To Create a Standard Coaxial Hole
1. Select an axis on the model. This is your primary placement reference for the Coaxial hole. The selection is highlighted.
2. Click Model > Hole. The Hole tab opens.
The Coaxial placement type is selected on the Placement tab.
The hole preview geometry is aligned to the selected axis.
3. Click to create a Standard hole. The Standard hole options are shown.
4. Click the Offset References collector on the Placement tab to activate it and select a surface or a datum plane as the offset reference to constrain the hole.
5. Select the desired hole chart in the box adjacent to (Thread Type) on the Hole tab. Thread Type enables you to select industry-standard hole charts (ISO, UNC, or UNF).
6. Type or select a screw size in the box adjacent to .
 
* 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.
7. To define the hole depth, select a depth option from the Depth Options list, or drag the depth handle in the graphics window.
8. To add countersink to your hole, click .
9. To define the countersink diameter or angle, click the Shape tab and type or select a new countersink diameter or countersink angle in the corresponding boxes.
10. To add counterbore to your hole, click .
11. To define the counterbore diameter or depth, click the Shape tab and type or select a new counterbore diameter or counterbore depth in the corresponding boxes.
12. To ensure that the entire top of the hole intersects the outside of the solid geometry, on the Shape tab, make sure that the Top Clearance check box is selected.
13. Click .
