Creating a perpendicular curve around a surface

Hello, 

I am new to grasshopper and only have a basic understanding of many of the functions. I am trying to create a perpendicular line off of a series of points that are around a surface.

I have the start points but do not know how to extrude/move them in a radial fashion around the surface. (Sort of like extending the Normal Vector but creating a new curve).

Help please.  

Image one shows the relevant part of the script. 


Image two shows the start points of the line that should be perpendicular to the surface.

Would you be able to rephrase your question and attach your file? I'm not sure what you're asking. Are you looking to create a line from the pyramids' apex to center of the base?
