Rotation Dynamic Properties for 2D

The 2D Rotation dynamic is similar to the 2D Size and Location dynamics, but with an angular movement that pivots. You can add a Rotation dynamic to a 2D shape by click the Rotation dynamic icon on the Dynamics tab or the 2D Dynamics ribbon When you apply rotation to an object you need to hook that object up to a data source and specify the angle through which the rotation occurs.

The rotation dynamic supports:

A single movement
A response to a fluctuating data source
An input control based on rotation, which is controlled by the Dial property or an animation

The table below lists the Rotation dynamic properties for 2D GraphWorX64. (For the 3D version, refer to Rotation Dynamic Properties for 3D.) The properties listed in the table are those you would set as part of a Rotation dynamic's definition. You determine the default values for the Rotation dynamic's properties by setting them on the Preferences tab; for more information about these preferences, refer to New Rotation Default Settings.

Unique Properties of Rotation Dynamics

Property	Settings	Description
Data Section
DataSource	An input, value, expression, or OPC data source	Data connections can be typed directly into the DataSource. Click the ellipsis [...] button and in Data Browser you can select tags in the system. You can also create Expressions in the Data Browser.
DragDropDataSource	True or False	True indicates that the data source can, during runtime, be dragged by a user and dropped into another component so that the rotation dynamic affects the component it is dropped into.
LowLimit	Value	Low limit is used as a boundary condition in animation.
HighLimit	Value	High limit is used as a boundary condition in animation.
ActiveWhen	Range setting	Set the discrete ranges in which animation will occur.
Dynamic Behavior
AnimationMode	Analog or Discrete	Analog – The rotation of the object is determined by values coming from the data source. Discrete – The start and stop of the object's rotation is determined by values coming from the data source.
Dial	True or False	Responds to user input of rotation to change a data source value. (Analog AnimationMode only)
StartPercent	Value
EndPercent	Value
Clockwise	True or False	Sets the direction of the rotation. Use 360 to 0 for clockwise and 0 to 360 (start to end) for counterclockwise.
StartAngle	A value between 0 and 360	The start angle in degrees
EndAngle	A value between 0 and 360	The end angle in degrees
PivotOffsetX	Number of pixels	Moves the rotational axis a number of pixels in the X direction
PivotOffsetY	Number of pixels	Moves the rotational axis a number of pixels in the Y direction
Dynamic Behavior - Detents (Analog AnimationMode only)
DetentType	None, Number of Detents, Delta Value	Detents are the steps that an animation can have.
DetentValue	Number	The number is the number of steps used in the animation. Use more steps for smoother animation.
DetentOrigin	Value	Specifies the starting analog value from which subsequent steps are calculated.
Dynamic Behavior - Discrete (Discrete AnimationMode only)
StartDelay	Number	The number of milliseconds that will pass before animation begins in runtime; you can use a data source for this number.
Duration	Number	The number of milliseconds over which the animation will transpire; you can use a data source for this number.
SkipInitialDuration	True or False
AccelerationRatio	0 to 100
DecelerationRatio	0 to 100
AnimateWhenTrue	True or False
ReverseAnimateWhenFalse	True or False
AutoReverse	True or False
RepeatCount	Number
FillBehavior	Holdend or Stop
FreezeWhenNotAnimating	True or False
Dynamic Behavior - Toggle (Discrete AnimationMode only)
PeriodicToggleRate	Number	The number of milliseconds that will pass between flash state changes; you can use a data source for this number.
DynamicStateWhenToggleOff	True or False

ShowToolTip	True or False

Edit Dynamic On Screen	(Click to enable)	Clicking this hyperlink lets you work directly on the work surface; change the rotation and final position of the object by dragging the object to spin it around.

Example

To illustrate the use of rotation dynamics to create a windmill effect:

Create a circle, then four propeller shaped ovals and group them to look like a windmill.
With the windmill selected click the Rotation dynamic and set the DataSource to localsim:ramp.
The Clockwise property should be True, AnimationMode is Analog, and you should set the StartAngle to 360 and the EndAngle to 0.
Click the Runtime button and observe that the windmill rotates clockwise.
