Draw rectangles !

Hi all!

this seams to be an easy job to me but when i started, i faced some difficulties!

I have couple of lines in 2 different layers. first thing, i need to define the intersections of the lines in the grasshopper. then, having the intersection points, i need a rectangle on each point in a way that the point indicates the intersection point of the rectangle`s diameters.

first problem that i`ve faced, is while defining the intersection point of the 2 layers in grasshopper, it can find the points but 49 out of 50 of them are null!!.. why?!

Also, i need to know if there is any way that i can draw a rectangle in grasshopper by having its center ( intersections of diameters) ?

i`ve attached the files for your better understanding :)

any help would be really appreciated.

thanks

Hi Fernando,

Thank you so much for your reply, this is actually what i need except for that i need the intersection points to be in the center of the rectangles instead of the corners. ( as if they are the intersection of the diameters of the rectangles). would that be possible?

and other thing is i see you have selected the curves one by one, yes that works but the fact is that i need to run this definition for more than 1000 file! and that would not be possible!... thats why i tried to call the curves by their layers so that it can be readable in every other drawings..

Do you have any suggestions?

Again thank you for your great help.
