Modeling a domed surface on rectangular surface

Modeling a domed surface on rectangular surface

Modeling a domed surface on rectangular surface

(OP)
I am trying to create a convex dome on a rectangular surface. The problem is , as you'll see in the attached part, the surface makes a slight "dip" at the corners. How do I make the surface stay convex throughout?

I know it is geometrically possible, I have the actual part in front of me..

RE: Modeling a domed surface on rectangular surface

Edit the surface-loft. Under start/end constraints, change to Normal to Profile and the draft angle to maybe 20 deg? Reverse the angle to get what you want.
Play with angles and lengths.

Thanks for the tip, it was a step in the right direction but I still couldn't get quite what I wanted. This is probably a job for a more sophisticated surfacing program.
