I have a somewhat newbie question. See attached doc for my attempt to help explain. I have to align this part to BCD. -B- is a plane in 0,-1,0 (facing me). -C- and -D- are counterbores of thru holes. So I level -B- to Y- and set -B- as my Y origin. I'm stuck after this. I don't know how to rotate -C-. Or even what my rotation should be. I want the part facing the same direction I have it in (Y-) when I align it to BCD. Can I create a line from -C- to -D- and rotate that about Y-? Or is that "illegal" from a GD&T standpoint (meaning should only -C- be rotated and not a -C- / -D- line?) If I can make a -C- / -D- line do I have to trig it out to get the angle to rotate. I'm baffled to be honest. I appreciate any help any one can offer. Thanks so much.
