I am new at Toon Boom Studi, I just started at two days ago.
(I asked for a few tutorials at a time ago, but I just read it now, because of my college work)
I have experience in Flash but I decided to move on and try something more professional.
I saw a couple of tutorials and I am learning fast. But I can’t find the option to create a Symbol like in Flash, I saw a tutorial form Toon Boom Animate and I saw that this option also exists in TBA but I can’t find any option to create a Symbol in TBS.
Does that option exists to TBS as well?
Thank you for the help 
Toon Boom Studio does not use symbols but Animate and Animate Pro do.
You can always cross-grade from TBS to Animate or Animate Pro if you wish to take advantage of that feature and especially if you have a Flash background.
