Have a look here: Rhino 6 Wishlist - Gumball "Align to View" Mode
I’d second @jean77flip’s comment about T-Spline drag mode, it’s really very useful, especially for the sort of stuff you’re talking about, rene1.
Take a look here as an example, it works really well with the plugin (which is EOL next month): https://youtu.be/AFumwfl5beI
Any chance of this functionality being added to V6? (hopefully before the sub-d development/release)
