https://www.ptcusercommunity.com/t5/Windchill/Compare-to-Part-Structure-not-available-grayed-out/m-p/693485#M62993 <P>I've got a Creo CAD assembly in Windchill that is linked to a WTPart using the Owner link. The part structure will successfully build. The problem is that for some reason on the CAD page, the "compare to part structure" button is grayed out. On the WTPart page, I am able to get the comparison.</P> <P>I've checked for failed placements, and that doesn't seem to be the issue as the structure will successfully build. I've tried unassociating the WTPart and reassociating it. I've tried checking out the CAD model regenerating, saving, and checking back in. I've even tried suppressing everything and then checking back in. The compare button continues to be grayed out.&nbsp;</P> <P>Any ideas how to resolve?&nbsp;</P> Fri, 16 Oct 2020 19:36:14 GMT joe_morton 2020-10-16T19:36:14Z https://www.ptcusercommunity.com/t5/Windchill/Compare-to-Part-Structure-not-available-grayed-out/m-p/693485#M62993 <P>I've got a Creo CAD assembly in Windchill that is linked to a WTPart using the Owner link.

Clearing the NO_PART value restores the functionality.</P> Mon, 16 Mar 2026 21:26:55 GMT https://www.ptcusercommunity.com/t5/Windchill/Compare-to-Part-Structure-not-available-grayed-out/m-p/1058824#M88516 joe_morton 2026-03-16T21:26:55Z
