Hi Rob,

I drew the shape in v20 and it worked. I just used Geometry and the way I would draw it if I was still at the old drawing board.

Put a point on the X axis where you want the two .250 Arcs and draw the arcs. Then go to the Arc menu and select a 15.75 arc. Snap a 15.75 radius from each of these two points and put a point where these two arcs intersect at + Y and - Y. Then change your radius to 16 and snap a radius from each of the last two points. These last two radii will be tangent to the .250 radii. All you have to do then is trim off what you do not want.

Hope this helps,
