Cadasio: a documented CAD-to-presentation workflow
Cadasio describes a browser platform for repurposing CAD into interactive presentations. Its CAD add-ins page also lists neutral formats such as STEP and OBJ. Its assembly-instructions page describes step authoring, sharing through links and QR codes, website embedding, and outputs including images, PDFs and movies. These are Cadasio’s published capabilities; test the particular format and workflow you need.
