FaceGroup Object Preview

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

Represent a connected region on a single geometric surface.

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().
createForAssemblyContext Returns a proxy for the native object - i.e. a new object that represents this object but adds the assembly context defined by the input occurrence.

Properties

Name Description
area Returns the area in cm ^ 2.
assemblyContext Returns the assembly occurrence (i.e. the occurrence) of this object in an assembly. This is only valid in the case where this face group object is acting as a proxy in an assembly. Returns null in the case where the object is not in the context of an assembly. but is already the native object.
boundingBox Returns the bounding box of this face
centroid Returns a point at the centroid (aka, geometric center) of the face.
entityToken Returns a token for the face group object. This can be saved and used at a later time with the Design.findEntityByToken method to get back the same face.

When using entity tokens it's important to understand that the token string returned for a specific entity can be different over time. However, even if you have two different token strings that were obtained from the same entity, when you use findEntityByToken they will both return the same entity. Because of that you should never compare entity tokens as way to determine what the token represents. Instead, you need to use the findEntityByToken method to get the two entities identified by the tokens and then compare them.

This is only valid for faces that exist in the design, (the isTemporary property is false).
isPlanar Returns if the face group is planar or not.
isValid Indicates if this object is still valid, i.e. hasn't been deleted or some other action done to invalidate the reference.
nativeObject The NativeObject is the object outside the context of an assembly. Returns null in the case where this object is not in the context of an assembly but is already the native object.
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():
parentBody Returns the parent body of the face.
tempId Returns the temporary ID of this face group. This ID is only good while the document remains open and as long as the owning mesh body is not modified in any way.
