I'm trying to reproduce the geometry of a "duck shaped" wine decanter.
To do this, I've traced the contours of the glass body, and have found the centre axis of its shape. From this, I've Follow-Me'd a decagon, or 10-sided circle, along said centre axis, and used the Scaling Tool to reach the topmost contour line in the volume.
The problem is, I can only eyeball the scale of each plane, but I'd need to infer it in order to obtain manageable curves, i.e. products of formulaic construction, in order to build tenable surfaces from these.
Is there any way to go about this?
