Visual LISP, AutoLISP and General Customization

I use to have a great lisp file that would draw a spot level (cross and level similar to the attached) once you picked a point on a 3D polyline. I think it was via a dcl window for the text height.

I can't for the life of me remember the name, has anyone come across such a routine?

thanks Jon

This ... ?

EDIT: code deleted

Thanks, but this didn't work.  It just gives a level of 0.000 on a 3d poly of 1-3 units high. 

the steps on the old lisp were . . .

1. Define drawing scale (setting the cross size and text height)

2. Pick a point along a 3d poly (or elevated poly) - not just the entire line

3. Cross and text is inserted at that point, showing the height of that exact point

thanks for having a look though

works fine if you use "nea" snap for the point. However the "point" X is not present for me.

And with a field?

Perhaps this:
