WtPart and CAD Document build failed in Windchill along with this we are seeing there is a difference in wtpart version and corresponding CAD version ?
CAD Part version is keep etting changed but its wtPart remained at initial one.
Please help
What is the message when build fails?
I presume you are updating part structure from CAD, not the other way around?
If you are updating WTPart structure from CAD, the WTPart has to iterate (not the CAD Doc) to complete the the build process. Build changes the part structure (ie changes the part uses table). Those change have to be stored in a new part version. The difference in version to CAD is not a problem, when the part iterates it carries forward the CAD association from the previous WTPart version.
Your screen shot shows the build status of the parts as "Excluded". Is this deliberate? This means exclude from build operation. If you need them to be driven by cad, set for build on each one and select "build" option. This will update the build state to "to be built". The presence in structure and quantity will then be driven by CAD following the next build operation.
If you looking to update CAD to reflect manually created WTPart structure you need the WTParts on left side of compare table. In this case CAD iterates and you need a work space for that to happen in.
