Many times I see forum questions looking for help with part or assemblies. The part or assembly is attached (much of the time, anyway). Many of the questions would attract more respondents if there is some way to see the component that they are talking about.
For a proper answer, you have to open the part in Inventor. There is no question. But I would be more willing to do that if I could see the part lined up with my interests/skills/knowledge base.
My idea is that the Inventor Forums have a way to submit the part in such a way it gets stored with a generated link to Autodesk Viewer. Then you can see the question better. For most people that would trigger a increased desire to help. If the link expires after one/two/three months, there is no loss of information because the part and assembly files are still there.
