How do i create a solid 3d shallow elliptical dome

How do i create a solid 3D shallow elliptical dome? 

I need it to be 103mm x 75mm  and 3mm high.

I've tried scaling a block but cannot explode the reference block. I've tried creating a domed surface but i cannot convert it to a sold.

Please help 🙂

Something like the attached one?

... and >>here<< a video. 

BTW: This has nothing to do with Dynamic Blocks.

See >>here<<. 

@john.vellek's answer #6 (and the limitation) is still relevant.

Thats spot on cheers, how did you do it?

First you need some ellipses - one ellipse 103 x 75 and four elliptical arcs 75 x 6 and 103 x 6 (twice each). 

Then create a loft using the elliptical arcs as cross sections and the full ellipse as guide. 

Convert the resulting surface into solid and slice the half. >>Done<<.

... before you ask how to draw the ellipses - >>here<< one example. There are a lot of other possibilities too.
