We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

But why should a self-intersection occur if I have changed the geometry absolutely nothing? I have only added 2 angles in SpaceClaim, but have not changed them. The sphere is still 100% in the same position, so the angles are both 0°. So how can this error occur without changing the geometry, just by naming two angles? 
 
But apart from that, in the parameter study, which I have not yet carried out, these 2 angles are supposed to change (i.e. the sphere is supposed to rotate). How is this possible without the error of self-intersection?
