Build a Greek key vase from a plain new bowl — shape it, choose the woods, draw the face pattern.

Add a lid and a finial, lay a motif round the rings, and paint segments by hand.

Segmented bowls

Work from the shop — the kind of piece a cut list has to be right for. One segment out of true and the ring will not close.

Segmented sapele bowl with a chevron feature ring in padauk, zebra, maple and ebony — Chevron inlay — sapele with padauk, zebra, maple and ebony feature ring.

Tall segmented vessel with a diamond and cross feature ring in dark and light woods — A diamond feature ring. Every segment has to land, or the ring will not close.

Segmented bowl with a feature ring spelling the letter L, photographed on a maple table — The letter L for my sister Loretta.

A patterned segmented vessel still mounted on the lathe, being turned — Still on the lathe. Finished in wax polish.

Finished segmented sapele bowl with a brick-work feature ring in red and black — **After:** the finished bowl — sapele, with brick-work feature ring.

The same segmented bowl blanks before turning, glued up and rough-shaped on the bench — **Before:** the same glue-ups, not yet turned. The profile is still buried in there.

What the desktop version adds

The browser app and the desktop app are the same designer. The desktop one adds colour 3D printing, the Blender export, the cut layout sheets and unlimited printing — and it works offline.

Draw the half-profile on the left — the 3D bowl and the full cut list build themselves. Maple and ebony, 20 segments a ring.

Looking straight down inside the 3D preview of the checkerboard bowl, showing how the segment pattern lands ring by ring — Tip the preview and look straight down inside — see every joint land before you glue a single ring.

Change the woods, the segment count, the stagger — cherry and ebony here, 24 segments a ring, recalculated live.

Inside view of the cherry and ebony bowl showing the staggered joints and solid base — The inside tells the truth: stagger, joints and the solid base, checked from every angle before you cut.

Browser or desktop — what each one does

The same designer, two ways to run it. Designing is free in the browser; the numbers and the printed sheets are what a cut list pays for.

Why $199?

Segmented-turning software runs $89 to $169, and it does one job well: the numbers for the lathe. Segmented Bowl Designer gives you those too — then takes the same design all the way to a finished, printable, glue-ready result. One licence covers the whole job, from the first sketch to the printed sheets.

Questions before you buy

Do I need to install anything?

Not for the browser app — it runs in any modern web browser. The desktop app is a Windows download you activate with your order number, and it works offline.

What files can I export?

Both apps print the cut list, true-size ring templates, pattern-cut guides, the stave, lid and floating-base sheets and a quote, and both export an STL for 3D printing. The desktop app adds a colour 3MF for multi-filament printing with real inlay pieces, a Blender (GLB) export, and the cut layout and strip-and-mitre sheets. In the browser these need a cut list; on the desktop they are unlimited.

Do I need to know CAD or 3D software?

No. You draw the half-profile and the app builds the 3D bowl, the ring stack and the full cut list for you.

Is the desktop version Windows only?

Yes — the desktop app is Windows. The browser version works on any computer.

Can I try it before I buy?

Yes. Designing in your browser is free — profile, rings, woods, patterns and the 3D preview. A cut list is $6.00, and your first purchase includes one bonus cut list. The $199 desktop licence is a one-time purchase.

Can I get a refund?

The desktop licence comes with a 30-day money-back guarantee, and unused cut-list credits are refundable within 30 days — see our Refund Policy.
