diagrid tower angle control

All,

I'm trying to generate a diagrid tower with grasshopper, but control the angle of the 'crosses' and the amount of lines on the surface. 

With a simple cylinder i could use a spiral to generate these crosses, but if the surface is non regular this is becomming very hard. 

just to provide an image, this is what it should look like, but with controlling the angle and not a cylinder...

Hope anyone understand what i'm looking for and knows the answer or has pointers in the right direction.

Thanks, 

Tijl
