Hi!

I'm new to Solidworks and I'm trying to figure out what the square brackets in the FeatureManager Design Tree mean.

I have found the float and fix-settings of parts within an assembly, but i just can't find information about the brackets. Sometimes i get fixed or floating parts with brackets around their names, sometimes fully defined parts gets brackets around the names, and sometimes i just don't get brackets at all. Does the brackets have something to do with the mates (or lack of mates) or am i searching the wrong area?

In the attached photo all parts have brackets around their names exept the fourth part (sidoväggar).

Thanks for help!!

Hilda
