Only the Part to Part Structure compare allows Filter Selection on opening. Compare (CAD) to Part Structure defaults to and ONLY allows Latest:Working filtering. It should allow filtering just as in Structure view.
Currently, in the CAD assembly Structure tab, you can set a filter (Latest:Released, As Stored, As Matured) on the CAD structure displayed. Then right there is the Compare to Part Structure button! But it doesn't compare what you have displayed to the associated WTPart structure. No !!! It compares the Latest:Working filtered version of the CAD assembly to it's associated WTPart structure. That is VERY BAD/ CONFUSING/ NONSENSICAL !!!
We have multiple design teams (New Product/ Maintenance/ Commonality) working on changing items in a structure on DIFFERENT Change Notices. We do NOT want to do the Compare (CAD) to Part Structure on the Latest:Working, but, AT MINIMUM, between the Structure tab displayed filtered CAD Structure to its' associated WTPart Structure. But, since the general Compare Tool utility is designed to allow the setting of filters, why not just TAKE OFF the arbitrary limitation of the Compare (CAD) to Part Structure to ONLY allow Latest:Working.
