Need some help,  I have a curtian wall in my model that won't delete. I placed it in the wrong spot. I can click on it, but It wont delete. It wont move and, on the properties panel everything is grayed out. It only shows up in an elevation view. Any help/

[#2]

Is it part of someone else's workset?

Some one helped me. They could not get the part to delet, but they used a filter and made it go away. Kind of weird.  Thanks

Doesn't really make sense...the filter will only "turn off" the curtain wall in that view.  Sounds like it still exists in your model.  Probably worth digging into a little further to see what the  problem is and how to actually delete the curtain wall. It may become an issue later.
