I’ve been making an ear’ole on the babys hat to let the sound in. Bless him! It needs some screw holes to hold it on, and i’m getting to them! Here is an instructional jpeg on how I built it. OMG!

Here, we see a NURBS surface, scaled to the shape I want the ear piece to be. In the second pic, amazing shapes are drawn over the sphere in an orthagonal view.

Now see! The magic! Loft the crazy curve shape through the sphere and intersect the surfaces to create curves on the actual surface of the sphere! Then use the awesome offset curve on surface tool to create outlines bigger and smaller than the original shape. Whhoooo there! What are they? They are our guides for our bevels and no less! Now, convert the original NURBS to polys and use the old NURBS sphere as a LIVE surface to draw all the nice vents on. Now bevel the nessecary edges and BBOOOP! We have a lovely perfect poly surface which will smooth down a treat should we need it to look smooth like a butter square.

Well that was utter bollocks. Hope you don’t try to do this, cause it’s late, my girlfriends waiting for me, and that all made no sence. They call me the professor…….. Get your specs on.
