Defeaturing Workbench/it

Introduzione
Defeaturing WB is an add-on workbench intended for editing STEP models, removing of the selected features from the model. It is not part of the standard FreeCAD install.

Permette la rimodellazione anche quando la cronologia delle operazioni non è disponibile. (Questo è il caso dei modelli 3D STEP). La defeaturing può anche essere utile per rimuovere le informazioni proprietarie del modello prima di condividerlo.

Features:

Defeaturing WB: a set of tools to edit a Shape or a STEP model, removing holes, faces, simplifying the model, change the tolerance, apply Fuzzy Boolean operations...

There are also tools to create more solid shapes, from edges, faces or shells.

These defeaturing and repairing tools work with FreeCAD 0.15, 0.16, 0.17 and 0.18. More advance defeaturing tools can be used if OCC7.3 are available.

External workbenches
FreeCAD workbenches are easy to program in Python, there are therefore many people developing additional workbenches outside of the FreeCAD main developers.

The external workbenches page has some information and tutorials on some of them, and the FreeCAD Addons project aims at gathering them and making them easily installable from within FreeCAD.

New workbenches are in development, stay tuned!
