You've probably noticed the little folder with the stop watch in the top of your feature manager. But have you ever used it?
Sensors is an excellent tool that can be used on all parts and assemblies. A sensor can monitor Analyse data (from SOLIDWORKS Simulation), mass properties, dimensions, material, measurements and limitations.
Also the sensors can notify you if a certain demand is met. E.g. you're create a control cabinet that are only allowed to weigh 3 kg.
Try it out on your own construction or address the support to get more knowledge...
