I downloaded a human head part off of the website GrabCad, but it said I needed an Advanced License to actually work on the part. Are there any downloadable parts that will work with the student edition of Creo?
I've never had to use a student version of the program, thus don't know what input options there are, but does the place you're getting models from have a STEP file format option? That's a way to get the model, though it import as one feature, without the model tree of features that the native file format model might have had. This is the file format I usually use to get models for purchased components, like from McMaster-Carr, etc.
