Interactive 3D PDF Animation

I already have the full 3D model of my product in a standard CAD/OBJ/STEP format, and I need it turned into an interactive 3D PDF. When someone opens the file the product should begin a smooth, continuous rotation automatically, and each key component must be hotspot-enabled so a simple click reveals its label or brief description inside the viewer. The final PDF has to run entirely in Adobe Acrobat Reader without extra plug-ins, keeping file size reasonable for email sharing. Please make sure lighting, materials, and viewpoint are set so the object looks clean and professional from the first frame. I will supply the native model and a list of part names; you return one ready-to-share 3D PDF plus any source files you create (e.g., Composer/SimLab/Acrobat settings) so I can tweak later if needed. Deliverable checklist: • 3D PDF with autoplay rotation • Clickable part hotspots showing labels/details • All source setup files I’ll provide feedback after the first draft; final approval once everything functions as described.
