Reply To: Cylinder flying off the curve
You set me on the right path, when i turn on cyclic it adds this additional line. that line is where 2 vertices overlap. I went back and remade the curve from the duplicated edge and that was a closed loop on its own but for some reason when converting it to a curve it doesnt become a closed loop.
It turns out that the loop made from the mirror modifier each quadrant had overlapping vertices when i converted it to a curve so i had to delete the overlapping point then fill the gap with fill and eventually i was able to complete the loop. Maybe just a nibble on the hat brim but thanks again for putting me on course
