Tech Tip: How to Use Hole Callouts in Onshape Drawings

Accurate drawing annotations are critical for clear manufacturing intent, especially when detailing complex fasteners, counterbores, or threaded holes. Manual entry leads to errors, so Onshape automates the entire process.

Watch the video below to see how Onshape automatically generates precise hole callouts, handles imported geometry, and gives you total control over callout formatting.

Instant Feature Metadata Extraction

When you select a hole feature in Onshape Drawings using the Hole Callout tool, Onshape automatically reads the Part Studio feature data. Thread specifications, counterbore/countersink dimensions, and depth symbols pop up instantly with zero manual entry.

Tagging Imported & Non-Native Models

Working with STEP files or imported geometry? Use custom features like Tag Hole in your Part Studio to assign standard hole intelligence to non-native geometry. This ensures your downstream drawings generate accurate, standardized callouts every time.

Full Customization Control

Need to add notes or tweak display order? Double-click any callout on your sheet to reorder information, adjust tap drill depths, or add custom prefix/suffix notes – all while maintaining direct parametric links to your model.
