using step files in inventor 2013

we keep trying to open the step files and they won’t work. any help would be great. We have found the downloadable files that someone else has created but we want to learn how to use the step files from vex. THANKS

when you place a part change the file type to .step or all and you should be fine

The File Type is automatically set to be .iam and .ipt, which does not show .step files. What I do is simply change the File Type to “All” and then open whatever files I need.
