I have 3 kind of shapes, the “rectangle+arc” is ok , but the “rectangle+2 arcs no”, and the rectangle too.

My aim is to make a cross vault, for 3 different shapes, for the “rectangle+2 arcs” the solid intersection is not working and mention missing data,and for the rectangle even the arcs are not constructed…

You need to internalize your geometry.

thats part of the solution: it can’t work with missing data, which is due to a missing arc, so start there.

the red part is where a necessary line gets sorted out, being equal to a previous curve. getting rid of that whole part fixed a lot. now you can check why the vaults from the square won’t intersect
