In FreeCAD the word "Feature" is normally used to refer to a PartDesign Feature object (
PartDesign::Feature 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.
- Switch to the PartDesign Workbench.
- Press PartDesign Body.
- Press PartDesign NewSketch to create a new Sketch.
- Create a closed wire, and then use PartDesign Pad to extrude the sketch, and create an initial solid. This initial solid is the initial Feature.
- 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.
- Alternatively, add primitive objects, like PartDesign Additive box and PartDesign Subtractive cylinder. Any number of additive and subtractive steps are Features that are used to create a final volume.
In the general sense, a "Feature" can be any modelling step used to create a final Shape, with any tool of any workbench.
In a more specific sense, a "Feature" is a modelling step used inside a PartDesign Body.
