how to make the increase of dynamesh resolution work?

i created a dynamesh 32,
then i modifiled it
then i increased the resolution of this dynamesh to 100 in the menu of geometry, dynamesh,

but nothing changed,

do i need to press anything to make the increation of relusion work?

After you’ve just dynameshed, a subsequent dynamesh wont change anything until the mesh changes again. So either make some minor adjustment on the mesh (a slight stroke) and then dynamesh, or Ctrl-z back to before you dynameshed the first time and redo it with the desired rez.
