Expected behavior
When constructing enclosure over assembly part using the same dimensions as assembly part there should be no fit errors.
Actual behavior
Assembly is reporting fit problem of the enclosure using tangent arcs at the corners, despite tangent arcs have exactly same dimensions. It is very likely some numerical issue.
