I have re-edited the message....
I'm trying to add an endcap to this part... and I can create asketch on the assembly but when I mate it I have to mate a top sideand a right side of the part which leaves the bottom part and theleft side of the part off in terms of the extruded holes... how canI draw in the assembly portion so that I can mate in plane fromthis part to the other part so I don't have to mate with faces, andrather with planes.. thanks in advance.SolidworksSheet Metal
