I already have the product as a .STEP file and now need the matching aluminum mold form engineered around it. Your task is to lift that geometry out of a solid block so the cavity is an exact-dimension negative of the model, then split the form horizontally along a gently curved parting line that lets me demold cleanly. Key functional details • Alignment: add dowel pins and matching holes for perfect half-to-half registration. • Pouring: integrate a single, straight channel feeding the cavity when both halves are clamped. • Finish: internal faces must be modeled for a polished finish; no additional texture. • Tolerance: keep the cavity true to the original file—no intentional clearances. Deliverables 1. Editable CAD source (SolidWorks or similar) plus neutral STEP files for both halves. 2. Dimensioned drawing or annotation showing pin positions, channel size, and parting line profile. 3. Quick screenshot set or PDF explaining assembly and pour orientation. Once I confirm fit and draft, we’ll close the job, so please allow a short round of tweaks.
