.
It looks to me, there is a lot of B-spline mathematics running in there...
But it looks also easy and intuitive for the user (maybe after some practice). At least I guess it would have made the last TBs Technic Challenge [1, 2, 3], a lot easier for many.
However please remind this is a preview, and not yet released into the latest public SR 3D Builder version available for download.
If you thought to have seen everything, Sergio shown us the latest developments (yet to be released) on his interface to add flex parts in your models.
See them on the video below.
