It is a separate window,strange
Is there any chance that that Part was inserted into another Part in the Assembly? I've had cases where the inserted Part would open anytime the Part it was inserted into, or an Assembly it was used in, was opened.
I see this fairly often.
I work a lot with split parts/assemblies.....I'll draw several bodies in one part file (typically weldment profiles).. then use the "save bodies" command to create individual part files for the bodies & a related assembly. Then, when I open one of the new split parts or an assembly containing a split part, sometimes the original part file is also opened...
I don't know if there is a way to control this behavior, or why it seems somewhat inconsistent. At any rate, its not too annoying.. just be sure you don't start editing the wrong file!
Set "Load Referenced Documents" to None and it would all be good
Deepak, I get this as well and have mine set to "changed". I'll give this a try but I think there's something else going on because I'll get a connector from a PCB assy that is opened and that doesn't make much sense.
See you in LA
Is it a "Read Only" file??
