Howdy folks Pardon any implicit or explicit stupidity in advance. I'm an EE major taking a class in Autodesk Inventor, and I'm probably going to do a motorcycle frame for a midterm project. While it will not be required, I'm curious to see if I can make something roadworthy. Does any government body and/or engineering association publish specifications for this particular thing? I found something by NHTSA about _imported_ motorcycles, but nothing yet about manufacture. Thanks much in advance << Personal information deleted by Moderators >> PS - what is the general take on Inventor? I have to say, after hating Autocad with the burning passion of a thousand suns I find it to be a very welcome alternative. I only wish it did thermodynamic simulations, but I guess that's what multiphysics is for.
