為什么導入的sat模型無法正常顯示

請教大家一個問題，我在CST中導入了一個sat文件模型，在MWS工作室算完后，保存，關閉文件。在重新打開這個CST文檔后卻發現我的sat模型不見了，無法正常顯示！重新計算了幾次都不行，安裝了兩個版本也都是這種情況。請問大家有遇到這種情況的嗎？

沒有，回答完畢。
參考CST MWS幫助文件《CAD Data Import and Export Overview》和《Import SAT File》。
Copy file to project
In general, the option 'Copy file to project' should be activated for the import.
When 'Copy file to project' is activated, the original import file will be copied to the Model/3D sub folder of the project. For the import, the copied file will be converted to a sat file, and will be saved to the Model/3D sub folder of the project, too. During a rebuild, the sat file is usually read except when the copied import file in the Model/3D sub folder is newer.
When 'Copy file to project' is not activated, only the converted sat file will be saved to the project. During a rebuild, the sat file is usually read except when a newer file of the import exists.
This option is available for the following imports: SAT, STL, IGES, VDAFS, STEP, Autodesk Inventor, PROE (Part), CATIA4, CATIA5 (Catpart), Nastran, Microstripes, Conventor, Mecadtron, HFSS, DXF, GDSII, Gerber.
Please note: For CATIA5 Catproduct files and ProE Assembly files this option is always deactivated, and these imports behave like explained above.

建議你檢查下單位設置
比如設置成了Hz,再設置個m單位,弄個open add space邊界,就可能縮的很小看不到
