Open OBJ on Phone

OBJ is a 3D model format often paired with material and texture files.

• OBJ files can be large text files.
• Materials may require separate MTL and texture files.
• Mobile viewers need 3D rendering support.

OpenOnPhone is for quick local inspection. It does not replace the original professional app for editing, conversion, exact layout, formulas, measurements, security review, or full workflow features.
