Is there a way to identify the layer that is clicked on?

“Current layer” identifies the layer the user chooses as the current layer … is there a way to identify the layer that is clicked on?

By clicked on do you mean when you select a layer and it highlights light blue?

@michaelvollrath, Yes

How about this, it works with multiple at a time as well:

Graph Space:

Model Space:

__author__ = "Michael Vollrath"
__version__ = "2023.08.16"
#Made With <3 In Dallas, TX

ghenv.Component.Name = "Get Selected Layers"
ghenv.Component.NickName = "SL"
ghenv.Component.Description = "Gets the currently selected layer names from the Rhino Document"

ghenv.Component.Params.Input[0].Name ="Refresh"
ghenv.Component.Params.Input[0].NickName ="R"
ghenv.Component.Params.Input[0].Description ="Refresh Component"

ghenv.Component.Params.Output[0].Name ="Layer Names"
ghenv.Component.Params.Output[0].NickName ="Ln"
ghenv.Component.Params.Output[0].Description ="List Of Currently Highlighted Layers"

import Rhino

sel_layer_names = []

if R:
    layer_index = Rhino.RhinoDoc.ActiveDoc.Layers.GetSelected()
    for index in layer_index[1]:
        if index:
            sel_layer_name = Rhino.RhinoDoc.ActiveDoc.Layers[index].Name
            print("No layer selected.")

Ln = sel_layer_names

ghenv.Component.Message = str(len(sel_layer_names)) + " Selected" (5.8 KB)

@michaelvollrath Thank you … it appears to work once, but the refresh doesn’t work for me? Ideally, I’d like to work when the curve or curves are selected.

So the input R is a boolean value that when True re runs the script.

If you need it to update the script when an input change is detected from a referenced curve, that needs some different logic handling that.

And just to clarify, you want to get the selected layer not the referenced curves current layer? Correct?

@michaelvollrath When I click on the curve I want to identify the layer that that curve in on … using your terminology, I want “the referenced curves current layer” … sorry for any confusion, I appreciate your help!.

Ahhh, thank you for the clarification. That is a different script all together. One moment…


Here you are @MJD:

Graph Space:

import Rhino
import rhinoscriptsyntax as rs
import scriptcontext as sc

sc.doc = Rhino.RhinoDoc.ActiveDoc

layer_ids = []

for id in O:
    layer_id = rs.ObjectLayer(id)

Ln = layer_ids

sc.doc = ghdoc (5.2 KB)

FYI: In Rhino 8 WIP you can simple retrieve the layer information from the Model Object component.

@michaelvollrath Awesome…, thank you so Much!
