Unlike all other options on this list (aside from Blender which is free), Rhino doesn’t attempt to take money from you each month for using their software.
Unlike all other options on this list (aside from Blender which is free), Rhino doesn’t attempt to take money from you each month for using their software. Instead, they offer you a perpetual licence; a rare thing these days that we encourage. In addition to that, they also have an extremely generous 90-day free trial. You can still use the software after that time, only you won’t be able to save your work and any plugins you have installed will stop working until you purchase a license.
