Thanks for the attachment. I remember a similar MathCAD file
It bothers me that you cannot open my 0.99.7610 SM files ...

you have 2 little mistakes
shape must be a string and you are passing it an integer
and second I think that in the functions you should use the assignment (: =)
and not the symbol (=)

Anyone have a good description, write-up, or web link that derives these two formulas? (Not Wikipedia)

Thats's nearly a prime example for using cases instead of if/else:

I've never heard of or used "cases"

Update, to add "IFs", Jean answered the question: click right hand most place holder, coma twice for one more if... again coma twice like before. Will be dissecting this function. Thanks to others who posted sheets.

Hi. You don't need to divide by the units in the body of the procedure. Notice that z is the side slope, so it's dimensionless, equal to length / length, even eventually can have units, like mm/m. This is, given that z is the horizontal change per unit vertical change, it's usual to use one unit for horizontal change but another to the vertical change.

Best regards.
