rhino-to-rfem-structural-model

Activate ONLY when BOTH the source is Rhino AND the requested destination is an RFEM structural member model, or when reviewing/resuming that exact forward conversion. If either condition is absent, do not open this SKILL.md. Do not load for Rhino-only meshing/modelling, RFEM-only modelling/results, reverse RFEM-to-Rhino export, or plugin installation. 仅用于 Rhino 到 RFEM 完整杆系的正向转换及该转换的审查、恢复；不匹配时不要读取本技能。
