Lip extrusion on tutorial file

I am a solidworks newbie. I cant get it to extrude the lip on the tutorial
(the getting started manual.) What I do get is an extended lip on the outer
surface, ie an extension of the box part that I am trying to put the lip
inside of. It doesnt seem to want to select the section that I have offset,
only the lip that its attached to. Also are there any good newbie resources
out there for solidworks?

Mike,

There are 2 steps to making the lip in the sketch. My guess is you
only have one loop and you need two loops.

The first one is created from Convert Entities. Convert Entities
extracts the outside edge to the current sketch plane. You should see
one loop.

The second curve is utilized with the Offset Entites sketch tool, with
the first loop selected, enter the offset value and be certain the
offset direction is to the inside.

You know have 2 loops.

These loops become your extruded cut. Make certain the direction of
the cut is into the material of the part and not off in space.
