For me Achieving clean illustrations , illustrator works fine i love it , i love its tools and i love having the liberty to modify my line art with powers of illustrator. But i sometimes have felt and used flash as a successful tool for vectorized art . I will share with you here how you can use flash and illustrator to create cleaner illustrations . I chose to create a geometrical yet simple object ie a castle to vectoriz here . I used flash to create the basic line work and then painted it in adobe illustrator using paint bucket. tool.
