Create/Modify Point Motion Actuator

(Template Builder) Build → Actuators → Point Motion → New/Modify            Shared Dialog Box
Creates or modifies a point-motion actuator. Learn more about point-motion actuators.
 
For the option:
Do the following:
Actuator Name
If creating a point motion actuator, enter a name for it.
If modifying a point motion actuator, enter its database name.
I Part/J Part
Enter the name of the body that the motion will act upon.
I Coordinate Reference
Enter a Coordinate Reference to locate the point on the I part at which the motion will act.
J Construction Frame
Enter a Construction Frames to locate the point on the J part at which the motion will act. The Z axis of this marker will also define the motion direction.
If one or both of the parts are flexible bodies, the following option is shown:
Selected Node, Closest Node, Closest Interface Node
Select the method to define the attachment reaction node(s).
■If you select Selected Node, you must specify the node(s) manually, and the attachment will be hardcoded to these node IDs.
■If you select Closest Node, an expression will be used to parameterize the attachment to the closest node on the flexible body.
■If you select Closest Interface Node, an expression will be used to parameterize the attachment to the closest interface node on the flexible body.
Type of Freedom
Select translational or rotational motion.
Application (optional)
Enter a string for the application area.
Identifier (optional)
Select translational or rotational motion.
Function
Enter the function of time that defines the motion.
Select to use the Function or Expression Builder to define a function. For information on the Function or Expression Builder, see Function Builder.
Excitation Mode
Select displacement, velocity or acceleration.
Displacement Limits (optional)
Enter a numerical string that defines the displacement limits of the actuator(s).
Velocity Limits (optional)
Enter a numerical string that defines the velocity limits of the actuator(s).
Acceleration Limits (optional)
Enter a numerical string that defines the acceleration limits of the actuator(s).
Units (optional)
Enter a literal string to identify the units used in the actuator definition. This string is currently not used.
Active
Select one of the following:
■on: Actuator is active.
■off: Actuator is not active.
You can also use the Actuator Set Activity dialog box to define the activity of any actuator.
Select to display a dialog box where you can add multi-line comments to any entity, to describe its purpose and function. Your template-based product displays different comments dialog boxes, depending on the entity type for which you want to record comments:
■If recording comments for modeling entities in Standard Interface, your template-based product displays the Entity Comments dialog box.
■If recording comments for any other entity type, your template-based product displays the Modify Comment dialog box.
Learn about Recording Comments.
 
Note:  
The limits are not used in the current version of your template-based product. They are optional and create string variables under the actuator user-defined element (UDE) instance; the same applies to the unit, application, and identifier strings.
