Hole Tool

This tool creates a hole through a 3D object e.g. a padded sketch. The icon can be found on the “Sketch-Based Features” toolbar, and looks like this;

Create a similar part to the one below;

Hole 1


Once you’ve done this, click the hole tool icon and then select the top plane of your pad as the reference. The following dialogue box should appear:

Hole 2

In the Extension tab, the depth and diameter of the hole can be specified. An offset can be introduced for extra clearance if required.

By using the positioning sketch tool, the hole position can be specified. The white asterisk represents the centre of the hole, which can be moved and constrained as you would normally in sketch mode. Under the “Type” tab  a variety of holes can be selected, such as “simple”, “counterbored” and “countersunk”.

Finally, under the Thread Definition tab, a threaded hole can be created. In the thread definition section, under “Type”, standard threads can be selected. After the details have been entered, press ok and a hole will be created. The helical thread detail will not appear on the part, which is common to almost all CAD packages. It is good practice to chamfer the hole to remove the top thread. Without the chamfer, it is possible that the first part of the thread can be pulled and damaged when the male thread is tightened. The chamfer should be ØT x 90° where T is the thread diameter
