hello again,

Is there a simpler way to have a short formula?

=IF(A6=A3,B3,IF(A6<A2,(A6-A1)*C1+B1,IF(A6<A4,B3+(MAX(SQRT(D3^2-IF(A6<A4,A6-A3,0)^2)*(IF(A6<A4,A6-A3,0)<0),SQRT(D3^2-IF(A6<A3,A3-A6,0)^2)*(IF(A6<A3,A3-A6,0)<0))-D3),IF(A6<A5,(A6-A4)*C4+B4,"XXX"))))

this is a line+circ.curve+line equation to get elevation...I hope i can
simplify this for easy remembering..

Tell us what the math is (not the Excel)

You will need to describe what is stored in the various cells you are
testing against (for example, A2, A3, A4, etc.).

I would like to ask a question though. I see you mentioned Line-Arc-Line to
get an elevation... I was a Civil Engineer in Road Design for some 32+ years
this *almost* sounds like a roadway elevation calculation **except** that
roadway elevations are almost exclusively calculated with a parabolic arc
between tangent lines, not a circular arc. Can you confirm what this
calculation is being used for?

Exactly, line-circ.curve-line...
I'm trying to contain all the levels on one calculator-formula based on
assigned
Radius, Lc,gradient slope of lines & chainage of Pts. .
the formula looks long for me to remember.
Do you have a simpler sinlge formula.
Thanks for the reply.
