Quick question. I don't know if there is something wrong with a settings option in this part file, or if Solidworks has some issue. Normally when I use the equation manager on a part with more than one configuration, I'm able to set config-specific global variables and equations. However, I have one part that doesn't allow me to do this. Any ideas? The image below shows what I see with this problem-part in the top panel, and the normal expected behavior below.
[New Addition] I've attached the problem file if you want to check it out on your machine. There will be an in-context reference to a block in the parent assembly layout sketch (which I'd prefer not to share), but I don't think that will prevent the file from loading. I'm currently managing all the configuration info via a design table, since I couldn't do it using the equation manager.
