3D modeling from simple shapes, with the whole editor on the cover and more room open
Does Shapely 3D work on iPhone Duo?
Yes, since version 1.3: closed, the cover is the whole editor; open, the same project gets more room around it, with your selection and view where you left them.
- App Store confirmedFabrizio Brancati, the developer, in a submission to FoldHunt on October 23, 2026. The App Store seller is Fabrizio Brancati. The release notes for version 1.3.0 (released October 12, 2026) say it is built for iPhone Duo and describe the closed and open layouts. The press page has iPhone, iPad and Mac pictures, none from the Duo.
Adapted for the fold
- Closed · Outer display
The whole editor, closed
Closed, the cover holds the full editor: the shape catalog, the gizmo, point editing, booleans and the printability check.
- Open · Inner display
More room for the same project
Open the phone and the same project gets more workspace around it, with your selection and camera where you left them. Nothing is letterboxed or hidden behind the fold.
About Shapely 3D
Shapely 3D is a 3D modeling app by Fabrizio Brancati for iPhone, iPad and Mac, made for people who want to build something without learning a CAD suite. You compose a model from simple shapes, move, turn and scale them with an on-screen gizmo, snap them to a grid and read measurements in millimeters or inches as you go. A printability check tells small mesh flaws from ones a slicer would get wrong. Shapely 3D Pro, a one-time purchase, adds boolean operations, sketch and extrude, smoothing, a cut tool, face editing, repair and STL export.
Version 1.3 is built for iPhone Duo, its release notes say. Closed, the cover is the whole editor, booleans and printability check included; open, the same project gets more workspace, with the selection and camera kept, and nothing sits behind the fold.
