About the Curve through Points User Interface

The Curve through Points user interface consists of commands, tabs, and shortcut menus. Click Model > Datum > Curve > Curve through Points to open the Curve through Points tab.

Commands

• —Connects the point to the previous point with a spline connection.

• —Connects the point to the previous point with a straight connection.

◦ —Adds a fillet to the curve.

▪ R=—Sets the fillet radius value.

Tabs

• Placement

◦ Point set list—Displays a list of point sets defined for the curve. A point set is a point and its settings. When a point is selected in the list, the collector and settings for that point are displayed.

▪ Add Point—Adds a new point set to the point list.

▪ —Reorders the selected point upward in the points list.

▪ —Reorders the selected point downward in the points list.

◦ Point collector—Displays a point, vertex, curve end, or feature (for example, a datum point feature that includes several points) as a reference to place the curve.

◦ Spline—Uses a spline to connect the point to the previous point.

◦ Straight line—Uses a straight line to connect the point to the previous point.

▪ Add fillet check box—Adds a fillet to the curve.

▪ Radius box—Sets the fillet radius value.

▪ Group with equal radius points check box—Makes the point part of a logical group of points that have the same fillet radius.

◦ Place curve on surface check box—Forces the entire curve to be placed on the selected surface.

▪ Lie on surface—Uses a selected surface on which to place the curve.

▪ Surface collector—Displays a surface or quilt on which to place the curve.

• Ends Condition

◦ Curve side list—Selects the start point or end point of the curve and displays the point’s settings.

◦ End Condition list—Sets the condition type at the selected curve’s end.

▪ Free—Makes the curve free of any tangency constraint at this end.

▪ Tangent—Makes the curve tangent to a selected reference at this end.

▪ Tangent to collector—Displays the selected axis, edge, curve, plane, or surface to which the curve is tangent.

▪ Flip button—Flips the tangent direction to the other side of the reference. Available only if an edge is selected.

▪ Make end curve to be perpendicular check box—Makes the curve end perpendicular to a selected edge when the selected tangency reference is a surface or plane.

▪ Perpendicular to collector—Displays the edge to which the curve end is perpendicular.

▪ Flip button—Flips the perpendicular direction to the other side of the reference.

▪ Curvature continuous—Makes the curve tangent to a selected reference at this end, and applies a continuous curvature condition to the curve.

▪ Curvature continuous to collector—Displays the selected axis, edge, curve, plane, or surface to which the curve is tangent.

▪ Flip button—Flips the tangent direction to the other side of the reference. Available only if an edge is selected.

▪ Make end curve to be perpendicular check box—Makes the curve end perpendicular to a selected edge when the selected tangency reference is a surface or plane.

▪ Perpendicular to collector—Displays the edge to which the curve end is perpendicular.

▪ Flip button—Flips the perpendicular direction to the other side of the reference.

▪ Normal—Makes the curve normal to a selected reference at this end.

▪ Normal to collector—Displays the axis, edge, curve, plane, or surface to which the curve is normal.

▪ Flip button—Flips the normal direction to the other side of the reference.

• Options

◦ Tweak curve check box—Applies tweak settings to the curve.

▪ Tweak Curve Settings button—Opens the Modify Curve dialog box.

• Properties

◦ Name box—Sets a name for a feature.

◦ —Displays detailed component information in a browser.
