Eval limitations?

Hello John,
I am in limbo between academic positions and have lost access to Rhino but need it urgently to work on a project. The project is very simple and is mostly to open an stl. file and then do some section cuts and export to AutoCAD. Are there any limits to using the free trial version?

If you have already used up your one shot at the 90-day eval, sorry.

If you haven’t used the eval before, then it’s the full product with no limitations for 90-days, then loses the ability to Save/Export or load plug-ins.

My apologies, I thought it was for mac. Thank you for your help John! Much appreciated!
