1. Select Your Target Units: Toggle between Imperial system metrics (Feet, Inches) and Metric layout standards (Meters, Centimeters).

2. Configure Structural Type: Use the shape profile option list to toggle between Square/Slab metrics or Column/Cylinder dimensions.

3. Provide Dimensions: Input accurate physical spatial parameters. The 3D isometric model will automatically scale proportionally to verify your dimensional ratio.

4. Export Your Report: Review live output readings instantly, including breakdown yields for standard pre-mix bags. Click the download button to generate a fully branded PDF specification sheet containing your live 3D structure.

Square Slab Structure Logic:

Volume = Length × Width × Depth

Cylindrical Column Structure Logic:

Volume = π × (Diameter / 2)² × Depth

Calculated Industry Constants:

• Waste Margin: A 5% buffer is automatically applied to Gross Volume.
• Density: Estimated at 150 lbs per cubic foot (industry standard normal weight concrete).
• Bag Yields: 40lb bag = 0.30 ft³ | 60lb bag = 0.45 ft³ | 80lb bag = 0.60 ft³.
