well first of all you need to know all of the specifics in the problem, like if there is a given point in between the two endpoints of the upper and lower ( or side to side) lines to be the starting and finishing points of the ogee curve. PT A ------------------------

X given pt

-------------------- PT B

Turn on your DYN function ( F 12)
start a circle command using the 3p option
go to point A and choose this as your first point
go to X and choose this as your second point
then move the cursor back over Pt A to highlight it, this will give you a dotted line move in a -90 direction until you get the other dotted line from X.
This is your radius you should see it in your DYN read out.
Continue by multiplying the radius by 2 to get the diameter
Type this into the DYN read out and hit enter
You should have a circle that is tangent to point A and intersecting X
Repeat these steps with PT B instead of A.
Trim away the excess and the center where they both intersect at X will smoothly transition into a nice ogee curve

I hope this was explained well enough. Good luck and have fun.
