Modern metal furniture frequently utilizes complex curves, tubular forms, and intricate latticework. Visualizing how tubular steel bends in three-dimensional space is mentally taxing without a digital 3D environment. Software allows for the manipulation of parametric shapes that would be impossible to visualize manually.
In SolidWorks or Fusion 360 , you sketch the side profile of the chair leg. You assign a "Structural Shape" (e.g., 25mm x 25mm x 2mm steel tube). The software generates the 3D tube geometry. metal furniture design software
