Asked before you did — answered straight

They are manufacturing-plausible, not die-cutter-certified. Geometry follows standard conventions — FEFCO 0201 for the RSC, proper glue tabs, dust flaps, slots, and a 3 mm bleed — and it has not been validated against any specific converter's tooling. Confirm tolerances with your printer and run one physical proof before a production run. That is true for any structural file, from any tool.

The six boxes: mailer, tuck end, RSC, drawer, pillow, and gable. The five containers — Boston round bottle, jar, beverage can, stand-up pouch, cosmetic tube — return no dieline by design (there is no folding blank to cut), and the dieline view says so when you open one of them.

Share links encode the scene in the URL, and URLs have practical size limits. Artwork larger than roughly 1.5 KB as a data URL — uploads and multi-KB prints — is stripped when the link is created; the toolbar warns you at that moment. Sub-KB SVG symbols and patterns survive. For artwork-heavy scenes, keep the scene in your local save or store it as an account project via the API.

Not yet. PDF export opens a clean, print-themed sheet in a new window and triggers the browser's print dialog — you choose Save as PDF. The sheet is print-ready, but a native vector PDF writer is still future work. For CAD-grade output today, use the DXF export.

High-resolution captures depend on GPU memory. On weak or busy GPUs a 4K snapshot can fail silently to a blank image. Drop to 2K, close other GPU-heavy tabs, and try again.

No. Undo holds 50 entries in memory and resets on reload. What survives is the autosaved snapshot: the latest state of each template, restored when you reopen it.

It is read-only by chrome, not by enforcement — the editing panels are hidden in the iframe, but the underlying scene state is still live. Treat every shared or embedded scene as public: never put confidential artwork or unreleased product names into a scene you plan to link.

A tiled PacFully wordmark across the image plus a banner, composited into the exported PNG itself. It applies to raster renders on the Free plan only; Lite and above export clean, and dieline vector exports are never watermarked.

Millimetres, end to end. Editor dimensions, board thickness (0.2–1 mm for boxes), dieline coordinates, DXF output, and the dimensions stored on projects are all mm, with decimal precision. Scene units in the 3D viewport are scaled from mm internally — you never have to think about them.

Yes — galleries, the editor, local saves, share links, and exports all work signed out. An account adds the dashboard workspace and the account API (projects, assets, developer keys). See Saving & dashboard.
