Lathe Studio
Will that curve look right once it is round?
A profile drawn flat on paper is not the shape you get. Revolving it changes how the eye reads the curve: a sweep that looks generous on the page can come out slack in the round, and a foot that looks delicate can vanish entirely. Draw the curve here, set the wall, and turn it over before you commit a blank to it.
The profile, in the round
Drag a point on the profile, or focus it and use the arrow keys; the 3D piece updates as you go. Halve it to see whether the inside follows the outside. Three things it will not settle: the grain is a picture laid over the shape, the wall is a number rather than a test, and scale is not shown — a form that reads well at screen size can be clumsy at fourteen inches.
The 3D view needs WebGL, which this browser has turned off. The profile still works.
