Flowline Elevation Lisp Request

I'm trying to make a flowline lisp but my lisp knowledge is below par. I tried making a dynamic block that does this with a formula and it does, except that when I change my ucs back to world and regenerate, it updates to the world elevation. Which is what I'm trying to avoid. Here, we do our plan views in world and our profiles in a named view. Is it even possible to write a lisp that recognizes the named view and can write the elevation based on the named view instead of world? I just want to be able to pick a point and it would automatically get the flowline (y value) of that point with a leader attached to it. Any help would be appreciated.

What represents the elevation on your profile drawing-is it a profile grid with labeled elevations? Does the UCS y value represent the elevation, but multiplied by some scale factor? I assume each "named view" has a different UCS per your comment about switching back to world.

Yes, I have a profile grid and labeled elevations from a mh block. Basically it's a mh block I put on the grid, where the rim is at the ground level and I have a leader that points to the bottom of the mh with the flow (in) & flow (out). I use 1:50 for the scale. And yes, the y does represent the elevations. Doing it manually, I use points for those elevations. I'd include a drawing but it's too big. I hope this makes sense.
