Extrude "boards" and maintain each segment?

john_trotto910

I am designing some drawers, which have bottoms, sides, back, etc.
When I goto extrude them, lets say the bottom and two sides, to the depth I want,
Onshape creates them as one U shaped part, not three separate "boards".
Is there a way to make it do this?
This would keep it looking right visually, plus make it easier for me to see and pull dimension off later.

Hey @john_trotto910 my recommendation would be to extrude the sides with a single feature (select individual faces in the extrude feature, rather than the sketch itself) and then use the bottom face for a separate feature. Alternatively, you could use side faces to split the 'U' into the sides and bottom.

An alternative approach may end up being even more helpful - draw the side profile and extrude. Mirror that body to create the second side. Now create a sketch that 'uses' the edges of the two side bodies and joins them. This way you can alter the design more easily and it will rebuild well.

@john_trotto910 There is a custom feature by Jake Rosenfeld called Extrude Separate. This will do what you are looking for.

On a similar note to @Jed_Yeiser: best practice would suggest a different approach. Consider Jed's technique or perhaps another way would be to have two separate sketches and extrudes. This way down stream features will know exactly which parts are extruded as the sides and which one is the bottom. Then you can boolean with the tolerances you need for fitting it all together. You want to avoid having all shapes in one sketch as this is not robust when you go to change the design later on.
