You can selectively find differences in the front panel and block diagram of a VI when comparing VIs or VI hierarchies. For the block diagram, you can choose to ignore cosmetic differences. A cosmetic change is any change that does not affect the execution of the block diagram. Furthermore, you can choose to ignore the position and size changes in front panel and block diagram objects. Position and size changes include movement of an object from front to back and vice versa.
You can also identify differences in VI attributes, such as settings in VI Setup.
Refer to Show Differences for more information on selectively finding differences in the front panel and block diagram of your VI.
