Presenting a detailed CAD assembly of a steam engine modeled using SolidWorks Premium project focuses on demotrating the fundamental working of reciprocating steam engines through precise mechanical design and motion study. Key features include:Flywheel-driven crank mechanismSlider-crank piston assemblyTraparent housing for component visibilityFully cotrained assembly with motion simulationThis design emphasizes mechanical accuracy, design clarity, and assembly efficiency—serving as a solid foundation for both academic demotration and further functional to iights and cotructive feedback from the community.
