GeometricConstraint Object

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

Description

The base class for all geometric constraints.

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 constraint. The IsDeletable property can be used to determine if this constraint can be deleted.

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 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.
attributes Returns the collection of attributes associated with this geometric constraint.
entityToken Returns a token for the GeometricConstraint object. This can be saved and used at a later time with the Design.findEntityByToken method to get back the same geometric constraint.

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.
isDeletable Indicates if this constraint is deletable.
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():
parentSketch Returns the parent sketch object.
