How am I able to dimension this complex solid body - can't pick edges on this Drawing?

Hello,

I am trying to dimension this complex piece of glass that is a complex curve made up of solid bodies.

I cannot pick the edges on the Drawing - such as the radii, the angled edges, nor some of the cut-outs to dimension the entire drawing like I would like to.

Could someone shed some light and help me so that I can make a detailed Drawing out of this model?

I am attaching what I have.  I did make some sections, and have a few sheets of this Drawing that I have made so far.

And help would be appreciated.

Thank you,

Barbara
