font what you use, Ai file that you sent cannot be opened

The font is vector and I don't know the name... no one here does... if you can't open the .ai file, I don't know what to tell you. You tell me what format you want and I'll deliver it :)

Hi can i show you some new 3D designs?

The rules are no "new" designs. You have to make 3D interpretations out of the current logo. It's clearly stated in the brief. It's not my decision, it's their decision.
