Shapr3D: CAD + 3D modeling on Instagram: "Parametric robotic arm controlled entirely through sketches 🦾 This tutorial shows how to build a robotic arm where every angle, position, and movement updates from sketch changes. Modify one dimension and the entire assembly follows. Use driving sketches, construction planes, and variables to maintain geometry relationships. Change the base rotation sketch, and all connected segments update automatically. Link to the full tutorial in bio ⬆️ #Shap
