问题：
当我尝试在 RFEM 和 Rhino 之间导出/导入模型时，出现关于 RF-COM 的错误消息。 "Export Error: Error to write data, message: The demo version of RF‑COM allows models with a maximum of 12 members, 2 surfaces, and 2 solids only". How do I fix this?
答案：
Download the following link:
http://www.dlubal.de/download/temp/Rhino_Com_patch.zip
Then:
(1) Please close RFEM and Rhino.
(2) Open the ZIP folder and double click the *.rhi file.
(3) Select the "Anyone who uses this computer" option in the Rhino Package Installer.
