What it makesCopy Anchor Link

The device modeler turns measurements into a catalog entry that any project can use:

• a 3D model file (GLB), built from your numbers, with a generated finish per area and no photos or logos on it;
• catalog data: the size, the weight, how it mounts, and every port as data (its kind, face and position), so projects can show and check it.

It makes two kinds of thing:

• Devices: things with ports that you plug in, such as a router, a switch, a mini PC, a NAS or a hub.
• Parts: things that hold or mount devices, such as a shelf, a tray, a bracket, a panel, a plate or a spacer.

Your measurements are published with the entry, so anyone can reopen them in the modeler and publish a correction later.

StartingCopy Anchor Link

• A new device or part: open the catalog and choose Model a device, or go straight to /catalog/model.
• Measurements you already published, or someone else's: on the entry's page, choose Edit measurements. Your changes become a new revision of your own entry, or a copy in your namespace that credits the original. See Entries and revisions.
• A draft of yours: it opens at /catalog/model/<namespace>/<slug>/<rev>.

You can use the modeler without an account. Your work is then kept in this browser only. Sign in to save it to your account, keep datasheets with it, use live sync and publish it. See Accounts.

The workspaceCopy Anchor Link

The page has two halves:

• The steps, on the left: Device or part, Name, Shape and size, Faces and ports, Finishes and Review. You can open any step at any time. See The steps.
• Model, on the right: the 3D model, built live as you type. Drag to turn it, and click a face to edit it in Faces and ports.

Above the steps are Undo, Redo and Save draft. Every change saves by itself: to your account when you are signed in, otherwise in this browser. The status next to the step title says which (for example "saved to your account · draft ana/nas-box rev 1"). Save draft saves right away.

Good sources of numbersCopy Anchor Link

Use your own measurements and the maker's published numbers. Other people's models and photos can tell you which features exist, but don't copy their sizes. No logos or trademarks go on the model.

Mark where each number comes from (measured, datasheet or estimate) with the small menu next to it. The review counts them, and estimated values are flagged.
