I hate to say it, but SolidWorks has different icons in the browser for fully constraint parts and parts that has some degrees of freedom left...
I would like to have that also within Inventor.
It is a usefull feature and (ex-) SolidWorks engineers ak me all the time, how in Inventor, they can easily see, if a part is fully constraint.
The "Degrees of Freedom" feature doesn't work with large assemblies. It would be nice, if you can see it in the browser.
See a suggestion how it can look in the attachment.
