zbrush does not like tri's just quads
here is my problem when importing hex obj
if i use a hex polyline and draw some thing curvy
then fast extrude it and cap it by closing the top
the top piece need to have some vertical and horzinal lines evenly spaced apart like a grid
but when i draw the vertical and horzinal lines and come at then end of any curve i get Tri's

zbrush offers to substitute tri's when importing but it causes problem when subdividing
