Trying to do a slot inside a frame

Okay so I have a very basic issue but i'm rather new to this software, I wish to do a frame, the sketch (lets assume is top plane) is as such: 2 rectangles one inside the other, the first extrude makes it all expand, lets say .05 the second extrude expands only the perimeter between the two, lets say .1, then I have a rectangle very thin - but halfway between the widths of the two rectangles which comprise the frame borders on the Front Plane.  I wish to subtract to a certain depth out of the middle of the model, however when I draw it on the front plane, it stays directly in the middle of the model and I cannot reposition it toward the edge or offset it (it only moves on the front plane) so I want to subtract so there is as slot visible on one side but not on the other - if I try a blind extrude it will only take 1 side out to the slot, but only starting from the middle, if I do it symmetric I will end up exposing both sides. Is there a simpler way to subtract a slot out of a frame or other object with only 1 extrude from an opening to a specified depth?

    Hi @andrew_kennedy !

    Glad you're trying out the software.  There are many ways to do this, but I think the best one for your case may be to just change the plane you're sketching on.

    By using the 'mid plane' option of the 'Plane' tool you can create a plane between the inner and outer wall of your frame, and then sketch on that plane.

    Then, your extrude operation will be simple:

    Feel free to copy this document to see how I did this:

    I've included another tab in the document called 'more complicated' that answers your question in a different way.  Instead of changing the sketch plane, I used the 'up-to-face' and 'offset distance' options in extrude to cut an outer slot from a sketch on the front plane.

    Thanks Jake, sorry for the late reply I will be sure to get back to you with my results, but I definitely understand!
