- [Instructor] Sometimes when you create a bill of materials
inside your drawing,
it doesn't include all of the information
or all the items that you actually want someone to use.
So for example, in this assembly that I have on the screen
maybe I want someone to put some grease
in various locations.
That's technically an item that they need
to create this part.
It's pretty easy to edit this.
It works just like any other tables
that you're used to using in a Microsoft format.
So I'm just going to click over here.
I'm going to right click on this left side
and you can see if I go to insert,
I can insert columns or I can insert rows.
So I'm going to insert a row below
and I'm at the last row already.
And now I can double click on here
and it's going to ask me anytime you edit a cell, are you sure?
Because these cells are linked
to custom properties in the background.
You can say, don't show again if you want,
but I usually leave this option on
and let me know when I'm editing something
that's linked or overriding a custom property.
So I'm going to say yes.
And I'm going to type in grease
and I'm going to go over here with my balloon,
I'm going to point to this joint right here.
I'm going to go back and edit my balloon
and just change this to text and put eight.
Now I have a balloon showing where I want the grease
and inside of my bill of materials
I have an item that's listed as grease.
And if I want to specify anything about the description
and I'm going to hit yes to override this again,
I can say for example,
I want to use lithium grease for this part and I hit enter.
At any point, if you want to wipe that out
you can go back in here, right click and say, delete row.
Also at any time, if you double click and edit
any of these features and you break it,
like right now this has a value inside of it
so it's asking me this question a little bit differently.
I'm going to say, keep the link.
Now, if you keep the link
then you won't be able to override it.
But if you break the link
it's not going to say short anymore
but you can always restore it by clearing it out.
So let me show you how this plays out.
So I'm going to break this link.
Let's say, I don't want to call it short,
I'm going to call it short three and hit enter.
I had to edit this part number for some reason,
it doesn't match the file name
and I don't have access to the file name to edit it.
I've just edited it by double clicking on it
and hit break link and hitting enter.
If I want to clear that out
so it goes back to the original file name.
I double click again, select everything, hit delete
and now hit return.
And it goes back to the original custom property
that was pulling from this drawing view
from item number six.
I mean, notice here, my balloon didn't go away
'cause I just dropped a custom balloon.
But when you're doing custom edits like that
it doesn't link to anything.
It doesn't link to an item that exists necessarily.
So the other thing you could do
in those kinds of situations
is create empty parts inside of your Solidworks assembly
and assign those custom properties to them
so that they show up correctly,
give them the right part name and the description
and use them the appropriate number of times.
Then you can use that to kind of fake your grease
into your build materials.
And that'll actually give you a link that you can control
and it will have a link to the assembly files
that we do edit it, take those quantities in or out
it'll reflect inside of the bill of materials.
Otherwise you do run the risk
of just relying on the fact that you have to remember
that you custom edited these items.
So it's really important to remember
when you do go in and edit a bill of materials
where you've done so,
so that if you have to make more edits in the future
it makes sense if your bill of materials
isn't updating properly, for example
