What am I doing wrong with Weldments? I made a weldment of sq. steel tube from sketches. I needed to add plates, so I created new part files of the different shapes, inserted them using Insert> Part..., move them into place everything is fine until I sdave, close and reopen the files. Then I get a "->?" next to each part I've inserted, when I right-click on each inserted part to List External References, it says "part out of context".
Any ideas? Thanks Whit
