Applying Datums to Features in CAM2

CAM2-Beauty.png

Overview

Datum features are required to create datum alignments and perform GDT calculations.

Download a PDF of this procedure:  GDT002: Applying Datums to Features

Preparation

  1. Measure or create the datum features
    • If using CAD, the recommended workflow is:
      • Pick from CAD – create datum features on CAD
      • Select Nominals in Features panel, right click Add Measurement
      • Measure the corresponding datum features
    • If CAD is not used, the user must manually enter the nominal information for:
      • Feature position (x,y,z) – some features require multiple entries
      • Feature vector (i,j,k)
      • Feature Size

Note: This can be done via the Feature Information panel, or by using the Key-In options.

Applying Datums to Features

 

  • Once created, select the first datum feature in the Features Panel.
  • Right click, select Assign Datum, then choose Datum letter and type

Tip: for circle datums, normally a linear datum is used.

  • Datum labels will be displayed in the Feature panel and 3D viewer

  • Datums feature can now be used for datum alignments and GDT callouts

Note: A datum feature must have both actual and nominal information to allow it to be used in a datum alignment.
