Convenient tool / method for creating "tabs" (NOT sheet metal)

This part is meant to be screwed into a wall so I need some "wings" or "flaps" to extend outward (from the highlighted edge).

The naive way would be just to create a new drawing on the face, [u]se the bottom edge, and then extrude and thicken it. Then repeat that whole process for the opposite side, or mirror the resulting part. I'd love to do this without having to create a drawing just so I can extrude an edge that is already defined in some other geometry. Is there such another clever way of accomplishing this?

    The only thing naive about your approach is creating a sketch, then surface, just to thicken...

    If you are making a solid, just stick to solid modeling techniques until they "can't" do what you need.

    That being said:
    select the face
    create a sketch (shift+s) 
    draw a rectangle (g)
    click one corner of the box
    click the opposite edge
    set a dim
    extrude (new) -> set length
    Mirror (Part) -> (Add)

    Or you could sketch on the Front face of the part (the long face in my example) and draw two squares and make them equal length on each end.

    There is absolutely nothing wrong with either approach. It seems like a lot of steps but, sketch/extrude is the bread and butter of solid modeling. It just becomes quicker with practice.

    For solid modeling, only use surfaces if they shape is "funky"... or you need some sort of re-usable geometry to reference many features.

    YOU SAID — Is there such another clever way of accomplishing this ?

    Here’s a way that’s more than twice as fast as using the Thin-feature extrude method

    steve_shubin  that is EXACTLY what I was looking for! Thank you

    > The screen capture is moving a bit fast and I'm not used to the mobile UI - in this example are you just creating a new sketch on the bottom face and then drawing a rectangle on it and extruding that? If so - are the two sketched "linked' in any way such that if the dimensions of the first sketch change (say the width of the box) then the second sketch will also scale its width (like when you Use an entity)?

    YOU ASKED — are you just creating a new sketch on the bottom face and then drawing a rectangle on it and extruding that?

    ANSWER IS YES


    YOU ALSO ASKED — If so - are the two sketches "linked' in any way such that if the dimensions of the first sketch change (say the width of the box), then the second sketch will also?

    AGAIN, YES


    Sketch 2 automatically added in constraints that linked it to the box (the extruded Sketch 1). Then as Sketch 2 was extruded, those flanges became one with the box as the extrusion defaulted to ADD.
