Shapely 3D is a native 3D modelling app for Mac, iPad and iPhone. Build models out of primitives, edit their points and faces, combine them with boolean operations, and export to STL for printing.
This is the same universal app as the App Store build — Mac and iOS share a bundle ID, so one Pro purchase covers both, and settings sync over iCloud between devices signed into the same account.
Areas worth poking at:
- Placing shapes from the catalogue, then moving, rotating and scaling them with the gizmo — with grid snapping both on and off.
- The workplane: change its size and grid spacing in Settings and check that the ruling still lines up with where objects actually snap.
- Edit Points and Edit Faces, on primitives and on an imported STL alike.
- Cut, boolean union/subtract/intersect, and marking a shape as a hole.
- Switching between perspective and flat (orthographic) view in the middle of an edit.
- Switching the system appearance between light and dark while a project is open.
- The compact layout: iPhone, and iPad windows dragged narrow. Crossing that threshold should swap the chrome without disturbing the camera.
Please send feedback straight from TestFlight (screenshot, then Share) so the device and build number travel with it.
