This bottle was inspired by a model submitted by a fellow engineer Sasha. I referenced Sasha's BP500_bottle. For this initial study I specifically focused on achieving a smooth transition from the shoulder up into the neck. This model is a work in progress, but I thought I'd upload it.

The native file is Creo Parametric 1.0 and I used a combination of technical surfacing and ISDX free-form surfacing techniques.
