What’s the best way to form a spout on a glass, such as in:
I can create a closed curve and revolve it to create a cup, but I’m not sure how to then form a pouring spout. Ideally it’d be nice to be able to specify a curve the defines how the top surface of the spout curves outwards. A nice-to-have would be if the process for forming the spout preserves the volume of the solid (e.g., with an eye towards manufacturing where the spout shape is stamped onto the still-hot cup). I’m somewhat new to Rhino so may be missing an obvious tool for this.
Out of curiosity, would the same process for forming the spout in the above pic also be used in forming the spout in the pitcher at http://www.emmabridgewater.co.uk/en/uk/glassware/black-toast-glass-water-pitcher/invt/1blt011415 ?
