3D Builder

A Windows app for opening and basic editing of 3D models in formats such as 3MF, STL and OBJ. You can combine models, add basic shapes, emboss text, cut and scale, and the app detects and repairs broken meshes before printing. Suited to engineers who receive an STL file and want to check it, fix holes or prepare it for printing quickly. Limitation: it works with triangle meshes, not precise CAD geometry, so it is not suited to designing dimensioned parts.
