First thing we should do we need to create some text that we want it to be look like 3D.. and of course choose the font you like.. i used Dark crystal script for the font..

Next i change some other detail of the font by adding some swirl line design to make it looks unique or let say to put some attitude by it just the word itself “animal”

Note: to edit or modify live font we need to expand the font by selecting the font and press Ctrl+Shift+O or select “Object” on menu bar then select “Expand” leave object and fill checked then press “OK” in this mode you can edit/delete some anchor point of the font and also remember you cant edit the word anymore after you expand. see sample image..

heres the cool part after your done designing.. lets apply the 3d look effect..
select your design/object, copy and paste then change the color of the original object in any color you want also also with the copy object.. i choosed light gray and black:

decrease the size of the 2nd copy by 2 times or any size you want.. make sure the 1st object is in first in layer to make sure select the 1st object and press Ctrl + Shift + ] then place the 2nd object in back of the 1st or any direction you feel to make it look the best..

and the finale select your two object goto Object>Blend>Blending Options.. i used the setting below..but you can always play with your desired..

after pressing “OK” and the two object selected press Ctrl + Alt + B.. and viola!!!
a simple 3d look render in illustrator.. you can use that technique in so many way see image below.. i add some white stroke and change the light gray to orange..

and here's my final result..

have a good day! -_-
