The Part Offset command increases or reduces geometry size within a part using diameter values, commonly used to compensate for cutting variations or adjust hole and feature sizes.
🔹 How to Use
- Start command: Launch Part Offset and select the geometry to offset.
Select geometries: Pick one or multiple geometries within the part that need size adjustment.
- Enter offset value: Input the diameter offset value (positive adds material, negative removes material).
- Apply changes: Execute the command to modify the selected geometry sizes.
🔹 Offset Logic
- Positive values: Add material (holes get smaller, externals get bigger).
- Negative values: Remove material (holes get bigger, externals get smaller).
- Diameter-based: Values represent diameter changes (updated from radius in versions before 2024.1).
🧠Tips
- Compensation workflow: If a hole measures 0.13mm too small, use -0.13mm offset to remove material and increase hole size.
- Waterjet compensation: Small circular holes often cut slightly undersized in waterjet cutting - this command provides easy correction.
- Single part modification: Current version only modifies the specific part you select, not copies of the same part.
- Diameter values: Remember that offset values are diameter-based, not radius (changed in version 2024.1).
- Material logic: Positive values add material thickness, negative values remove material thickness.
