Download Behavior for Attribute Mapping<br />

On download, the reverse is done; that is, the IBA name is mapped to the<br />

Pro/ENGINEER designated parameter name. It is possible that two or more<br />

Pro/ENGINEER designated parameters map to a single IBA. In this case, the<br />

Pro/ENGINEER designated parameter that is last among those that map to a<br />

common IBA is chosen.<br />

Note: Once added to the iba.properties file on the server side, IBA-to-designated<br />

parameter mappings should not be removed or modified. Doing so might affect<br />

the models already stored in the <strong>Windchill</strong> database (including historical data and<br />

released designs), particularly if such models have IBA values modified through<br />

the <strong>Windchill</strong> user interface (as opposed to modifications done in a<br />

Pro/ENGINEER session).<br />

For the same reason, new mappings should be added only for Pro/ENGINEER<br />

designated parameters that do not exist yet in the models already stored in the<br />

<strong>Windchill</strong> database. Therefore, it is strongly recommended that:<br />

• The <strong>Windchill</strong> server administrator adds any new mappings as part of the<br />

process of adding new IBA definitions in <strong>Windchill</strong>.<br />

• Workgroup Manager for Pro/ENGINEER and Pro/ENGINEER Wildfire<br />

PDM users do not designate Pro/ENGINEER parameters which are not<br />

mapped (implicitly or explicitly) onto a <strong>Windchill</strong> IBA; the upload service<br />

provides warnings in the Event Console in such cases, and users are<br />

encouraged to undesignate the parameters in Pro/ENGINEER and upload the<br />

models again.<br />

Customizing the Parameters in the Download Service<br />

<strong>Windchill</strong> provides a server-side delegate that can be used to insert parameters<br />

into a Pro/ENGINEER model upon download. This mechanism can be used to<br />

pass information from the server down to Pro/ENGINEER, where it can be used<br />

like any other Pro/ENGINEER parameter (for example, to place information on<br />

drawing forms). Parameters beginning with “PTC” or “PROI” are regarded as<br />

reserved system parameters and cannot be propagated by the customization. If<br />

they are added in the customization, they are ignored by the download service.<br />

Note: The customized parameters are provided to the client upon download and,<br />

unlike system parameters such as PTC_WM_ITERATION, are not updated in the<br />

Pro/ENGINEER session or the local cache after a <strong>Windchill</strong> operation (for<br />

example, check in).<br />

For example, if a customized parameter is assigned the value of the CAD<br />

document number, its value is provided to the client upon model download. If the<br />

CAD document is later renumbered, the value in the Pro/ENGINEER session or<br />

the client cache will not be automatically updated.<br />
