The tutorial continues the staircase design process in SOLIDWORKS, focusing on global variables, construction geometry, and multi-body modelling. It demonstrates creating rebates for steps, risers, and wedges, then using linear patterns linked to global variables for automation. The video covers applying materials and textures, adjusting wood grain direction, and mirroring components to build the staircase efficiently. It explains managing dimensions through equations for flexibility and adding steps and risers with controlled references. Finally, it showcases finishing touches with satin oak textures, ensuring consistent scale and orientation, resulting in a fully parametric, visually accurate staircase model.
