Made for Mechanical Engineering
Mechanical & product engineers: ship the next format without installing CAD
A supplier sends STEP/IGES, or you need to hand a model to the shop or a 3D printer? Convert, repair and deliver in the browser.
Local-first: your drawings do not leave the device by default; optional cloud is clearly flagged
STEP/IGES/STL/OBJ/3MF/GLB conversion plus Boolean, hollow, simplify and repair
No SolidWorks/Fusion install required to view and explore supplier files
CAD format exchange
Convert supplier STEP/IGES and mesh formats; inspect structure before handoff.
