Cannot figure out how to delete a selected set

[jforri20]

I have been polymodleing with the 3 orthographic views and image planes. I'm trying to keep my work space as clean as possible but I keep having these selected sets pop up and I cant get rid of them. I started a brand new scene and created a simple cube, then added extra subdivisions and an image plane. Finally I selected the Image Plane and the top faces of the cube and isolated them. Now I have a new set called "modelPanel4ViewSelectedSet" and there are copies of the object and the image plane inside, but i cannot delete it even after taking out the copies (they vanish into thin air when pulled out). When I try I get: "//Error: file: C:/Progr.../doDelete.mel line 111: Non-deletable node 'modelPanel4ViewSelectedSet' cannot be deleted."

I'm sure there is a simple solution, I have little education with Maya and it's mostly self taught so if someone knows what is going on and what these sets are I would appreciate it greatly. I have never posted on the forum as most of the issues I run into I can find help with but cant find any on this topic and I just lost a days work of modeling so here I am lol.

Hey @jforri20,

The set which is created during 'isolate select' is Non-deletable node. When you come out from your isolation mode automatically the set will be gone.

The set is useful for having a selection of something(like meshes, faces etc.). These manually created sets you can edit.

thanks for this. I also had this question.

Yeah Mine is always there. It creates a new one when I go into isolate selection mode. How do I get rid of it? Also, LightEditorRoot, thats new right? Cluttering up my outliner...

不知道你是否解决了这个问题，我今天遇到了同样的情况，这个帖子好像还没有答案，为防万一我把我的代码留在这里给再遇到这个问题的人一些帮助，使用之前请保存文件
