Nest reports showed "-" for every part weight on N26-295 because the nest and its drawings store Stainless Steel 310 with density 0: materials are picked by name and grade, and nothing copies a density onto them. The densities live in the machine material defaults, and for this nest not even on its own machine (CL-980 lists only 304; 310 is on CI FIBER 4020). The desktop now resolves a catalog density before capturing the report: the nest machine's exact name and grade, any machine's exact name and grade, then the same material name. A density stored on the nest still wins, and the drawing's own material stays the last fallback. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
