I am attempting to create a truncated icosahedron (soccer ball) as specified in a tutorial. The tutorial shows this mesh being part of the Solids that are in Add-ons. Mesh>Solids>Archimedian>Truncated Icosahedron (see screenshot at 1:06 in tutorial). When I enable my add-ons, I do not see the same ones that he does. He's using v2.68 and I'm using v2.74. Have I done something wrong, or has it changed between versions?
In Object Mode hit Shift+A shortcut to add a new object, and in the menu select Mesh>Icosphere with number of subdivisions set to 1.
Then change to Edit Mode, select everything, hit Ctrl+Shift+B shortcut to bevel the vertices and input 0.35 as the amount of bevel and hit Enter, or in Bevel operator panel change amount type to Percent and change Amount to 33.333%
The plugin is called now add_mesh_extra_objects. To enable it press CtrlAltU to open the preferences window. On the Addons tab type extra and and check the box for Add Mesh:Extra Objects
On the add menu you'll have the option Mesh-> Math_Function->Solid
Enable the Tool Shelf by pressing T (or press F^) and select Ichosahedron.
On the vertex truncation type 0.667
