DefeaturingWB-ico.svg 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.

It is also possible to direct modeling the model, when the history of operations is unavailable. (This is the case for 3d STEP models). Defeaturing can also useful to remove proprietary details of the model before sharing it.

Defeaturing-ico.svg 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.



The Defeaturing Tools are located in a separate mask.

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!
