The prompt
Create a 3D CAD model of a heavy-duty industrial steel formwork mold assembly for casting a precast concrete pipe culvert. The assembly must consist of two main components: a straight cylindrical inner mold core and a two-piece split-cylinder outer mold jacket, both exactly 1000mm in vertical height. Structural Specifications: 1. Finished Pipe Cavity: The inner core mold must have an outer radius of 450mm (900mm diameter). The outer mold jacket must have an inner radius of 560mm (1120mm diameter), creating a uniform 110mm concrete wall gap thickness between them from top to bottom. 2. Outer Mold Jacket: Formed by two identical semi-cylindrical 4mm thick steel plates. Each half features heavy vertical connection flanges on both open seams made from 50mm x 5mm flat bar, with aligned clearance holes for M14 structural assembly bolts spaced evenly along the 1000mm height. 3. Outer Reinforcement Grid: Each outer shell half is reinforced on its exterior surface with a welded grid. It must include straight vertical stiffeners made from 50mm x 5mm flat bar spaced longitudinally, and horizontal curved hoop ribs made from 50mm x 5mm flat bar segments to provide hoop-stress resistance. 4. Inner Mold Core: Formed by a 3mm thick steel plate skin, reinforced internally with an equivalent structural grid layout using 50mm x 5mm vertical flat bars and 50mm x 5mm horizontal curved reinforcement ribs. The final model should show the complete vertical assembly sitting square, looking like a straight-walled, heavy-duty industrial steel silo mold with external reinforcing rings and bolted side seams.
