I exported a stl model into VRML using Accutrans. When I tried to upload the wrl model (VRML format), Shapeways says there are NodeBodyElement errors in the model. What does that mean? I downloaded Meshlab. Meshlab says I need to install Microsoft Visual C++ 2008 SP1. After I downloaded Microsoft Visual Studio from the Microsoft website, Meshlab still gives me the same message. Any suggestion.
