Autonumbering and Creo

I know what you're talking about and I dealt with that before I ever enabled auto numbering.  These are being correctly issued one at a time, but unfortunately the way Creo interacts with Windchill it "burns up" numbers unnecessarily.  (See the original post.)

Normally I'm using just one number generator for cad documents. It's just a sad subject. Instead of making fundamental changes to the system, PTC simply patches a few minor problems.

I don't know how long that PTC sticks to this old Workspace and WGM functionality...

There are two possibilities to change the number generator for model, assembly and drawings:

1. OIR Configuration. This works only when creating new CAD-Files with the "New CAD-Document" wizard in the workspace and within Creo 5 direct (I belief). It won't work when you do a Save-As in Creo since the docType is empty.

<AttributeValues objType="wt.epm.EPMDocument">
 <AttrValue id="number" algorithm="com.ptc.windchill.enterprise.revisionControlled.server.impl.NumberGenerator">
 <Value algorithm="wt.rule.algorithm.CaseBranch">
 <Value algorithm="wt.rule.algorithm.EqualsTest">
 <Attr id="docType"/>
 <Arg>CADCOMPONENT</Arg>
 </Value>
 <Arg>{GEN:wt.enterprise.SequenceGenerator:CADCOMPONENT_seq:7:0}</Arg>
 <Value algorithm="wt.rule.algorithm.EqualsTest">
 <Attr id="docType"/>
 <Arg>CADASSEMBLY</Arg>
 </Value>
 <Arg>{GEN:wt.enterprise.SequenceGenerator:CADASSEMBLY_seq:7:0}</Arg>
 <Value algorithm="wt.rule.algorithm.EqualsTest">
 <Attr id="docType"/>
 <Arg>CADDRAWING</Arg>
 </Value>
 <Arg>{GEN:wt.enterprise.SequenceGenerator:CADDRAWING_seq:7:0}</Arg>
 <Arg>{GEN:wt.enterprise.SequenceGenerator:CADFALLBACK_seq:7:0}</Arg>
 </Value>
 </AttrValue>
</AttributeValues>

2. The more convenience way is to create subtypes for each docType. This is necessary, since a cad model has a mass and density etc. but not a drawing. This enables you also to have different attributes on the different types:

• Create subtypes (these have to be identical with the xml code below!)
• Create OIR for all the subtypes
• Create OIR for a fall back, e.g. for frames, material files, etc.
• Create a file called EPMDefaultSoftTypes.xml and paste (and edit) the code to it
  

  <?xml version="1.0" encoding="UTF-8"?>
  
  <SoftTypeDescriptor xmlns='http://www.ptc.com/SoftTypeDescriptor'
   xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
   xsi:schemaLocation='http://www.ptc.com SoftTypeDescriptor.xsd'>
  
  	<!-- Default soft types for the authoring application : PROE -->
  	<AuthAppSoftTypeInfo authAppName="PROE">
  		<!-- Zuweisung betrifft EPM-Dokumente -->
  		<ObjectClassInfo classType="EPMDocument">
  			<!-- Creo Drawing -->
  			<ObjectTypeInfo type="CADDRAWING">
  				<SoftTypeInfo softTypeId="${internet_domain_name}.CreoDrawing"/>
  				<SoftTypeInfo subType="*" softTypeId="${internet_domain_name}.CreoDrawing"/>
  			</ObjectTypeInfo>
  			<!-- Creo Assembly -->
  			<ObjectTypeInfo type="CADASSEMBLY">
  				<SoftTypeInfo softTypeId="${internet_domain_name}.CreoAssembly"/>
  				<SoftTypeInfo subType="*" softTypeId="${internet_domain_name}.CreoAssembly"/>
  			</ObjectTypeInfo>
  			<!-- Creo Part / Sheet Part -->
  			<ObjectTypeInfo type="CADCOMPONENT">
  				<SoftTypeInfo softTypeId="${internet_domain_name}.CreoPart"/>
  				<SoftTypeInfo subType="*" softTypeId="${internet_domain_name}.CreoPart"/>
  			</ObjectTypeInfo>
  			<!-- Other Creo-Files like frames, etc. -->
  			<ObjectTypeInfo type="*">
  				<SoftTypeInfo softTypeId="${internet_domain_name}.CreoDocument"/>
  				<SoftTypeInfo subType="*" softTypeId="${internet_domain_name}.CreoDocument"/>
  			</ObjectTypeInfo>
  		</ObjectClassInfo>
  	</AuthAppSoftTypeInfo>
  </SoftTypeDescriptor>

• There is also a utility to convert the existing cad-documents to the new types:
  wt.epm.util.SoftTypeChangeUtility

Hope this helps
