A method for generating an interactive 2D projection of a 3D model includes steps of applying hierarchical defect data to the 3D model of a multi-part object, generating heatmap data based at least in part on the hierarchical defect data, and overlaying the heatmap data on the 3D model. The method also includes steps of extracting data corresponding to the 3D model and including the heatmap data after the overlaying step, and creating the interactive 2D projection based on the extracted data.
