This question is asked fairly frequently. To help get the word out about existing SolidWorks functionality, here's a republished article that originally appears on SolidWorks Legion as How to match up projected projected Break view with its parent view's break.
Break views are common practice for some industries where long components do not fit well on standard sheet sizes at a useful scale. SolidWorks has a function to break views in the Break tool in the Drawing toolbar. However, what if there is a projected view of that component which must also have a break? Do the breaks in each view automatically track with each other (match up or align)?
Yes. As with many abilities in SolidWorks, there's a setting that controls this. This setting allows you to determine if you want the projected view to always match up with the breaks in the parent view. This choice is important, as there may be a very real purpose to not align breaks between views. For example, the parent and projected views may show details at different locations along the length of the component.
However, if the user wishes the parent and projected views to break at the same locations, the setting is located for the projected view in its PropertyManager>More Properties... button>Align Breaks with Parent check box.
