## Existing Relations

Relations | Displays relations inferenced automatically during sketching or created manually with Add Relations. When you select a relation in the list, a callout is highlighted in the graphics area. | |

Information | Displays the status of the selected sketch entity (Fully Defined, Under Defined, and so on). |

## Add Relations

You can add relations to the selected entity. The list includes only relations that are possible for the selected entity.

## Options

For construction | Converts the entity to construction geometry. |

Auto tangency | Applies tangent relations at each endpoint of the curve and selects the top vertex of the curve. |

## Parameters

You can specify any appropriate combination of the following parameters to define the parabola if the parabola is not constrained by relations. When you change one or more parameters, the other parameters update automatically.

Start X Coordinate | ||

Start Y Coordinate | ||

End X Coordinate | ||

End Y Coordinate | ||

Shoulder X Coordinate | Sets the X value for the height of the curve. The height is measured from the endpoints to the top of the curve. | |

Shoulder Y Coordinate | Sets the Y value for the height of the curve. The height is measured from the endpoints to the top of the curve. | |

Top vertex's X Coordinate | Sets the X value for the intersection of the tangent lines at the curve’s endpoints. | |

Top vertex's Y Coordinate | Sets the Y value for the intersection of the tangent lines at the curve’s endpoints. | |

Rho | Sets the ratio of the height of the curve to the height of the top vertex. | |

Radius of curvature at the shoulder | Sets the radius of curvature at the shoulder point along the curve. |
