making a pattern 1.5 wide 14.0 long with an S curve in it. Want to make several of these cut outs, some now some later. Want to cut these out with a .125 cut bit. after I save the pattern and bring it back on a board, the bit I assigned to it when pattern was made defaults back to 1/16 carving bit ,and cannot get the select bit icon to light up so it can be changed to .125 cut bit again? What am I doing wrong????
