UnfoldFeatureInput Object Preview

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

This class defines the methods and properties that pertain to the definition of an unfold feature input.

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
bendFaces Gets and sets the bend faces to unfold. For each bend, specify either the inner cylindrical face, the outer cylindrical face, or both. Partner faces of the same bend (including side faces) are resolved automatically when the feature is added. Passing a cylindrical face that is not part of any bend on the sheet metal body (for example a hole or a fillet face) causes add to fail with an error. This property is ignored when isUnfoldAllBends is true.
isUnfoldAllBends Gets and sets whether to unfold all bends in the sheet metal body. When true, all bends are unfolded and the bendFaces property is ignored. When false (default), only the bend faces specified in bendFaces are unfolded. The default value is false.
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():
stationaryFace Gets and sets the stationary face for the unfold. This face remains fixed while the sheet is unfolded. The stationary face is set when createInput is called but can be changed before calling add.
