Elliptical Dome

[jfixsen]

I'm trying to make an elliptical dome that is 5.38 long,4.38 wide, and 1.25 tall. It has a radius of 4.50 the long way and a radius of 2.88 the short way. The outside edge is vertical. I'm trying to model 1/4 of the top and then I'll mirror it two ways. I have a sketch that is the elliptical outside edge as the trajectory and then I sketch the two cross sections that are 90

Hi jfixsen,


Just setup a couple of datum curves then build a Boundary Blend, just your second radii 2.88...it is tru or not?

I looked at the model, it has a strange asymmetrical behavior if you check surface curvature, I think the reason is because you use only two curves and the entire ellipse... I think it's better to use 4 curves (mirroring the two you already drew) and let the boundary blend use all of them
