1. I started off by drawing a cube as a guide for my circles. I was thinking of lofting the curves to create the Batwing surface. Later I was stuck as to how to actually create the pattern.
2. I was really stuck as to how to create this surface so I googled, 'how to create a batwing surface with Rhino' and BINGO!!! I found this link that teaches me step by step how to create it: http://www.jotero.com/bilder/moi/batwing/
3. The video tut doesn't actually tell me the measurements or angle of the curves to create, so I just guessed, judging from the video.
4. After creating the most important surface, I mirrored it AND....IT DIDN'T JOIN!!! As you can see, there's a hole in the middle!!!
5. It took me a while to figure out how to do it. After leaving it for a few days, I finally figured it out! I set a screen print jpg of the desired form as a background in Rhino and copied it from there.
6. As you can see here my purple surface doesn't fit within the surface of the tut image.
7. I created the surface from the 4 curves using 'NetworkSrf'. I matched the surface pretty closely to the tut's surface so I was happy!
8. Once I've created the base surface, I had to mirror it as follow.
9. BINGOOOO!!!!! I FINALLY DID IT!!!! IT MIRRORED PERFECTLY!!!!!
10. I'm so happy with this that I just gotta show another image of my prized success!!!
11. I'm so happy that I was able to achieve this Batwing surface that I'm gona show every single step I did from here onwards!
