Inventor Drawing Tip - displaying Drill Tap size and 3D Part annotations

Your Autodesk Inventor drawing views that you place on your drawing sheet, and parts that have tapped holes created from the hole feature tool by default will always reference the minor diameter.

In some cases, you may want to dimension the view with the tap drill size.

When you measure the part's tapped hole the value that it returns is the minor diameter, so using the hole thread feature note does give you the correct information about the tap size and the pitch. However, for now I just want to display or include the tap drill size.

There are two options you can use for part annotations and drawing annotations.

Option 1

With the hole thread feature part annotation tool, you can add the tap drill size to the hole thread feature note by taking these steps:

Step 1: Double click to edit the hole thread feature note on the hole thread feature mini tool bar select edit hole note.

Step 2: In the hole note dialog box check the option tap drill and select OK.

Step 3: The hole thread feature note will now display with the tap drill size. The same steps above will do the same for the drawing view. The normal dimension on the left still displays the minor diameter.

 Option 2

To have the general dimension display as the tap drill size and not the minor diameter:

Step 1: With the part file open on the ribbon select the tools tab, and on the options panel select document settings.

Step 2: In the document settings dialog box change the tapped hole diameter to tap drill and select OK.

Step 3: The general dimension value now displays as the tap drill size and not the minor diameter, and changing the above setting will do the same for the view placed on the drawing sheet.
