Break Smart BothKeyCreator \ Modify \ Break \ Break-Smart-Both
Location: Modify>Break>Smart Both
Compare this function with the Modify>Break>SmartSingle function. To understand the use of these two functions (SmartBoth and SmartSingle), it is helpful to compare them with Modify>Break>Both. With Modify>Break>Both, break is accomplished by selecting explicitly the two desired entities involved in the break. But with the smart functions, it is only necessary to select one entity. KeyCreator then automatically selects the second, intersecting, entity nearest to where you clicked on the first entity. So the location where you click on the first entity is crucial in determining which second entity KeyCreator selects automatically for the break operation.
SmartBoth does what SmartSingle does (break the selected entity to the intersection of its closest neighbor) and additionally it breaks the closest entity to that same intersection position as well. Note this special case: if both the selected entity and its closest neighbor are closed entities, the function defaults to a break single of the selected (closed) entity, looking for and breaking against two distinct points of intersection. It ignores breaking the closest entity.
Note that the SmartBoth function does not support selection of solid entities. (The SmartSingle function can break a solid that intersects wireframe geometry, not a solid that intersects another solid.)
