Hello everyone,

I have attached a file of a surface I created. I need to add thickness to it i.e. give it a volume. Thickness must be 2mm in the direction of the arrow. I tried doing this using offset-->shell but that didn't work. Not sure if that's the correct way to do it so I'm open to suggestions. Also if someone could explain why it didn't work that would be a great help as I don't see any errors in the file.

TIA.
