SURFACE POPULATING + OPEN & CLOSED COMPONENTS _

Hello people!

I am having some trouble with two specific Grasshopper [ 06.0019] definitions at the moment... I would appreciate any feedback or - even better - any kind assistance...

The first one is the "Surface Populating" definition: I manage to populate my geometry over the surface, but after I bake it, I have to delete the boxes that define my components limits as well! Is there any way of populating and baking only the chosen component, without having to delete the boxes afterwards?

Secondly:

Basically: I am trying to cover a surface with two types of components [ an open one and a closed one] , which will be proliferated over my tubular surface according to the main sunlight direction.

1. I introduce the surface component.
2. I use "Divide Interval2" in order to have division into U and V.
3. i generate the target boxes [ "surfaceBox"] .
4. I use "Isotrim" ( same intervals) and "BRepArea" to find centroid of each area.
5. My "Curve" component introduces sun angle, with its "End Points".
6. I use "Vector 2Pt" to specify sun-light direction.
7. I want to measure the angle between sun-light and the surface normals, at the position of each component; after generating the centre points, I need the normals of each centre point to get the surface's points' UV, and "Evaluate" the srf at points.
8."Angle" and "Vector" components: I use them in order to evaluate the angle between the sun direction and the srf.
9. I convert this angle to degree by using a "Function" [ to see if the angle is bigger from the max.angle or not...]
10. Function "x,y" gives me boolean data.
11. Data become "Dispatch"ed...
12. Two "Morph" components , each one linked to one part of the "Dispatch" data, generate "closed" and "open" components over the srf.

The result should have been different types of components, based on the surface's curvature, diraction and sun-light direction...

I do not understand where the mistake is in this definition...

Thx in advance1
