Like in AutoCAD, does SolidWorks have a "dim break" command? If so, how does one break crossing dimension or leader lines?
Avoid it if at all possible. If you must, use the Break Lines checkbox on the Leaders tab of the Property Manager Page for the dimension:
As others have indicated, it can be done, however, that will only break around other dimensions. If you want an extension line to break around other annotations you'll need to drag the end of the extension line past the other entity, then insert a sketch line to simulate the rest.
