From a configured roof to a bill of materials.
A roof manufacturer needs more than a 3D view: dimensions and covering choices must produce inspectable quantities. This technical example uses the existing roof model and bill-of-materials functions. It is a software demonstration, not a customer case study or a roofing quotation.
Reproduce the example
In the full configurator, choose the two-slope roof and generic metal covering. Set length to 10 m, depth to 7 m, wall height to 3 m, pitch to 30° and eaves overhang to 0.4 m. These are explicit test inputs, not a recommended building design.
Define the product
The roof preset, dimensions and covering form the input configuration. For your catalogue, this starts with supported shapes, component data and the choices your customers may make.
Apply the rules
The model calculates the sloped roof area, while the BOM applies component lengths and effective coverage. This preset uses 0.47 m² per panel and a 5% waste allowance, not a universal supplier rule.
Inspect the quantities
The table shows actual outputs from the repository functions. Changing a dimension changes the geometry and quantities. The 70 m² building footprint is not the sloped roof area.
Export the material list
The full configurator exports CSV rows with description, unit, quantity and reference price fields. Those fields describe the software output; demo rates are not a supplier offer.
Plan the business-system connection
CSV is a starting point for a handoff. Mapping components to your catalogue, validating prices and connecting ERP or CRM require a separate technical review. This example does not demonstrate a live ERP integration.
Outputs for this exact two-slope preset| Output | Value |
|---|
| Building footprint | 70 m² |
|---|
| Sloped roof area | 97.27 m² |
|---|
| Ridge length | 10.8 m |
|---|
| Eaves length | 21.6 m |
|---|
| Covering panels | 218 pieces |
|---|
| Ridge pieces | 30 pieces |
|---|
| Gutter pieces | 8 pieces |

Panel coverage, waste allowance, effective ridge length (0.37 m) and gutter length (3 m) are assumptions of this demo preset. Other products and drawn-roof modes may use different calculations. Validate the catalogue, construction and purchasing quantities before production.
