“I have been learning Autodesk Fusion 360 to support my desire to 3D print – and wanted a way to share CAD files with others – I found ProtoTech Solutions 3D PDF Exporter to work fantastically, and also their 3D PDF viewer for my Android works great.  However, even better than how well the products work, their customer service was fantastic, as they responded to multiple questions I had daily !!  I would not hesitate to recommend this to anyone.”
