Go Solo (aka Isolate Selection) without zooming on the object

Coding Python Support

Hey guys, I could really use some help on a script …
Well, actually it is not “help” but more someone who can code this for me :o

I would like to have a toggle script that moves the selected objects to an empty layer and activates that layer.
If I execute the script again the objects should be moved back to the original layer.

Do you guys think this is possible at all?

Cheers Christian

Awesome, works perfectly :slight_smile:
Many many thanks for the quick help!!

I was trying to make a .py script out of that to be able to assign a hotkey to it and wrote the following.
Unfortunately I get an error message when trying to activate the script in the addons menu.
Does anyone know how to make this work correctly?

Cheers Christian


bl_info = {
    "name": "IsolateSelection",
    "category": "Mesh",
}


import bpy


class isolate(bpy.types.Operator):  
    bl_idname = "object.isolate"  
    bl_label = "Isolate Selection"
    bl_options = {'REGISTER', 'UNDO'} 


    lay20 = [False,False,False,False,False,False,False,False,False,False,False,False,False,False,False,False,False,False,False,True]


    sc_status = bpy.context.scene.get('iso')
    if sc_status == 0 or sc_status == None:
        bpy.context.scene["iso"]=1
        bpy.context.scene["old_lay"]=bpy.context.scene.layers
        for i in bpy.context.selected_objects:
            i["old_lay"]=i.layers
            i.layers = lay20
            bpy.context.scene.layers = lay20
    elif sc_status == 1:

        bpy.context.scene["iso"]=0

If anyone has an idea why this is not working please let me know.

Running the script the first time to register it requires some extra sanitation with running code and context. Here is the corrected code.

bl_info = {    "name": "IsolateSelection",
    "category": "Mesh",
}




import bpy




def main(context):
    
    lay20 = [False,False,False,False,False,False,False,False,False,False,False,False,False,False,False,False,False,False,False,True]




    sc_status = bpy.context.scene.get('iso')
    if sc_status == 0 or sc_status == None:
        bpy.context.scene["iso"]=1
        bpy.context.scene["old_lay"]=bpy.context.scene.layers
        for i in bpy.context.selected_objects:
            i["old_lay"]=i.layers
            i.layers = lay20
            bpy.context.scene.layers = lay20
    elif sc_status == 1:
        for i in bpy.data.objects:
            ol_tag = i.get('old_lay')
            if ol_tag != None:
                old_lay = []
                for j in i['old_lay']:
                    if j == 0:old_lay.append(False)
                    else:old_lay.append(True)
                i.layers = old_lay
        old_lay = []
        for j in bpy.context.scene['old_lay']:
            if j == 0:old_lay.append(False)
            else:old_lay.append(True)
        bpy.context.scene.layers = old_lay
        bpy.context.scene["iso"]=0


    


class isolate(bpy.types.Operator):  
    bl_idname = "object.isolate"  
    bl_label = "Isolate Selection"
    bl_options = {'REGISTER', 'UNDO'} 


    def execute(self,context):
        main(context)
        return {'FINISHED'}




def register():

thank you so much for the help! its a lot better like this :smiley:
