hey, I'm trying to create a logo and i cant figure out how to make it a single object, I've joined and overlapped vectors, used all combine tools (unite, subtract, unite at overlap and subtract at overlap), tried to do an offset at 0 or .21 which is my kerf and it creates random vector lines to close the object even after i have closed the ends off, usually pretty good at working this stuff out, i may be over looking something, file attached in order left to right, original piece, closed ends, combined/united.

 i need to set kerf on these cuts but unless the object is one it wont allow.

thanks.
