help with derived parts

I have an assembly with a part in it that is derived from another part in
the same assembly, my question is how can i get this derived part to show up
in my bill off materials. My BOM shows up with 30 parts that are the same
but it should show 29 parts and 1 part wich is the derived part. Or is this
not possible

 

Being only a newbi on this system I'm not quite sure how to figure all of
this out. I thought the derived part would show up somewhere in my assembly
but i can't seem to find any reference to it anywhere. Why dosn't the
derived part show in my config file of the part that it has come from.

 

A derived part is a part that is created by inserting the body(s) of another
part file into a new part file (this has nothing to do with configurations).
Or by creating (a) mirrored body(s) think of it like an external ref in
Acad, that you can modify without changing the origional file yet if the
origional file changes the derived part will update to those changes.
Anyway when you create a derived part from the part module of SW you save it
to a location on your system somewhere. I believe the default location is
the same folder as the origional part. If you create it this way it will
not affect any assembly opened or not. If you create the derived part as a
mirrored component from within an assembly then the new component will be
within the assembly the same distance from the mirror plane but on the other
side.

Now if you created the derived part and it IS in your assembly, but as you
say it is not showing up on your BOM that means one of 2 things. It is
either suppressed, or it has the same fields in the Custom properties and
the same BOM part number identification which is found at the bottom of the
configuration properties. The custom properties can be found at
File>Properties>Custom Properties and File>Properties>Configuration Specific
on the BOM the fields under Configuration Specific over ride the fields
under Custom Properties. If you are using the default BOM then the Custom
Properties field you want to fill in differently for each part is
"Description".

Hope this helps

Thanks Corey i think i understand now, so simple when someone exsplains it
in laymans terms.
Buy the way don't want to be a burden but do you have any idea how to get
the size of a Flat pattern (lenght x width y )from a part. When i place a
Dim in the Flat pattern its fine then when i suppress Flat-Pattern the dim
changes to the folded part. I'm trying to extract the flat part size on
about 600 pieces without unfolding all of them

 

You just found the "changing length syndrome." SW does just what you asked
it to do and that's to show you a distance between the 2 ends of the part.
Unfortunately it also evaluates that distance when the edges fold up and get
closer, so it's not still a flat pattern dimension. One way to get around
that is to put a sketch line in that is the summation of the neutral axis
distances in the part. Then a dimension on that line is always correct.
However, it may not be worth the effort. Your choice.
