Combine two solids -> close surface

Rhino
1

Hi all,

I want to combine these two solids to create a compound object…
Boolean does not seem to work.

Is there a way to close the top surface of the box, so it matches the wave shaped solid?

Thanks!

Hello - DupEdge all the open edges and run PlanarSrf, then Join.
Hm - I guess that is not going to wiork if the circle comes exactly tangent to the linear edges - you’ll need to trim ‘by hand’
Cap the box, and then trim the top face with the circular edge.,
