I am developing a smart public toilet focused on everyday public convenience and need a complete 3-dimensional concept that clearly illustrates both the exterior architecture and the technology-rich interior. The model must show how the automated cleaning system, touchless controls, real-time occupancy indicators and an online payment solution fit together in a compact, user-friendly space. I will share exact dimensions, component specifications and branding guidelines once the project is awarded; an NDA is required at that point and all shared information must remain strictly confidential. Deliverables I expect: • A detailed 3D model (native file plus export to OBJ or FBX) suitable for refinement in AutoCAD, Revit or similar tools , solidworks. • High-resolution, photo-realistic renders covering day and night scenarios, interior and exterior • A short walkthrough or exploded-view sequence that explains the cleaning mechanism, sensor placement and payment module integration • Source files organised so engineering, MEP and signage teams can extract drawings without rework Please ensure geometry is clean, textures are logically named and the file hierarchy is tidy; that will be my primary acceptance criterion along with visual accuracy. If you are comfortable signing the NDA and can hit these quality marks, I look forward to collaborating.
