Introduction

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.

Features:

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

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.

Tools

The Defeaturing Tools are located in a separate mask.

These are in particular:

Remove Holes: remove Hole from Face
Remove listed Faces: remove 'in List' Faces
Add Faces from 'in List' Edges: add Faces from 'in List' Edges
Select Faces to be Parametric defeatured: select Faces to be Parametric defeatured
Create a copy of the 'in List' Edges : Create a copy of the 'in List' Edges

copy Faces from 'in List' Faces : copy Faces from 'in List' Faces
offset face: offset face
offset edge: offset edge

Make Solid from in List Faces: make Solid from in List Faces
Make Solid from the Faces of the selected Objects: make Solid from the Faces of the selected Objects
Make Solid from in List Faces: select ONE object to try to make a Solid through STEP import/export process
Connect: Connect
clean Face(s) removing holes and merging Outwire: clean Face(s) removing holes and merging Outwire

show 'in List‘ Edge(s): show 'in List‘ Edge(s)
show 'in List‘ Face(s): show 'in List‘ Face(s)
refine: refine
simple copy: simple copy
parametric Refine: parametric Refine

geometry check: geometry check
get Tolerance value: get Tolerance value
set Tolerance value: set Tolerance value

make Edge from selected Vertexes: make Edge from selected Vertexes

Installation

Automatic installation

- automatically using the FreeCAD Add-on Manager (bundled in to 0.17 dev version under Tools Menu)

From GitHub

- manually by copying the Manipulator folder to the Mod sub-directory of the FreeCAD application.

FC Defeaturing WB github page

Supports

FreeCAD v0.15 4671
FreeCAD v0.16 >= 6712
FreeCAD v0.17 >= 13522
FreeCAD v0.18

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!

User documentation
