Custom templates extend the tool’s power beyond defaults, enabling professional-grade workflows.

Under the Hood

The Hole Wizard uses a database of standard hole definitions linked to industry norms. When you select a hole type and size, it generates a parametric feature with the correct geometry and metadata. It also creates references for threads and countersinks as separate but linked features. The tool updates these features dynamically if you change parameters or reposition holes.

Why designed this way?

The Hole Wizard was designed to automate repetitive hole creation while ensuring compliance with standards. Manual hole creation was error-prone and slow. Using a database-driven approach allows easy updates when standards change and supports customization. This design balances flexibility with reliability.
