Are there any unique features that make using SolidWorks on a laptop viable and efficient?

Sure! When you operate SolidWorks from a laptop, portability becomes a useful advantage. With laptop SolidWorks, you aren't bound by physical constraints to a specific workstation. This portability enables you to work on your designs from the comfort of your home, en route a road trip, or perhaps a coffee shop, essentially anywhere that suits your convenience. The performance level of your laptop dictates the software's functioning, but generally, laptops with powerful specifications can handle SolidWorks efficiently.
