To Create a Tapered Hole
1. Click > 
Hole. The Hole tab opens.

Tapered to change the hole profile to tapered.
Tapered to change the hole profile to tapered.4. Select a surface on the model where you want to place the hole. The selection is highlighted. This is your placement reference.
 | You can also select the placement reference before you activate the hole tool. |
5. To change the hole placement type select a new type from the placement Type box on the Placement tab.
6. Drag the offset placement reference handles to the appropriate references to constrain the hole. As you drag each handle, the available references are highlighted as your pointer moves over them. The system automatically snaps the handle to the reference and adds them to the Offset References collector on the Placement tab.
7. To orient the hole to be parallel to or perpendicular to a reference:
a. Click the Placement tab, click the Hole orientation collector, and select a planar, axial, or linear reference.
b. Click 
to make the hole parallel to the orientation reference, or click 
to make the hole perpendicular to the orientation reference.

Thread type list, select the industry-standard hole chart (ISO_7/1, NPT, or NPTF).

Screw size box, type or select a screw size.
Screw size box, type or select a screw size.| | If you enter a screw size that is not listed, the system selects the closest screw size. You can also drag the hole diameter handle to select a screw size. |
10. To define the tapered hole depth, drag the depth handle in the graphics window, or type the value in the input panel.
| | To define a new depth by dragging the depth handle, or by typing or selecting a new value, you must select the  Blind Blind depth option. |
11. To add a straight drill, on the Shape tab, select a depth option from the Straight drill list, or from the shortcut menu. The following options are available:
◦ Blind—Drills from the placement reference to a specified depth.
Blind—Drills from the placement reference to a specified depth.◦ 
To Next—Drills to the next surface.

Through All—Drills through all surfaces.
Through All—Drills through all surfaces.◦ 
Through Until—Drills to intersect with the selected surface.

To Reference—Drills to the selected surface, quilt, body, plane, curve, or point.
To Reference—Drills to the selected surface, quilt, body, plane, curve, or point.◦ 
None—Does not add a straight drill.
None—Does not add a straight drill.12. To add a slanted surface at the bottom of the tapered drill, select the Tapered tip check box.
| | The straight drill diameter is calculated differently depending on whether the Tapered tip check box is selected. • When the Tapered tip check box is selected, then the straight drill diameter is the same as the straight drill diameter in the hole file. • When the Tapered tip check box is not selected, then the straight hole diameter is calculated from the minor diameter, taper depth, and taper angle using the following formula: STRAIGHT_DEC = MINOR_DIAM_START - 2×(DEF_HOLE_DEPTH × tan(TAPER_ANGLE/2)) After the initial calculation, the straight hole diameter becomes the driving dimension, and the taper depth becomes the driven dimension. |
13. To add countersink to the hole:
a. Click 
Countersink on the Hole tab.

Lightweight.
Lightweight.16. To ensure that the entire top of the hole intersects the outside of the solid geometry, on the Shape tab, select the Top Clearance check box.
17. To select the bodies from which geometry is removed, click the Body Options tab and select an option:
◦ To cut geometry from all the bodies that the feature passes through, select All.
◦ To cut geometry from selected bodies:
1. Select Selected.
2. Click the body collector, and then select bodies from which to cut geometry.
