Modelling tips - Create a hollow sphere

My friend Jentina was looking for a solution to model a hexagonal shaped object, so I look at the problematic with her and here is the solution I found:

 1/ Create a GeoSphere with Geodesic Base Type set on Icosa.










2/ Add a Turbosmooth modifier, Iterations set to 1.










3/ Convert the Geometry to and Editable Poly











4/ With the help of the Graphite modelling tool bar, on the Selection tab, choose the selection by Numeric, type a value of 5 and select "<" option, that way it will select all vertices that have less than 5 edges connected to them.
Then, invert the selection.






5/ Still in sub object mode "vertex" hold CTRL on the keyboard and click on "Edges", it will select all edges connected to the selected vertices.








6/ Hold CTRL on the keyboard and click on Remove to remove unwanted edges and their vertices.









7/ Select all polygons, hit the menu icon next to "Inset", choose "by polygon", put the desired value.









8/ Leave the sub object selection and add a Mesh select modifier, choose polygon, it kept the selection history from the edit poly sub object mode.








9/ Add a Delete Mesh modifier.











10/ Add a Shell modifier and put whatever value you want for the final look of the sphere.










11/ Add a Turbosmooth modifier to get nice round holes in the sphere.










12/ That's it. You can play with the number of segments in the shell modifier to get sharper edges on the holes.
