Layer Object Preview

Derived from: EcadObject Object
Defined in namespace "adsk::electron" and the header file is <Electron/Layers/Layer.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

Layer in a board, schematic, or library.

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
color Layer color as ARGB hex string (e.g., ``0xc8ff0000``).
fill Fill pattern used in layer icon.
id Identifier of the object.
isValid Indicates if this object is still valid, i.e. hasn't been deleted or some other action done to invalidate the reference.
name Display name of this layer (e.g., Top, Bottom, tPlace).
number Layer number (1-based index into the layer stack).
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():
used True if this layer contains objects; False if empty.
visible True if this layer is visible in the editor; False if hidden.
