The holes selected will be displayed on the left hand side of the dialog box.  You can use the Move Up and Move Down buttons to move a selected Hole Feature up/down in the list.

Move Up

This button moves the selected item up (i.e., higher) in the list.  Items are machined in the order listed.

Move Down

This button moves the selected item down (i.e., lower) in the list.  Items are machined in the order listed.

Remove All

Pick this button to Remove All Regions from the list.  The geometry itself is not deleted from the part model.

Remove Active

Pick this button to Remove the selected Active region from the list.  You can select multiple Regions from the list using the Ctrl key and then pick this button to remove them all.  The geometry itself is not deleted from the part model.

Select Drill Points/Circles

Pick the Select button to select features from the part and assign them to the Selected Machining Feature(s) list for the current operation.

Select Pre-Defined

If you pick this button, the Select Pre-defined Machining Regions dialog will display, allowing you to select one or more Regions.  This operation dialog will then re-appear with your region selections listed. Pre-Defined Regions can be created using the options on the Regions tab of the Machining Objects Browser.

Use this option to drill along a selected 2D or 3D curve and then complete the Hole Instances and Direction parameters listed below. Use one of the Select buttons listed below on this dialog.

Drill Holes Along Curve

Hole Instances

Use these options to define the total number of holes to locate along the selected curve. The first hole will be located at the start point of the curve. You can either define the Number of Holes or the Distance Between the holes. It is highly recommended that you perform a cut material simulation to verify that the holes are located how you want them to be.

Direction

The first hole is always located at the start point of the curve. Select Natural to place the first hole at the start point. Select Reversed to place the first hole at the end point of the curve.

Check the Use Diameter Filter box to select holes within a specified diameter range.  You can enter Minimum Diameter and Maximum Diameter values.  If you select the Pick button, the diameter value of the selected feature will be entered into the field. Note: These filter settings are saved with the part file.  If your control geometry changes, you are warned to check your filter settings before proceeding.
