Can you explain this a bit more? Might be the after effects of the COVID/flu vaccine I got yesterday but I am not picking up what you mean.

Consider making a standoff: a hollow cylinder. You take a cylinder primitive and subtract a cylinder primitive with a smaller radius. If they have the same height, the top and bottom faces of the cylinders are exactly the same plane, which the Preview gives odd effects. The old recommendation is to name your subtracting cylinder taller and shift it down a little, so those faces don't share a plane. Manifold doesn't care.
Oh, maybe you mean attaching.
