ScratchPolygonSelections Object Preview

Derived from: Base Object
Defined in namespace "adsk::cam" and the header file is <Cam/GeometrySelections/ScratchPolygonSelections.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

Collection for all scratch polygon selections to be passed to a CadScratchPolygonsParameterValue or CadScratchPolygonsForMoveStartPointsParameterValue object. This is a read-only container. It returns the scratch polygon selections associated with the parent parameter value object, but does not write to it. To apply changes done to the collection and the selections it contains, the corresponding ParameterValue's applyScratchPolygonSelections() needs to be called.

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().

clear

Clears all entries.

createNewScratchPolygonSelection

Creates a new scratch polygon selection and adds it to the end of the collection.

item

Function that returns the specified scratch polygon selection object using an index into the collection.

remove

Function that removes the specified scratch polygon selection object using an index in the collection.

removeByObject

Function that removes the specified scratch polygon selection object from the collection.

Properties

Name Description
count The number of items 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():
