Introduction

A Part Part2DObject, or formally a Part::Part2DObject, is a simple element with a topological shape that can be displayed in the 3D view.

The Part::Part2DObject is derived from the Part Feature, but is specialized for 2D geometry, given that its shape will lie on a plane. This plane is defined by its DataPlacement property (position, normal, and rotation). However, the plane can also be defined by supporting geometrical elements, such as the plane created by three arbitrary vertices, or a face of a solid body.

Usage

The Part Part2DObject is an internal object, so it cannot be created from the graphical interface, only from the Python console as described in the Scripting section.

The Part::Part2DObject is defined in the Part Workbench but can be used as the base class for scripted objects in all workbenches that produce 2D geometrical shapes. For example, it is the base object for sketches (Sketcher SketchObject), and for most objects created with the Draft Workbench.

Workbenches can add more properties to this basic element to produce an object with complex behavior.

Properties

See Property for all property types that scripted objects can have.

The Part Part2DObject (Part::Part2DObject class) is derived from the Part Feature (Part::Feature class) and inherits all its properties.

The Part Part2DObject also has the following additional properties in the property editor. Hidden properties can be shown by using the Show hidden command in the context menu of the property editor.

See Part Feature for the general information on adding objects to the document.

A Part2DObject is created with the addObject() method of the document. 

import FreeCAD as App

doc = App.newDocument()
obj = App.ActiveDocument.addObject("Part::Part2DObject", "Name")
obj.Label = "Custom label"

For Python subclassing you should create a Part::Part2DObjectPython object. 

import FreeCAD as App

doc = App.newDocument()
obj = App.ActiveDocument.addObject("Part::Part2DObjectPython", "Name")
obj.Label = "Custom label"
