Creating a GDT Angularity Call-out in CAM2

Preparation

• Create the datum features as detailed in the following articles:
  • Applying Datums to Features in CAM2
  • Creating Composite Datums in CAM2
• Measure the features that require the GDT call-out

Creating the GDT Call-out

• Select the GDT tab
• Highlight the required feature in the Feature panel
• From the ribbon select  Angularity

The GDT panel will open in the lower LH corner of the UI

Note: If the GDT icon is ‘greyed-out’ this details that the selected feature does not support this call-out.

• Within the GDT panel:
  1. Click into the tolerance, and enter the required value
  2. Select the required datum
     
• If aligned to CAD, the result will be shown in the GDT label displayed in the 3D viewer.
• If not aligned to CAD, it is also necessary to manually enter the ‘nominal’ angle between the two features:
  • Right click to right of the tolerance cell (indicated below by #)
  • Then select Override Length and Angle
    
  • Check the Override Angle box
  • Enter the Nominal angle
  • Select OK
    

The call-out will be calculated and the result will be shown in the GDT label displayed in the 3D viewer.

Note: To display results in the GDT label select via View > GDT Label > Level of Detail

Copying GDT Call-outs to Other features

This allows multiple features of the same type to have the same call-out applied

• Apply the call-out to the first feature
• Highlight the first feature
• Right click and select Copy Tolerances
• Multi-select other features
• Right click and select Paste Tolerances
• Message ‘Do you also want to paste the GDT tolerances?’, select Yes

The GDT call-out will be applied to the selected features, and the GDT label will be displayed.
