FoldBendLineDefinition Object Preview

Derived from: Base Object
Defined in namespace "adsk::fusion" and the header file is <Fusion/SheetMetal/FoldBendLineDefinition.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

Base class that provides access to the information defining a single bend line within a fold feature. Used when querying or editing an existing fold via FoldFeature.bendLines.

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().

deleteMe

Deletes this definition from the collection fold bend lines.

Properties

Name Description
bendAngle Returns the ModelParameter that defines the bend angle. Edit the value using the returned parameter. If the isTemporary property is true, this property will return null and the bendAngleValue property should be used to get and set the bend angle.
bendAngleValue Gets and sets the bend angle of the fold line.

If the isTemporary property is false, this property will return null, and the bendAngle property should be used to access the parameter that controls the bend angle.
bendLine Returns the sketch curve (bend line) that defines this bend.
isBendReliefAllowed Gets and sets whether bend relief is applied at the ends of this bend line. To set this property, position the timeline marker immediately before the fold feature.
isTemporary Specifies if this FoldBendLineDefinition is associated with a FoldFeatureInput or a FoldFeature. Returns true when associated with an input object, which means the persistent fold feature has not yet been created.
isValid Indicates if this object is still valid, i.e. hasn't been deleted or some other action done to invalidate the reference.
linePosition Gets and sets the position of the bend line relative to the bend (start, center, or end) in the flat state. To set this property, position the timeline marker immediately before the fold feature.
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():
