Very basic swift 3d problems

dear all,
i am a new user of swift 3d & was wondering if anyone would be able to answer a couple of queries i have re using it.

first problem is that i have published a page with a logo produced in swift 3d @ www.iconsportsmanagement.com/3dlogopage.htm. the logo is ok but i need to slow the rotation down without making it appear ‘jerky’ or inserting additional frames which would increase the file size (i think). is there another way of ding this.

also i am trying to recreate the logo with the small text underneath removed. when i amend this in illustrator & import into swift the circles in the logo becomes hexagonal & the word icon becomes blocky as well. cant understand this because all i’m doing is removing that bit of text at the bottom.

thanks in advance for you help
paul
