if I upload an object but I don't want it to be downloadable what do I do?  I just want to use your viewer , not give file to others.

Reload the *.obj's files with check-box to analyze your upload, checked. It will give you most issues with your files. Fix ALL errors and replace the package again.

How does that answer my question ? Maybe your answering my other post.

Sorry, I misread the question. We do not have that option.
