BRepLoop Object

Derived from: Base Object
Defined in namespace "adsk::fusion" and the header file is <Fusion/BRep/BRepLoop.h>

Description

Represents a connected portion of a BRepFace boundary. It consists of a chain of BRepCoEdges.

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
assemblyContext Returns the assembly occurrence (i.e. the occurrence) of this object in an assembly. This is only valid in the case where this BRepLoop 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.
body Returns the parent body of the loop.
boundingBox Returns the bounding box of this loop
coEdges Returns the BRepCoEdges consisting this loop
edges Returns the BRepEdges used by this loop
entityToken Returns a token for the BRepLoop object. This can be saved and used at a later time with the Design.findEntityByToken method to get back the same loop.

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 loops that exist in the design, (the isTemporary property is false).
face Returns the parent face of the loop.
isOuter Returns true of this loop is an outer loop of a face
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():
