To Preselect Datum References

As a time saving measure, you can first select any of the following combinations of references in the graphics window, and then click Model > Plane to define a fully constrained datum plane. This feature allows you to quickly define datum planes without using the Datum Plane dialog box.

References | Results |

Two coplanar edges or two axes (must be coplanar but not collinear) | Datum plane is created constrained through the references |

Three datum points or vertices (must not be collinear) | Datum plane is created constrained through each of the datum points/vertices. |

A datum plane or planar surface and two datum points or vertices (points or vertices must not be collinear with the normal to the plane) | Datum plane is created normal to plane through the selected points. |

A datum point and an axis or straight edge/curve (point must not be collinear with the axis or edge) | Datum plane is created constrained through the datum point and the axis/edge. |
