OpenSCAD Vase (rotate_extrude) example
Profiles & patterns
Lesson 12 of 22
Revolve a closed wall cross-section around Z without crossing the axis.

How this model works
For rotate_extrude, profile X is the radius and profile Y becomes height. The polygon walks up the outside, returns down the inside, then closes across the bottom. All radii are nonnegative, and the inner profile stops above z = 0 to preserve a floor. Wall thickness here is a radial difference, not a constant surface-normal offset. This decorative model is not validated as watertight or food-safe.

Make it your own
Narrow the neck while keeping neck_radius greater than wall. Draw the polygon on paper and identify which two segments form the floor.
Change one parameter at a time and inspect the result. Use the workspace reset action to return to this lesson’s original model.
