I know "we" solved this problem years ago, but I've forgotten the solution.

I have an object that I am reorienting from y to -y.  At the .y=0
transition, there is a flip.  

I see how Mike Williams did it in sweepmesh, but for practicality in my case
I would like a single transform.  Is there no simple mathematical
transformation that allows this to happen without the flip?

I'm not sure what you mean by "reorienting from y to -y without flip".
A rotation by 180 degrees might be what you are looking for.

Hmm, y to -y but no flip?  Like scale y by -1 so it's reversed, and then
translate it back to the same position?    You can always put
multiple/sequential transformations into a single transform{} variable.
