Remove Intersections will remove any points at the junction of three or more edges. This is not strictly necessary to perform during Sim Clean as it can also be done when using ‘Edge-2-Bone’. However, it is available here and enabled by default to act as a edge/bone preview.

<aside> ☠️ Intersections must be removed, either here or later during bone creation, otherwise it is impossible to determine correct bone chains and directions. However, if wished, you can disable ‘Remove Intersections’ during both Sim Clean and Edge-2-Bone but the results will not be clean.
