MotionLinks Object

Derived from: Base Object
Defined in namespace "adsk::fusion" and the header file is <Fusion/Components/MotionLinks.h>

Description

The collection of MotionLinks in this component. This provides access to all existing MotionLinks and supports the ability to create new MotionLinks.

Name	Description
add	Creates a new MotionLink.
classType	Static function that all classes support that returns the type of the class as a string. The returned string matches the string returned by the objectType property. For example if you have a reference to an object and you want to check if it's a SketchLine you can use myObject.objectType == fusion.SketchLine.classType().
createInput	Creates a MotionLinkInput object, which is the API equivalent to the Motion Link command dialog. You can use methods and properties on the returned object to set the desired options, similar to providing input and setting options in the MotionLink command dialog. Once the settings are defined you call the MotionLinks.add method passing in the MotionLinkInput object to create the actual MotionLink.
item	Function that returns the specified MotionLink using an index into the collection.
itemByName	Function that returns the specified MotionLink using a name.

Name	Description
count	Returns number of MotionLinks in the collection.
isValid	Indicates if this object is still valid, i.e. hasn't been deleted or some other action done to invalidate the reference.
objectType	This property is supported by all objects in the API and returns a string that contains the full name (namespace::objecttype) describing the type of the object. It's often useful to use this in combination with the classType method to see if an object is a certain type. For example: if obj.objectType == adsk.core.Point3D.classType():
