Exclude grass with projected mesh

Hi Guys! Is there any way to exclude the generated grass with projected mesh?
The problem with the “apron” that it creates hard edges, you cannot create a
curve. Thanks!

Hello @tsgucci , This is not possible with a projected mesh but when using an
apron, you can select few points and use Transform to spline function to make
it smoother: Before :

After :
Hope it helps. Regards, Boris
