Different width of the wall with smooth transition

alexander_novikov722

Good day! I'm trying to do thicker wall on the botton of the cylinder, tried it with move face, but it is just even face offset, is there a way to add width with fall off? For now used move face and removed the step with bevel, it is looking ugly but somewhat a workaround, but maybe there is a cleaner solution? The overall wall was created with shell.
Thanks!

Loft the outer solid. Then loft remove the inner solid. Rather than a shell.

In those cases, I usually try to keep it simple and robust to later edits.

• Instead of lofting, a revolve could be used (partly): Just sketch out the desired thickness in a section sketch and revolve.
• One could create two parts (Body and neck of the bottle), shell each to desired wall tickness and then loft-add the connection (funnel).
• One could loft the massive bottle, then extrude-remove both end caps inwards (minus wall thickness) up to the transition, delete the bottom faces of the extrudes and loft only the inner transition.

All three methods would allow controlling wall thickness at all places, by e.g. applying draft to the xtruded portions or assigning variables in the sketch.

Matt_Shields, thank you for the reply! You're created two parts with different lofts (fat and thin with corrected radius of constructed shapes) and boolen from fat with thin? And how you managed loft with hard transition? I got bulge vase insted (normal to profile not helped), so I made three lofts from top part, transition and bottom and boolean them all togeather.

I did two lofts, an Add and a Remove. And I used normal to profile.
