前幾日接到一個ModelCHECK集成配置的問題，按說ModelCHECK的集成配置雖有些繁瑣，但都是比較固定的東西，不會出什麼問題，但當時卻遇到一個煩人的報錯，，每次檢入模型時總是提示模型修改後未執行ModelCHECK，無論如何配置，包括完全重新設置客戶端，都沒有效果，MethodServer的日誌信息如下：

從日誌中可以看到，ModelCHECK的各項檢查條件都沒有問題，但系統卻仍然拋出“xxxxx.prt Model Check is not verified!“的錯誤，但MC_VERIFIED明明就是”真“啊！
需要注意的是，在英文版Windchill中，"MC_VERIFIED 真"會顯示爲"MC_VERIFIED yes"，在中文瀏覽器中查看時，MC_VERIFIED的值爲”是“，可以發現對於同一屬性值，Windchill本身卻給出了不同的中文翻譯，因此我懷疑這個問題就是由於軟件本地化做得不到位所造成的，即明明”MC_VERIFIED=真“的含義就是”MC_VERIFIED=yes“，但系統就是不能理解這一點。當然，至於背後的細節，就不得而知了。
事實上，基於多種原因，我都強烈建議大家在安裝Windchill時，安裝語言不要選擇中文，否則後續會有很多麻煩，而且安裝語言是沒辦法修改的，至於瀏覽器等界面上的語言，只要安裝了相應的語言包都可以正常使用，與安裝語言無關。如果安裝語言選擇了中文，那麼MethodServer日誌就是中文版的，不幸的是，這個中文版非常不成熟，中英文混雜在一起，中文翻譯有時像天書一樣讓人難以理解報錯信息到底在說什麼。而這次則又發現了一個更糟糕的弊端，即由於對布爾型屬性的本地化存在問題，直接導致了使用上的問題。最後我只得讓客戶棄用MC_VERIFIED，好在這實際上並沒有什麼影響，事實上Creo的官方幫助文檔中甚至建議不要使用MC_VERIFIED，因爲模型再生時會將MC_VERIFIED值變爲no，從而導致無法檢入，必須再次執行一次ModelCHECK，這有時會帶來非常煩人的問題。很多客戶反映Creo連接Windchill後麻煩增多，其實各種情況下的“再生”往往就是麻煩的根源。
