Now arrange for the total length of the merged curve to be 20km

Do not delete your question, ever!

That violates the principles by which this site was founded. :mad:

I'm attempting a similar problem -- would you be able to expand upon that? I'm having problems manipulating my cubic function(s) to fit accordingly (namely, setting local max/mins and getting them to lie between two points).

Also, those two cubic function would only cover the first 'part' of the 'profile', and not the final slope downwards -- how would you go about that?

Many thanks,
