Database attributes concepts

There are certain concepts that must be understood when dealing with database attributes.

General Behavior

The value of each database attribute is read automatically from Teamcenter only once in your NX session. The Teamcenter value is checked and, if necessary, the attribute is updated in the NX part file the first time the value is required (for example, to update the display of annotation). After that, the Teamcenter value is not checked again until you either close the part and then reopen it, or use the Reload function to force an update.

The reason that database attributes behave in this way is to avoid time overheads when you read an attribute and when you load a part. If you are not accessing the database attributes, then no processing is done to update them, as it is not necessary.

각 데이터베이스 속성의 값은 NX 세션에서 한 번만 Teamcenter에서 자동으로 읽습니다. Teamcenter 값이 확인되고 필요한 경우 값이 처음 필요할 때 NX 부품 파일에서 속성이 업데이트됩니다(예: 주석 표시 업데이트). 그 후 Teamcenter 값은 부품을 닫았다가 다시 열거나 다시 로드 기능을 사용하여 강제로 업데이트할 때까지 다시 확인되지 않습니다.

데이터베이스 속성이 이러한 방식으로 동작하는 이유는 속성을 읽을 때와 부품을 로드할 때 시간 오버헤드를 피하기 위한 것입니다. 데이터베이스 속성에 액세스하지 않는 경우 필요하지 않으므로 업데이트를 위한 처리가 수행되지 않습니다.

 

Save a part File

When you save a part file, all the database attributes in the part file are checked against the Teamcenter database, and updated if necessary. If, for any reason, the database attribute values are invalid (i.e., the value is mapped to a permitted List Of Values, but does not match any in the list), then the save will be aborted. In interactive mode (Save or Clone Import), a warning message is output and the user is offered the chance to edit the incorrect value and to retry. In non-interactive mode (ug_import), the job is abandoned. This attempt to update the values guarantees that all database attributes in a part file are up to date at the time of the save. This is done so that normally it is not necessary to edit attributes in part files when exporting them out of the database.

부품 파일을 저장할 때 부품 파일의 모든 데이터베이스 속성이 Teamcenter 데이터베이스에 대해 확인되고 필요한 경우 업데이트됩니다. 어떤 이유로든 데이터베이스 속성 값이 유효하지 않은 경우(즉, 값이 허용된 값 목록에 매핑되지만 목록의 어느 것과도 일치하지 않는 경우) 저장이 중단됩니다. 대화식 모드(저장 또는 복제 가져오기)에서 경고 메시지가 출력되고 사용자에게 잘못된 값을 편집하고 다시 시도할 기회가 제공됩니다. 비대화식 모드(ug_import)에서는 작업이 중단됩니다. 값을 업데이트하려고 하면 부품 파일의 모든 데이터베이스 속성이 저장 시 최신 상태로 유지됩니다. 이는 일반적으로 데이터베이스 외부로 내보낼 때 부품 파일의 속성을 편집할 필요가 없도록 하기 위해 수행됩니다.

 

Create a New Part File

When you create a new part file in the NX session, some attributes will have no value initially, but will acquire a value when saved. This is because they are mapped to properties in Teamcenter in objects which are only created when saved, and which have default initial values.
