Auxiliary Curve

Auxiliary Curve

Insert a auxiliary curve between two points.

Properties

Specify the following parameters in the Properties panel.

Link
Link Number	Specifies the link number. You can change the automatically generated Link Number value.
Geometry Type
Creation Type	Specifies the type of curve to draw: Arc: General Arc: Three Points Parabola: General
Arc Tessellation	Specifies the number of line segments used to represent the curve. Note: This value must be between 2 and 100. Click to open the Expression Editor, where you can enter or calculate a value.
Geometry Properties
Start Point	Specifies the start point of the curve. Note: The point may be either a Point or an Auxiliary Point.
Center Point (Arc: General)	Specifies the center point (either Point or Auxiliary Point) of a general arc.
Arc Point (Arc: 3 Points)	Specifies the through point (either Point or Auxiliary Point) of a three-point arc.
End Point	Specifies the end point (either Point or Auxiliary Point) of the curve.
Mid-Ordinate (Parabola: General)	Specifies the distance between the lowest point of a parabola and its vertex. Click to open the Expression Editor, where you can enter or calculate a value.
Miscellaneous
Comment	Indicates notes about the curve. Comments can be displayed in the Preview panel.

Example

To see an example of how this geometry element is used, open the following Sample PKT file:

Auxiliary Curve Example.pkt

The example PKT contains one auxiliary curve, one auxiliary link, and one link. In the flowchart, the curve is defined by a start point, an end point, and a parameter of radius. To review its parameters, select the auxiliary curve in the flowchart, and then check the Geometry Properties section of the Properties panel.
