What’s the best way to form a spout on a glass, such as in: [image] 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 ni…

[image] josh1: Oh, one basic question. It looks like you revolved the curve to generate the basic cup surface and then cut out a rectangular section. Into the cutout section you attached the spout construction. Am I reading that right? Yes, I extracted isocurves to get the trimming ‘rectan…

Hi Josh, Here’s another approach as well. I do like Pascal’s form and it uses some great surface modeling techniques. This example is a bit simpler and only uses a few commands (ArrayPolar, Loft, BlendSrf). [image] [image] spout_easy.3dm (653.7 KB)

Hi Pascal, I’ve extracted three isocurves - one horizontal closed curve (a circle), and two vertical closed curves spaced apart a bit. How do I go about trimming out that “rectangle” (where the rectangle extends through the top of the object as in your example)? I tried “trim” command from the su…

Hi Josh- see if this helps - http://screencast.com/t/JaDpwg9a5zxP -Pascal

Hi Pascal, I seem to be having trouble making that work for a revolved closed curve. I attached a simple example with the isocurves marked in green. Maybe it’s because each isocurve is a closed curve and the “rectangle” is a volume in that case? Via multiple uses of “trim” I can produce three su…

Hi Josh- you’ll need another ‘around’ direction iso on the inside to form a UV rectangle. -Pascal

Pascal: Thanks, that worked. Will try the rest of your suggestions.

Brian, thanks for the alternative approach. I want to keep tight control of what parts of the vessel are deformed to form the spout and also the curvature of the spout, so am leaning towards Pascal’s approach, but your approach looks simple for situations without these concerns. It’s cool to accum…

[image] josh1: Will try the rest of your suggestions. I’d be inclined to do this separately inside and out, and then make the rim. -Pascal

[image] pascal: I’d be inclined to do this separately inside and out, and then make the rim. You mean revolving an open curve for the inside/outside, then forming the inside/outside surfaces using your technique, then doing a rim that joins the inside and outside? What’s the benefit over rev…
