Many thanks,

What are you looking to do with this? Boolean it together, make it out of sheet metal, prep it for machining?

CNC the parts out of bamboo plywood, glue it together then round off the edges with a router. I could just keep them sharp on the CAD model but I'd rather know how to do it.

@bart Take a look at sketch1, sketch 2, and sweep1 here:  https://cad.onshape.com/documents/1e8ca355dee37a2a10b052ba/w/943fb91c81782e3af501e738/e/993f6cb4ce1f3e871a865f85

You can adjust the profile on sketch 2 for your specific router bit.

Hi Pete, thanks for your answer!

Although I am actually doing a convex fillet all round, and down each side, your use of the sweep tool has made me realise that it can go around corners! 

Here's my amendment.

I guess I just need to do the same at the sides now with four separate sweep commands. Can you think of a better solution?

Thanks again,
Bart

@bart Yes, a sweep remove at each side/corner.  Make sure to check "Keep profile orientation" on the sweep remove.
