Windchill API call that gets only the direct drawing Referenced By?

[bbailey]

Hi All,

We are in the process of having some CAD verification software developed
and are running into an issue. Part of the requirements are that the tool
be able to traverse an objects (typically .prt or .asm) configuration and
check to see if any of the dependents are directly represented in a
drawing. The solution as delivered uses a call that returns ALL drawings
that the a dependent object appears in the structure above it. That is all
the way up the assembly structure, whether the object is a direct dependent
or not. This may be many in the case of a small piece part used in a large
assembly.

Is there a Windchill API call that only returns the Drawings that directly
reference an object?

Thanks,

Ben,

Here is an excerpt of the code that I use:


// Get references for drawing
QueryResult references = wt.epm.structure.EPMStructureHelper.service.
navigateReferences(latestDoc, null, false);

// Loop through all references if not null
while (references != null && references.hasMoreElements()) // may
want to add code to exit when found
{
// Get the next reference
EPMReferenceLink link = (EPMReferenceLink)
references.nextElement();

// Print Debug information for references found
System.out.print("Link Type: " + link.getDepType() + " ; ");
System.out.println("Reference Name: " + ((EPMDocumentMaster)
link.getReferences()).getName());

// Check to see if the link dependency type is for the master
model
if (link.getDepType() == 4) // '4' is the value for the master
reference in the drawing
{

// Get the EPM Document Master for the master model
reference in the drawing
EPMDocumentMaster epmDM = (EPMDocumentMaster)
link.getReferences();

// Do something with this information
// Add boolean to trigger exit from while loop?

} // end if drawing reference found

} // end while references and not updates

Thank you Mark! It works perfectly.

Hi Mark,

Can you please let me know if you do have any sample code to retrieve the latest drawing for a CAD Part or some sample API Regarding the same.

Thanks in advance.

Best Regards,

Aditya

Here is an exampleAPI to get Models (.prt /.asm) from drawing. You can trytweaking this code and check the reverse can be done.

List<epmdocument> models = new ArrayList<epmdocument>();
spec.appendClassList(EPMReferenceLink.class, false);

while (refIterations.hasMoreElements()) {
EPMDocument doc = (EPMDocument) perData[1];
models.add(doc);
}

}

ConfigSpec cSpec = null;
EPMAsStoredConfig asStoredcSpec = (EPMAsStoredConfig) asStoredConfigReference.getObject();

cSpec = EPMAsStoredConfigSpec.newEPMAsStoredConfigSpec(asStoredcSpec);
return null;
return null;
return cSpec;
Thanks
