That was what I needed. I figured out the top radius part, but I was having trouble with the changing height when I changed the top radius. I wanted to keep the angle at 45 deg. So I decreased the height of cut by 1 mm and voila, I had the 1 mm radius and the height stayed the same, therefore so did the angle. I then just did an Edit Content in the part tree and put a 1mm radius fillet on it.
The problem with re-doing the 3D solid was that the feature is so buried in the part tree that I was scared to try that. It might be a simple task for some, but I didn't want to have to de-construct my model to replace the cone.
Thanks for the assistance,
