Feature

Introduction
In FreeCAD the word "Feature" is normally used to refer to a PartDesign Feature object ( class) that is defined by the PartDesign Workbench. This is an operation or modelling step performed to create or modify a solid Shape following the feature editing paradigm.

See PartDesign Feature for more information about this type of object.

Usage

 * 1) Switch to the PartDesign Workbench.
 * 2) Press.
 * 3) Press  to create a new Sketch.
 * 4) Create a closed wire, and then use  to extrude the sketch, and create an initial solid. This initial solid is the initial Feature.
 * 5) Add more sketches and pads, and use other tools of the PartDesign Workbench to modify and transform the initial solid. Each of these steps correspond to Features of the Body.
 * 6) Alternatively, add primitive objects, like  and . Any number of additive and subtractive steps are Features that are used to create a final volume.
