Create a conceptual parametric CAD model

Create a conceptual parametric CAD model of a high-efficiency Vedic Yajna Kund. Overall dimensions: - Height: 450 mm - Top opening: 400 × 400 mm - Bottom footprint: 250 × 250 mm - Tapered square frustum geometry Construction: - Inner refractory firebrick combustion chamber, 50 mm wall thickness - 20 mm air gap surrounding the combustion chamber - 15 mm outer decorative shell (copper/brass) - Total double-wall construction Internal features: - Cast iron fuel grate positioned 100 mm above the base - Primary air plenum beneath the grate - Removable stainless-steel ash drawer below the plenum - Four adjustable sliding air intake vents centered on each side near the base - Internal preheated air channels running vertically through the wall cavity - Eight Ø10 mm secondary air injection ports located 50 mm below the top opening - Copper ghee drip inlet centered above the combustion chamber with adjustable valve - Optional removable spark arrestor ring at the top Model requirements: - Separate each major component into individual bodies: 1. Outer shell 2. Inner refractory chamber 3. Air channel cavity 4. Fuel grate 5. Ash drawer 6. Air vents 7. Ghee inlet 8. Spark arrestor Use realistic wall thicknesses, clean fillets where appropriate, and maintain symmetry about both center planes. The model should be fully parametric with editable dimensions. Generate as a conceptual engineering model only. It is not intended for fabrication and requires thermal, structural, and safety validation before construction.

Parameters

This model was generated without adjustable parameters. Open it in the editor to add your own dimensions.

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
