Simple Empty Box Component or Object : How to ?

[cmoher3]

I just want to draw an empty box with a bottom and no top. I tried using Model >> Sketch >> Rectangle, then extruding to a 3D object. Switching to Patch mode I then clicked on the upper plane and hit delete, followed by a Thicken operation to build up the walls. Unfortunately, I ended up with a box that had neither a top nor bottom. Rather a squarish sleeve.

not exactly sure what you mean by "an empty box with a bottom and no top", but if it's this (a solid box with a uniform thickness), you should use Shell on your solid block, and select the top face as the face to remove:

Sorry, but I don't see SHELL in my Model or Patch menus.

should be under the Modify section:

If it is not there, right click in the toolbar and choose "Reset all toolbar customization":
