Note : Elevation $46000$ and all dimention in $mm$ (milimeter)
The pipe will be installed on a surface of module structure, that module structure has different surface.
I want to know " ratio of the slope from point $A$ to point $B$ " and at the time of installation of the pipe, which points higher $A$ or $B$ ?
I am sorry if my explanation is hard to understand. I hope someone can help me to solve or give some hints for this problem. Thank you
