Will Rhino completely end/not charge after my 90 day subscription ends?

Unlike other services Rhino will simply terminate my services correct?

Rhino does not have any subscriptions. There is a free one time 90 day evaluation process which is available at Rhino - Downloads Rhino will continue to run after the free 90 day evaluation period ends but you will not be able to save, export, etc. To be able to save, etc you will need to buy a license.

Just to clarify another point: Rhino is an application that you download and install on your computer. It runs on your computer, not on some server over the net. While it will run without a network connection, it does use the network for accessing help files, downloading plugins and a few other things.

If you download it and install it and then ignore it until the last week before expiration you probably won’t get much of an evaluation. But if you wait to download until you know you will have an average of 2 or 3 half days a week to experiment and learn, 90 days should be plenty of time for you to discover how much use it would be for your purposes.
