Boolean union fails no doubt co planar but how to fix?

Rhino Rhino for Windows

Hi,
V5.
Boolean Union fails, no doubt the shared surface top and bottom.

However I try Boolean difference to cut them (the solid going into the solid) off and that fails, there again that would then fail as it would give new shared surfaces.

There will be many times two items are of same height and intersect, that Rhino dislikes one being same height as the other is very …lost for words !

I thought this with one solid going into the other would union.
I try explode then use cone wall surface to cut them, that fails.

Just how can I solve this ?

Hi Steve - this works fine in V7. If you are working in an earlier version where it does not work, just Intersect, split and/or trim, as you’d expect.
