Hi @jsclage ,

>>>>>unfortunately the objects you are discussing are on the layer "rough openings"

Sorry for misunderstanding.

I thought you were talking about the "N Trellis" layer, as you wrote in previous posts.

If we talk about "rough openings" layer, there is another thing:

There is a hidden block definition in your drawing - _DetailCallout, which is visible in INSERT dialog:

This block has 2 attribute definitions. By default they should be on layer "0", but in your drawing they are on the layer  "rough openings" for some reason. Apparently someone edited this block in your drawing...

If you open this block in Block Editor and change the layer of attribute definitions in it to "0", you will be able to remove "rough openings" layer.
