Generally, when we create indented BOM in SOLIDWORKS it will show all the part inside a assembly and subassembly in detail, of course indented BOM is built for that purpose.

Sometime when we use a standard assembly component item in SOLIDWORKS for creating model which is a bought out and SOLIDWORKS consider that as a assembly and it will list all the part in that assembly in indented BOM. Since it is a bought out item our requirement will be it need to appear as  a single part in our BOM

If we save that assembly as part and use it in the assembly all the kinematic motion will be loss and we can’t use the motion in the assembly

Let me insert a assembly to the assembly and then take the BOM for example.

In this case the hydraulic cylinder line item number 6 is a brought our item, and we need it as single line item, lets seen how we can do it in this blog
