URGENT!!! brick extrusion according to a surface using srf cp

Hi,

Im so glad we have a website where people really help each other.

Im coming across a problem, Im making a brick facade and i want to extrude a set of planes(bricks) according to distance from a surface.

iv made a grasshopper def that is theoretically correct but it isn't executing...

on extrusion it only extrudes some of the brick planes but not all.

If i put a panel to check the output from D (distance between point and closest point on surf) of srf cp, many items come out as null!!

please help asap! i have a submission and im freaking out!!

this is the surface i used in srf cp

these are the planes i want to b extruded according to distance from surface

these are all the extruded rectangles i get!!

Ps- the problem is not with the surface being too low, it is not. and i have tried it with different surface with more hieght too.

No clear your doubt, if you upload your. gh will be easier to help ...

If you have points on a surface, why need the cpsurf if the distance will be 0?

Is this what you wanted?

thanku for the reply!! :)

i need exactly that! bricks extruded 9" from the top and goes down to 4.5 at the other end ( actually i want it a little more complex than that so i used a surface and srf cp as a parameter for extrusion heights ... i cant open your file as my grasshopper is of an older version..

ill attach the file iv made can u see whats wrong? please and thankyou!
