The prompt
Create a 3D CAD model of an air-cooled IC engine cylinder with rectangular slotted cooling fins. The model consists of a square fin stack measuring approximately 160 mm × 170 mm. A central cylindrical boss is integrated on the top surface with a concentric circular bore for the engine cylinder. Four rectangular cooling fins, each 2 mm thick, are equally spaced vertically to form the fin stack. Eight elongated mounting slots are equally spaced on a bolt circle around the central boss. The slots are 8 mm wide with rounded ends. Include a raised circular flange around the center and maintain symmetry about both X and Y axes. The part should be fully parametric with editable dimensions and suitable for thermal analysis (ANSYS) and manufacturing. Generate the model in SolidWorks-compatible STEP format.
