This video highlights how SOLIDWORKS was essential in designing a portable cocktail bar within a strict weight limit of 3.5 tons, the legal towing maximum for lightweight structures. By applying accurate material properties and predicting component weights before construction, the team ensured compliance without guesswork. When the finished structure was weighed, it came in at 3.4 tons—precisely as planned—demonstrating the reliability of SOLIDWORKS for mass prediction and material management in real-world projects.
