The prompt
Create a parametric 3D CAD assembly file for an astronomical telescope pier setup, consisting of four distinct parts aligned along a single vertical center axis: 1. UNDERGROUND FOUNDATION (Sub-grade Footing): A solid concrete foundation block buried entirely underground. The top surface of this footing measures 500mm wide by 500mm deep, and it extends vertically downward for 600mm. The bottom 300mm of the footing flares out into an 'elephant's foot' pyramid shape, reaching a maximum base dimension of 650mm wide by 650mm deep. Total overall vertical depth of the foundation is 900mm. 2. LOWER COLUMN PART (Concrete Block 1): A rectangular hollow masonry block standing vertically on its end, resting flush on top of the underground foundation at ground level (0mm). Outer cross-section dimensions are 190mm wide by 190mm deep. Vertical height is 390mm. It features a hollow internal cavity running all the way through it. 3. UPPER COLUMN PART (Concrete Block 2): A second identical hollow masonry block (190mm x 190mm cross-section, 390mm vertical height) stacked perfectly flush on top of the first block. The total combined height of the two stacked blocks above ground level is 780mm. 4. INTERNAL ANCHOR RODS: Two vertical M16 steel threaded rods running parallel inside the hollow core of the stacked blocks. The rods are anchored deep inside the underground concrete foundation and protrude out from the top of the upper concrete block at a height of 780mm. 5. TOP INTERFACE (Adapter Plate): A flat, solid rectangular metal plate measuring 400mm long by 200mm wide, with a thickness of 12mm. This plate sits perfectly centered and flush on top of the upper concrete block at a starting height of 780mm, with the internal M16 rods passing through it to clamp the assembly together. The plate includes a centered 12mm clear hole through the middle for the telescope mount attachment.
