Select object by layer, delete, and...

Hi, I'm trying to make some operation with objects and layers.

I have succefully created a C# script that can create a list of layers with given name and bake given objects on the first layer of the current rhino document; I also have the list of layerIndexes for the given layers.

What I'm trying to do next is to select these objects and test some conditions from other data:

for the objects that have the same referenced value as the target value, do nothing, leave them in their current layer;

for the objects that have an higher referenced value than the target value, select these object and put them in the next layer (a sort of: current Objects' Layer IN current layerIndexID+1 );

for the objects that have an lower referenced value than the target value, select these object and put them in the previous layer (a sort of: current Objects' Layer IN current layerIndexID-1 ).

With this

Rhino.DocObjects.RhinoObject[] srf;

srf = doc.Objects.FindByLayer(layerName[0]);

List<Rhino.DocObjects.RhinoObject> srfs = new

List<Rhino.DocObjects.RhinoObject>();

foreach(Rhino.DocObjects.RhinoObject obj in srf)

{

obj.Select(true);

srfs.Add(obj);

}

A = srfs;

I get Rhino.DocObjects.BrepObject but they are nothing, I don't really select them.

I also tryed to translate this C# code http://wiki.mcneel.com/developer/sdksamples/sellayer but there are things I can't find in the RhinoCommon, like lookUpObjects or MRhinoObject, m_doc(I thought it was a variable but I can't see the declaration).

Thank you, bye.

Andrea

I made a little piece of the code working.



List <int < srfs = new Listi <int <();

System.Collections.Generic.List < Guid < ids = new System.Collections.Generic.List <Guid<();

foreach(Rhino.DocObjects.RhinoObject obj in srf)

{

//obj.Select(true); //select objects in the layer

ids.Add(obj.Id);

}

if(del == true) //bool input

{

for(int i = 0; i < ids.Count; i++)

{

doc.Objects.Delete(ids[i], false);

}

} else

return;

This part retrieve the Guid of selected objects on a layer (srf is the list of object in layer) and delete them. It was so simple...

What do you mean by "referenced value"?

Ok, i'll try to make it simple. I know that "referenced value" is the wrong name, referenced is totally another thing. Maybe it was better saying external value.
I have a list of points. Each point has a value associated from another list. I have a list of surfaces above these points. I made some scripted components that tell me wich points are affected by each panel and perform the mean value on the associated values. Depending on this mean value (external value) and a target value I have to choose in which layer I have to bake each panel (I have 5 or 6 different layer). At the moment I'm working with 76 panels, but in the near future I have to work with thousands of panels.
I get this values from daylight simulation in Radiance and the layers are the radiance material that I have to apply to the panels, so this process will be repeated n times.

It's quite difficult to explain in words, I know.
Bye

Sorry, still don't get it. Is the following correct:

You have a list of points {P}. And you have a list of values {V} (numbers?). These two lists are the same length, and the point at P[i] is 'linked' to the value at V[i].

You also have a list of panels {S} (Surfaces of Breps I assume), but I'm not sure how this ties into it.

Then you have a "target value" (single number? a list of numbers?).

In your bake operation, you want to see if the value in {V} is less than or greater than the target value and bake (the points?, the panels?) to a different layer accordingly.

Am I correct so far?

Exactly. The list of points and the list of values are the same length. List of values are rounded doubles. I have a mean of the values that are linked to the points that are exactly under each panel. I created a branch for each panel that has as items the values that are linked to the points.

The panels are rectangular surfaces. They are above the points.

The target value is a single number, a slider.
