Takes seemingly forever to get 3D models on the Web –ProEngineer *  3D Studio Max *  Shockwave3D * : ~3 weeks –A medical lab scene took ~6 months to convert to X3D. Problems: –The formats are not quite complete, and lack broad acceptance VRML * : player size, performance DXF * : textures, compression, lighting, materials W3D *, HOOPS * : community extensibility X3D * : compression, streaming, multi-res –No Wysiwig Converters and players are buggy Lack of conformance (“certifications”) Time $$$  “Stuck” in CAD and DCC tools 
