I have a drawing of a routing assembly and in the BOM some pipe files have this bracket around the parts icon and I can't figure out what it is.
This symbol means that the part is saved internally in the assembly. It doesn't have an external file associated to it. Route lines will be created in this fashion so it makes sense that all the routes in your assembly will display like this.
You will notice if you right click on the part in the assembly and save in an external file these will disappear from the BoM.
That was it, thanks.
