I took the end of a scupty and made and inside wall so i have empty container. I want to shape the outside and inside wall but when I use
the loop command with the select edge I only get the wall that I have slected and not the inside one. Is there a short cut key that will get both of them or do I have to select them both before using the loop command?

Thanks

Use transparency and “show back faces”.

Then you select an edge on the inner shell and the outer shell, and then do the loop.
