Can this be made easily in MOI?

Well you can alwayds sweep a profile and a curve to create de bar, and then use the array along curve for the half tubes.

But it's far to be perfect !

Btw, I don't know if it comes from my computer, but revolve tool is extremely slow (nearly impossible to create the revolve axis)
