Creating Dimensions and Associated Datums

You can create dimensions and associated datums on body in white surfaces.

Five hole types are available for tolerancing:

  • Cylindrical hole

  • Elongated hole

  • Rectangular hole with angular corners

  • Rectangular hole with rounded corners

  • Other hole from previous

Before you begin: Open an existing 3D representation.
