Define what accuracy means
A correct-looking roof, a measured frame dimension and a correct quote total answer different questions. Specify the product references, units and permissible geometry the implementation must reproduce. Distinguish approximate buyer inputs from surveyed dimensions and identify who verifies the actual site.
Reconcile representative configurations
Use manufacturer drawings and checked quote examples for a standard unit, a boundary size and an enclosed design. Compare overall dimensions with opening dimensions and verify which references each input uses. Check component identifiers and quantities before totals. If two inputs describe the same physical length in different units, confirm they produce equivalent geometry and quantities.
Test changes before release
Alter a dimension, accessory and price list and review the matching specification and documents. Required drawings and production handoffs need their own acceptance checks. Structural suitability and applicable site approvals remain responsibilities in the project process, not a consequence of a 3D model's appearance.
