The hole callout feature allows us to easily present information related to a particular hole in our model. This information includes the diameters of the hole, the length of the hole, and any standards related to the creation of the hole. To demonstrate this feature, we will use it on the hole shown in the right-hand view of our drawing. Note that the following image also highlights the difference between the normal Smart Dimension we used earlier and the Hole Callout feature:

To add a hole callout, follow these steps:

1. Under the Annotation tab, select Hole Callout, as highlighted in the following screenshot:

2. Click on the circular hole we want to call out. In this case, it is the circle indicated in the right-hand view, as shown in the following image. Once we click on the hole, the hole callout will appear, along with all the information linked to that particular hole:

3. Delete the smart dimension input to make the drawing look cleaner. 

This concludes how we can use a hole callout. At this point, our drawing has all the required views, display types, and dimensions and annotations. Next, we will learn how to adjust the information block, which contains information that's relevant to us, such as its name, number, company, designer, and so on.
