STEP File Viewer

STEP File Viewer 1.1.0 brings a redesigned interface: viewing, measuring, reviewing and exporting STEP / STP / IGES 3D models on iPhone, iPad and Mac is now smoother. Redesigned interface • A two-row toolbar; on larger screens the main tools are labeled: Open, Notes, Measure, Section, Explode, 2D views, Export • Improved Dark Mode: menus, the sidebar and dialogs follow the system appearance; alerts now use the app's own style • The start screen opens a model or a recent file directly, and loading shows clear progress • Section, Explode, 2D views and other modes show their status at the bottom; tap × or press Esc to leave them • The top menu bar stays visible, and Share, Guide and more now live in the More menu; features that need unlocking are marked PRO Fixes and refinements • Exporting to STL, OBJ, glTF, GLB or USDZ restores the complete solid model first: section cuts, 2D views, exploded layouts and measurement markers no longer end up in the file, so exports open correctly in other apps • Export and import Review Notes backups to move notes between iPhone, iPad and Mac; an import previews the changes first, and an older backup never overwrites newer edits (unlocked together with review report export) • Mac: opening a model from recent files works again, and clicking empty space clears the selection; keyboard shortcuts include ⌘O to open, G to toggle the grid and D for model details • The Measure, Review Notes and exploded-parts panels no longer overlap • Point to Point and Point to Plane measurements no longer create 0-distance records
