Tip
You should also name any new dimensions that you may want to change. These dimensions will have more meaning when you are placing the feature if they have names. Be aware that the two angled lines are parallel and equal length. This will enable you to get a fully defined sketch.

Reconfiguring the hole
Tip
Remember that to get the diameter dimensions shown in Figure 13.15 (instead of radius dimensions), you must use the dimension tool to select the centerline (construction line) and the line or endpoint on one side, and then move the cursor to the other side of the centerline to place the dimension (the order of selection does not matter). When the cursor crosses the centerline, the dimension will display as a diameter instead of a radius.
8. When you are done editing the sketch and renaming dimensions, exit the sketch.
9. Click the CBORE feature twice, or click it once and press F2 to rename it as SpecialHole.
10. Pre-select the same flat face that the first hole feature was placed on and then start the Hole Wizard again.
11. Place a #8-32 tapped hole, accept the default depth, and specify a center-to-center distance of .75 inches between it and the SpecialHole in the Horizontal or Vertical direction. Rename the radial dimension as MountRad.
12. Using a cylindrical face of the SpecialHole, make a circular pattern of the new tapped hole, creating a total of four instances of the tapped hole. Make the SpecialHole Feature red and the tapped hole and pattern yellow.
13. Split the FeatureManager window into two by using the splitter bar at the top. Change the lower panel to the ConfigurationManager.
14. Rename the Default configuration Size1.
15. Create a new configuration called Size2. Double-click the SpecialHole feature and change the dimension named C'Bore Dia to 1.5 inches. Be sure to change to This Configuration Only using the drop-down menu.
16. Make a dimension change for the MountRad dimension to 1 inch. The results to this point are shown in Figure 13.24.

17. Auto-create a design table by choosing Insert⇒Design Table and then selecting the Auto-Create option. Edit the design table to look like Figure 13.25. Hide or delete extra columns that don't match the data shown.

The design table for the SpecialHole feature
Tip
Remember that to fill the first two columns up to Size5, you can make the two-by-two selection of the Size1 and Size2 entries in the first two columns and pull down the handle in the lower-right corner of the selection box until the appropriate boxes are filled.
18. Manually fill in the C'Bore Dia values, but in cell D3, type the equation =C3/2+.25. Then use the same Fill technique to populate cells D3 to D7. Click outside of the Design Table to close it.
19. Test the configurations to make sure that they all work.
20. In the Design Library, browse to a folder where you would like to put this library feature. (Make sure that it is not used by assemblies or sheet metal forming tools.) Click a face created by the SpecialHole feature and drag the feature into the lower pane of the Design Library. The Add to Library PropertyManager should appear on the left.
21. Although you selected a feature and dragged it into the library, the Items to Add field appears blank. Select the SpecialHole, tapped hole, and circular pattern features using Ctrl+select for multiple selections, either through the detachable PropertyManager, the split FeatureManager, or the flyout FeatureManager. Selecting the features from the graphics window does not work.
22. Position and zoom the view of the part so that when it is saved, you see a good preview of the library feature. Also, if you have not changed your background color from blue to white, this
