where can I download a "text" addon? I'm not very good in the subject of addons, and when I wanted to be able to add a polysphere on blender, I googled around and found an "Add_mesh_round_cube" addon which I believe should be correct. It's on the blender developer website, so I think it's quite a legitimate source:



When I selected the addon on the list (as seen above) I came to this page:



Apparently this is the python text of the addon. But I don't know how to proceed from here. Can anyone help me out?

Thanks for reading!
Select the text and copy it, then paste it into a text editor and save it as something like Add_mesh_round_cube.py (make sure to give it the .py extension).  Now you can load it into Blender like any other addon.  Open the User Preferences (Ctrl+Alt+U) and go to the Addons tab, then hit Install From File and select the file from your computer.  Then click the little checkmark next to it to enable it.

Note that, as others have mentioned, the specific addon you are looking at is already bundled in Blender by default, so you can just find it in the list and enable it.
