The SOLIDWORKS suite of software doesn't get web based file sharing until you are using PDM Professional Web 2.0. However, GrabCAD has a system called GrabCAD Workbench that does offer some ability for online collaboration for SOLIDWORKS files. It isn't perfect but for an academic project it would probably work just fine.
Would like to hear anyone's comments on using GrabCAD Workbench.
Edit: Brien McEwen shares experiences, using GrabCAD Workbench in 2018 here: https://forum.solidworks.com/message/864937#comment-864937
I'm working on a one-man project, which is intended to be shared publicly, later this year. At that time, I'd want to know of a working collaboration platform and workflow.
Note: I've successfully misused my GitHub account to keep track of the versions, so far. This works remarkably well for SolidWorks, allowing renames, occasional reverts and overall version tracking of the project. Unfortunately, since there is no way to get diffs and apply them as patches, it cannot be used for collaboration if two parties changed the same file, at the same time.
SW has a "collaboration mode", but that has more to do with how SW handles write access to files. You probably need this as well.
I've used SW on Dropbox. It's worked well for small teams (2-5 people).
