I see what you mean... but unfortunetly i need it to be on top (map design, reasons)

I guess the only way i have is to make the top using several brushes just like the one showing in the screenshot editing one by one and moving the vertices around a liltle. I already noticed is kinda limited. You can't add vertices, but you can cut a border in a regular brush (4 edges) so you can get 2 vertices where there was just one....(5 vertices) every time you want to get all the vertices you want, but the movement of the new vertices is limited....
Thanks... ill try that...
I have to do another hole in another end cap i made (180ยบ)... Its just in the middle of the curve, so I guess ill be able to use 2 semi cuves with a normal brush in the middle
