AdditiveSubNestFuture Object Preview

Derived from: CAMFutureBase Object
Defined in namespace "adsk::cam" and the header file is <Cam/CAM/AdditiveSubNestFuture.h>

PreviewThis functionality is provided as a preview of intended future API capabilities. You are encouraged to use it and report any problems or suggestions using the Fusion API and Scripts forum.

Because this is a preview of future functionality, there is the possibility that it will change, which will possibly break any existing programs that use this functionality. Because of that, you should never deliver any programs that use any preview capabilities. For a distributed program, you should wait until it has moved from preview to released state.

Description

Used to check the state and get back the results of a Sub-Nest generation triggered via AdditiveSetupUtility.generateSubNest(). The future reports completion as soon as the underlying arrangement task has finished.

Methods

Name Description
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().

Properties

Name Description
error Gets the last encountered error message generated on the task thread.
isGenerationCompleted Returns true once the underlying task has finished.
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():
progress Returns the progress as a percentage value between 0.0% and 100.0%.
warning Gets the last encountered warning message generated on the task thread.
