Hello Everybody!

I've attached the file and am trying to figure out how to extrude a sketch at an angle, instead of straight down.  Ive cut a parabola in half and I need to extrude from the  point of the parabola, down to the square excrusion...and I dont know how to do it.  Also, I need to mate the two sketches (sketch 10 &18 together) I tried a midpoint to midpoint coincident relation, but that didnt work.

Thanks for all the help

Charles
