Kumpix is more than a drawing program: it is a jewelry design workshop that measures everything from the order to the casting. The model comes with its casting check, thinnest wall, gram weight and stone report; customer approval and production files are prepared in the same place.

Kumpix
Kumpix
Cast-ready jewelry design
Designer: Measurements are worked out by hand, and stone seats and wall thickness cause trouble after casting.
Sales: Customers approve without seeing the model, and gram weight and price are guesswork.
Casting and workshop: Supports, trees and wax weights are prepared from scratch for every job.
Workshop owner: No one can tell whether an order is in design, casting or polishing.
What jewelers need
is one program that measures from order to casting
not scattered work

measurements worked out by hand, gram weights guessed, customer approvals lost in messages and trees rebuilt for every casting.

The customer's request
Write the stone, metal, size and style in a jeweler's words: points, karat, ring size, prongs. The assistant takes the measurements from you and asks for anything missing.
Model from a photo
Add the photo the customer brought; Kumpix produces a first model. A photo gives no measurements: add the ring size and metal next to it.
Measurements and ring size
Turkish, US and European ring sizes are converted to the inner diameter automatically. Top, front, right and perspective views are open at the same time.
Choosing stones
Enter the carat for a solitaire or the carat per stone for a five-stone ring; total carat and stone sizes are calculated.
Metal and karat
14k, 18k, 22k; yellow, white and rose gold, platinum or silver. Change the metal and the gram weight updates instantly.

A model from one sentence
Type “1 carat solitaire, 6 prongs, size 16, 18k”. The model is drawn, with its casting check and gram weight alongside.
Refine by chat
“Make it white gold”, “use 4 prongs”, “thicken the shank”: the assistant changes only what you ask for.
The assistant explains
After every model it tells you in a short sentence what it drew, which values it chose and what you can change.
Photo + size + metal
Send the photo and the measurements together; it estimates the stone's carat and says clearly that it is an estimate.
Ready-made order examples
Start from the examples on the welcome screen: solitaire, eternity, signet, plain ring or a model from a photo.

Showcase collection
Casting check
Open edges, body count and metal volume are checked on every change; when all is well it says “Ready for casting”.
Thinnest wall
The thinnest point of the model is measured; you are warned if it drops below the limit.
Gram weight and alloys
See side by side how many grams the same model weighs in 14k, 18k, white, rose and 22k gold.
Stone report
Stone count, sizes and total carat; quotes are prepared from this report.
Resizing
Change the ring size; the inner diameter and the size and number of stones are recalculated together with the band width.

Stone report

Stone count, sizes and total carat are ready for every model; quotes are calculated from your editable stone catalog.

Bead rows, knurling, hammered and sandblasted textures; patterns flow over the surface and are carried into the model that goes to casting.

Stamps and monograms

“585” and “750” karat stamps, logos and monograms are cut into the shank.

Autosave

The document is written to disk on every change; if the program closes, you continue where you left off when you reopen it.

Text on a curve

Place names and dates along a curve on the inside or outside of the ring; the text is cut with an embedded font.

Customer approval link

Your customer turns the model in 3D on their phone and answers “I approve” or “I want changes”; the reply lands in the app.
