The Hole Sequence Dialog

Hole Group - This group contains a drop down of all the hole groups for the selected feature. If the feature contains multiple groups, move all of the Holes from the Remaining Hole List, into the Sorted Hole List, then select the next group from the Hole Group list and repeat the process.

Sorted Hole List - This group can be thought of as the machine sequence list and shows all holes that have been assigned a position in that sequence. All holes in this list will be have their highlight set to red in the graphics area. Highlighting holes in this list will change their color in the graphics area from red, to pink. There will always be one highlighted hole in this list.

- moves the selected hole up one position in the Sorted Hole List.

- moves the selected hole down one position in the Sorted Hole List.

- deletes the selected hole from the Sorted Hole List.

Remaining Hole List - This group contains all holes that have not been assigned a position in the machine sequence. All holes in this list will be highlighted blue in the graphics area. Highlighted holes in this list will have their highlight color changed from blue, to green.

- resets the lists to default.

Steps

1) Getting Familiar

1. Left-click in the graphics area, away from your holes.
   
   In moving the mouse slightly, you will notice that the mouse location is being traced.
   
   While the mouse location is being traced, Hole Selection Mode is active. The mouse location continues to be traced until you left-click again.
   
   

2. Left-click the mouse in the graphics area again.
   
   In moving the mouse, you will notice the mouse location is no longer being traced.
   
   Hole Selection Mode is deactivated.
   
   

3. Left-click to activate Hole Selection Mode and move the mouse slightly to verify the mouse location is being traced.
   
   

4. Click and hold the scroll wheel on the mouse, or use a 3D mouse to rotate the model slightly.
   
   If you do not rotate the model too much, you will notice Hole Selection Mode remains active.
   
   If the model is rotated over a particular angle threshold, Hole Selection Mode terminates and the mouse location is no longer traced.
   
   This is to help keep you from selecting holes accidentally while rotating a model.
   
   

5. Practice entering and exiting Hole Selection Mode and get a feel for the amount of rotation allowed without exiting Hole Selection Mode.
   
   

2) Sorting Holes

1. While in Hole Selection Mode, move your mouse over the first hole to be machined.
   

Tip: When the model is rotated, notice hole geometry is highlighted with an arc at the top, an arc at the bottom, and a line connecting them. To select the hole, it is not necessary to touch the highlighted color exactly, as a fully cylindrical bounding area is created within those highlights

The highlight color of the hole changes to pink and it is added to the Sorted Hole List.

2. Continue dragging the mouse through the holes in the order to be machined, until all are selected.
   
   
   
   Notice there is the path traced out by the mouse in blue, and another purple path with dotted lines and arrows. This path shows the sequence in which the holes will be machined.
   
   

3) Clearing Sequence

1. Click the icon under the Remaining Hole List to reset the sequence.
   
   All holes are removed from the Sorted Hole List and moved back to the Remaining Hole List.
   
   

4) Skipping Holes

1. Enter into Hole Selection Mode to select the holes again.
   
   

2. Take a moment to skip a hole during the selection process.
   
   
   
   

3. Exit Hole Selection Mode and notice the sequence path skips the hole we purposely missed.
   
   
   
   

4) Inserting Holes

1. Before entering into Hole Selection Mode, move your mouse into the bounding area of the hole to machined immediately prior to the skipped hole.
   
   
   
   

2. Click inside of the bounding area of the Sorted Hole to be machined prior to the hole we intend to insert.
   
   
   
   The Sorted Hole highlights pink.
   
   The Remaining Holes we select next, are insert into the Sorted Hole List directly after the hole whose bounding box we were in while activating Hole Selection Mode.
   
   

3. Drag the mouse through the bounding area of the Remaining Holes.
   
    
   
   All holes are now sorted.
   
   Take a moment to notice the sequence path laid out in purple.
   
   

4) Adjusting Sorted Hole List

1. When a Sorted Hole is selected in the list, the arrow icons can be used to adjust its position in the list.
   
   Take a moment to highlight a Sorted Hole and adjust its position in the list and observe the resulting changed in the sequence path.
