Trying to Draw a Rectangular Block with 2 Grooves on One Side That are Both Diagonal to the Object

I have only used Onshape a few times for some very simple shapes with over a year between uses. I know and remember very little and just plain don't know much. I’ve been working at this for awhile now and haven’t figured out how to do it yet, but may be able to describe what I’m trying to do.

What I want is a rectangular block that will have two round bottomed,straight sided grooves on one side. They will run diagonally so that on one end they will be farther apart than the other.

I can create an object with the groove of that shape I want by sketching a circle with squares on either side of the it and extruding the block to the height of the squares. To do this I have just used in the center point of the three planes and I only have one groove and it is perpendicular to the object.

To actually do what I want to di it looks like I can add working planes to create at working plane of each end of each line. I think I would use the point plane type to do this, but am missing something as I don’t see any such plane appearing and it doesn’t make a groove.

I noticed that after I extruded to make a 3D object, my lines and sketches disappeared, but did figure out how to make them visible.

Maybe I’m going about this the wrong way or something. Maybe some can clue me in a little.

Thanks in advance.
