What is the role of 3D modeling in evaluating cost estimates during the design phase?

3D modeling is critical for evaluating cost estimates during the design phase by enabling accurate visualization, precise quantification of design elements, and streamlined cost analysis. It allows precise measurement of materials, components, and spatial relationships. For example, in construction, 3D models can automatically calculate material volumes (e.g., concrete, steel), while in manufacturing, they clarify part dimensions and assembly steps to detail production costs. By integrating 3D modeling early, potential cost overruns or material inefficiencies are identified before design finalization, reducing reliance on manual calculations and minimizing estimation errors. Ultimately, this makes cost estimates more reliable and supports informed decision-making in the design phase.
