Understanding parts lists is essential for organizing and managing the components required for a project. In the context of engineering, construction, and manufacturing, a parts list (also known as a Bill of Materials or BOM) is a comprehensive list of raw materials, components, and assemblies needed to construct, manufacture, or repair a product or project.
### Components of a Parts List
1. **Item Number**:
- Unique identifier for each part.
- Helps in tracking and referencing parts easily.
2. **Part Name/Description**:
- Detailed description of the part.
- Includes specifications such as dimensions, material, and any other relevant characteristics.
3. **Quantity**:
- Number of each part required.
- Essential for ordering and inventory management.
4. **Part Number/Code**:
- Manufacturer's or supplier's unique code for the part.
- Useful for ordering and ensuring the correct part is used.
5. **Supplier Information**:
- Details of the supplier or manufacturer.
- Includes contact information and possibly pricing.
6. **Unit of Measure**:
- How the part is measured (e.g., pieces, meters, kilograms).
- Important for ordering the correct amount.
7. **Cost**:
- Unit cost of each part.
- Used for budgeting and cost management.
8. **Notes/Comments**:
- Any additional information relevant to the part.
- Could include assembly instructions, special handling requirements, or substitution options.
### Creating a Parts List in AutoCAD
AutoCAD offers features to create and manage parts lists, particularly useful in CAD drawings for engineering projects.
#### Step-by-Step Guide to Creating a Parts List in AutoCAD
1. **Draft the Drawing**:
- Complete the drawing with all the necessary components and parts.
- Use commands like `LINE`, `CIRCLE`, `POLYLINE` to draw the components.
2. **Insert Blocks for Components**:
- Use the `BLOCK` command to create reusable components.
- Each block should represent a different part.
3. **Annotate the Drawing**:
- Use the `TEXT` or `MTEXT` commands to label parts.
- Include details such as part names, numbers, and descriptions.
4. **Create an Attribute Block**:
- Use the `ATTDEF` command to define attributes for blocks.
- Attributes can include part number, description, quantity, and any other relevant information.
Example:
```
ATTDEF
Enter the Tag: PART_NO
Enter the Prompt: Enter Part Number:
Enter the Default: 1234
Specify insertion point: (click or type coordinates)
```
5. **Insert Attribute Blocks**:
- Insert the blocks with attributes into the drawing.
- Use the `INSERT` command and fill in the attribute values as prompted.
6. **Extract Attributes to Create the Parts List**:
- Use the `DATAEXTRACTION` command to extract block attributes to a table.
- Follow the Data Extraction wizard to select the blocks and attributes you want to include in your parts list.
Example:
```

00:00Now that we have our surface displaying the way we want, let's look at adding some labels to this.
00:06The first one we'll look at is adding a contour label.
00:09If we go to the Annotate tab at the top, and then click the tag at the very top here to bring up our Add Labels dialog.
00:16The first thing we'll want to do is to choose the feature.
00:19So in this case, we're wanting to label a surface.
00:23The label type is going to be a single contour.
00:28So you'll notice we have the options to add multiple or multiples at intervals.
00:33So by choosing Contour Single, we then have the options for major and minor contours and also users.
00:40So if this matches what we want, which it does, we're working with an existing surface.
00:44So we're going to use these styles and click Add.
00:47All I need to do now is select a single contour line.
00:51And one thing that will confuse it here is if our snaps are turned on.
00:55So you'll notice along the boundary there, I'm getting a snap.
00:58So what I'm going to do is turn off my snaps.
01:00So the shortcut for that is the F3 key on the keyboard.
01:04And now I'll click along this contour line.
01:07When I zoom in, you'll see that we have our first label.
01:11Now the first thing I'm going to want to do is make sure that's a whole number.
01:14The first thing I want to change is making this contour label a whole number.
01:19So this is at elevation 257.
01:22So I know that's a minor contour.
01:25So I will edit the minor contour label style, clicking the blue button with the pencil.
01:31On the Layout tab, I'm concerned about the contents of this label.
01:36So if I right-click on the value here, it reveals the ellipses, which will allow me to edit that.
01:41So I'll click the button.
01:43And we get our text component editor.
01:45Now, this can seem a little bit daunting at first because it looks like computer code,
01:49and you don't have to know anything special.
01:51All you need to do is click any part of that text.
01:54And over here on the properties, we know that we're looking at feet,
01:57and we're working currently at a precision of 100.
02:00So we'll change that by clicking on it twice and choosing 1.
02:04And now we want to commit these changes.
02:06Right now, all I've done is make some changes over in this side of the window.
02:10It hasn't updated my label yet.
02:12So don't forget the magic arrow to commit your changes to the label.
02:16And then I'll click OK twice.
02:20And now my label displays as I would like.
02:23The next part is going to be a spot label.
02:28So I'll change my label type over to a spot elevation.
02:32We get to choose our label style here.
02:35So I'm going to be displaying the elevation.
02:38We can make these look however we want, display with whatever text in it, whatever size.
02:42But for now, we're going to choose this default label style.
02:45And then we also can determine whether or not we want a marker to be placed along that.
02:50So based on your drafting standards, you would want to have something here that represents what you want to see.
02:55I'm going to turn off the marker style in this case and just get the spot elevation.
03:01I'm going to click Add.
03:04I'm going to click here.
03:08And we get our first label.
03:10Now I'm going to click Escape to end that command.
03:12And here, based on the label style, we're working at 100 still.
03:17If I click that label, you can see I have two nodes.
03:21The diamond is going to allow me to move it.
03:23And if I move it, it's going to start reading the elevation at that point on the surface.
03:27If I choose the top one, that's going to put the label into a drag state.
03:31And I'll get a leader.
03:34If at any time we want to reset this, all we have to do is select it, right-click, Reset Label.
03:41The other option we have here is doing spot labels on a grid.
03:45I'm going to go up to the north side of the site here.
03:48And we're going to choose Spot Elevations on Grid.
03:53Again, we're going to choose our style and whether or not we want a marker.
03:57I'm going to take the defaults here and click Add.
03:59I'm paying attention to the command line down here.
04:02There's going to be several questions that ask us that we need to pay attention to.
04:05So, Specify Grid Base Point.
04:07This is going to be the lower left of the grid.
04:10So I'll click down here.
04:12And whether or not we want to rotate that grid, I'm just going to accept it to be zero.
04:17And on what spacing do we want to create these points?
04:21Let's do it on a 10-foot X and 10 feet.
04:26Now, I'm going to choose the limits of this by choosing the upper right corner.
04:31And then it's asking me, are you sure this looks the way you want it to look?
04:35And if it's good, we click on Yes.
04:39Now, if this grid looks good to us, we can say no, we don't want to make any changes.
04:44And it will create our gridded points.
04:49Again, each one of these you can modify as needed if you need to put one in a drag state or reset it.
04:58And there's the overview of labels for surfaces.
