LogicalAttributes.xml
位於 <Windchill>/codebase/LogicalAttributes.xml 的 LogicalAttributes.xml 檔案用於配置模型屬性對應 (從「邏輯形式」到其「外部形式」)。因此，呈現出物件間關聯性的所有模型屬性都需要對應。例如，部份針對 WTPart 至 WTPartMaster 參照而定義的項目如下：
<Class name="wt.part.WTPart">
<Property>
<LogicalForm>defaultUnit</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
wt.part.WTPartMaster~MBA|defaultUnit</ExternalForm>
</Property>
<Property>
<LogicalForm>masterReference</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
wt.part.WTPartMaster</ExternalForm>
</Property>
<Property>
<LogicalForm>name</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
wt.part.WTPartMaster~MBA|name</ExternalForm>
</Property>
<Property>
<LogicalForm>number</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
wt.part.WTPartMaster~MBA|number</ExternalForm>
</Property>
<Property>
<LogicalForm>organizationReference</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
wt.part.WTPartMaster~MBA|organizationReference^WCTYPE|

</Property>
<Property>
<LogicalForm>organizationName</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|

</Property>
<Property>
<LogicalForm>usedLineNumber</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
wt.part.WTPartMaster~MBA|uses@WCTYPE|
wt.part.WTPartUsageLink~MBA|
lineNumber.value</ExternalForm>
</Property>
<Property>
<LogicalForm>usedLink</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
wt.part.WTPartMaster~MBA|uses@WCTYPE|
wt.part.WTPartUsageLink</ExternalForm>
</Property>
</Class>
使用 "ext.cust.CustPart" 延伸 wt.part.WTPart 及 "ext.cust.SubPartMaster" 延伸 wt.part.WTPartMaster 的範例時，應將下列項目新增至名為 <Windchill>/codebase/LogicalAttributesSite.xml 的網站特定檔案：
<Class name="ext.cust.CustPart">
<Property>
<LogicalForm>defaultUnit</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
ext.cust.SubPartMaster~MBA|defaultUnit</ExternalForm>
</Property>
<Property>
<LogicalForm>masterReference</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
ext.cust.SubPartMaster</ExternalForm>
</Property>
<Property>
<LogicalForm>name</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
ext.cust.SubPartMaster~MBA|name</ExternalForm>
</Property>
<Property>
<LogicalForm>number</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
ext.cust.SubPartMaster~MBA|number</ExternalForm>
</Property>
<Property>
<LogicalForm>organizationReference</LogicalForm>
<ExternalForm>MBA|masterReference^WCTYPE|
