Trim tool too unsmooth
 

Hi i have a problem trim doesn't work well whats my problem??
Just look at the attached picture

someone got an idea??

Are you using the text tool to create the letter?

yes

chances are likely that it's just a display problem - trimmed text usually looks crappy like that... try a render, see how it looks. it should look fine.

thx it works

You can call up the attribute editor and increase the display tessellation, as well, though this will slow things down if you increase it too much. The render is what matters.
