New help system
The help system was rewritten and upgraded to display information directly from our Wiki. The system now relies on the Help Addon. When you first use the Help tool or the What's this? tool you will be asked to install it.
|Der Navigationswürfel wurde überarbeitet, um diese neuen Funktionen zu ermöglichen:
|Tooltips now display the command name in the title, making it easier for new users to look for help. At the end of the tooltip the "internal" command name is added in parentheses: (Std_WhatsThis). This is also the name of the page that documents the command in the Wiki. Forum discussion, Pull request #4978 .|
|The new Std UserEditMode command allows the user to choose an edit mode that will be used when an object is double-clicked in the Tree view. Click the image on the left so see an animation of the selection. If a selected edit mode is not applicable, the object's default edit mode is used instead. Pull request #5110.|
|The Tree view context menu has the new entry Add dependent objects to selection.|
Forum discussion, Pull request #4133.
In the image the Hole001 object was selected and then its
|The new tool Section Cut allows to get non-hollow and also persistent cuts of parts and assemblies.|
Forum discussion, Pull request #4118.

- Es ist nun möglich, die Ansicht des Abhängigkeitsgraphen mit der Maus zu verschieben. Forumsdiskussion, pull request #4638.
- Es wurde ein Problem behoben, bei dem die Verwendung eines Stifttabletts (z.B. Wacom Tablett) so langsam war, dass es völlig unbrauchbar wurde. Forumsdiskussion, pull request #4687.
Kernsystem, Anwendung, Basis und Gui Namensräume
|A new type of add-on called a Preference Pack was added, allowing a subset of a user preferences file (user.cfg) to be saved, distributed, and easily applied by other users. Preference Packs can be use to distribute "Themes," for example, by allowing a developer to include both a Qt stylesheet for widgets as well as a set of other colors and styles for items in the user interface that cannot be set using a stylesheet (e.g. text colors in the Python editor or report view, etc.). Anything that can be configured via a user.cfg file can be set using a Preference Pack. Forum discussion|
|The "Workbenches" preference panel was modified to support the ability to "autoload" workbenches on FreeCAD startup.|
On Linux, the default location of FreeCAD's configuration, data and cache files was changed to follow the XDG Base Directory Specification. Here is a comparison of the old and new locations:

|The Addon Manager was modified to support the distribution of Preference Packs, and to display information found in an addon's metadata. The Addon Manager also includes improved support for Addons whose source code is located at several different git hosting locations. Networking support was improved to provide more robust handling of SSL connections and support for proxies requiring authentication. Support was added for automatically adding macro buttons to the toolbar after installing, for disabling Addons without removing them, and for switching which git branch of an Addon is checked out. Finally, the user interface was modified to improve searching and display of different list filters.|
With the Attach Feature it is now possible to place Windows and Equipment parametrically and intuitively in relation to Walls. To use this feature the experimental external SketchArch Workbench must be installed. Add-on and ReadMe on Github (Not yet available in the Add-on Manager).
|New properties for Arch Structure objects:
A new command Create multiple Arch Structure was also added. It uses the first selected object as a Base, and creates Arch Structures objects for every Edge of the other selected objects. Then, the properties of individual Structure objects can be adjusted in the Property editor. This command was added for workflow with a master Sketch (there is risk of topological naming problem unless you create non-parametric copy of the master Sketch or use Realthunder's version).
Support for 2D data such as linework, hatches, texts and dimensions is now enabled in IFC import and export, which contributes to making the IFC format more and more suitable for traditional 2D CAD work. A similar effort is being made in BlenderBIM. More 2D workflow improvements are documented in this forum thread.
- A Global checkbox was added to the task panel of many drafting commands. Checking it allows input of coordinates in the global coordinate system even if the working plane is not aligned with the global XY plane.
- The Draft Hatch command was introduced. It creates hatches on the faces of a selected object using patterns from AutoCAD PAT files.
- The Draft AddNamedGroup command was introduced. The Draft AddToGroup command was extended with the same functionality.
- Work on the Draft SetStyle command, still in progress in FreeCAD version 0.19, was completed.
- A double-click edit option was added for Draft Texts. It opens the same edit task panel used when creating a text.
- For Draft Dimensions the
archAnsichtUnit Override for imperial architectural dimensions was introduced.
- Draft Shape2DView objects now have an DatenAuto Update property. Setting it to
falsecan be useful if there are many Draft Shape2DViews in a document or if they are complex.
- It is now possible to reverse a Draft Wire via the Draft Edit context menu. Forum discussion, Pull request #4811.
Weitere Entwurf Verbesserungen
- Behoben Entwurf Fang Gitter, wenn sich der Mauszeiger über einer Fläche befindet. Forumsdiskussion. Git commit.
- Support for two DWG converters was added: LibreDWG and QCAD pro. See Import Export Preferences and FreeCAD and DWG Import for more information.
||Es gibt eine neue Eigenschaft für den Gmsh Vernetzer. Die Anzahl der Netzelemente pro mal dem Radius der Krümmung kann angegeben werden. Der Standardwert ist 12. Um ein feineres Netz an kleinen Ecken oder Löchern zu erhalten, kann dieser Wert erhöht werden, um bessere Ergebnisse zu erzielen. Diese Funktion erfordert Gmsh 4.8 oder eine neuere Version.|
||FreeCAD erlaubt nun die Auswahl eines Algorithmus sowie die 3D Netzrekombination für den Gmsh Vernetzers. Für weitere Details über die Rekombination von Netzelementen siehe FEM NetzGmshAusForm.|
Weitere FEM Verbesserungen
- Important: Starting from this release, FreeCAD will use SI units (m, kg, s, K, A, mol, cd) to write the Elmer solver input files (case.sif and mesh.nodes). This is independent of the used FreeCAD unit system.
- Important: Starting from this release, the scale of result pipelines and their filters will use SI units (m, kg, s, K, A, mol, cd). So the displacement is given in meter, the stress in Pascal. This applies to all SI-derived FreeCAD unit systems.
- Solving with the Calculix solver now uses all CPU cores. Pull request #6374
- Meshing with Gmsh now uses all CPU cores. Pull request #6370
- The element order of Gmsh meshes can be changed via the mesh dialog. Pull request #4660
- The Data at point clip result filter is now actually working: One gets info from result meshes by clicking into them or by specifying a mesh coordinate.
- A new constraint was added: Model → Mechanical Constraints → Constraint Centrif. Pull request #4738
- A new solver was added: Solve → Solver Mystran. Multiple commits.
- A new constraint was added: Model → Mechanical Constraints → Constraint Spring. Pull request #4982
- It is now possible to have result pipelines with several filters, where some take other filters as input, and some take the results directly from the pipeline. commit 708a300b
- Material cards can now contain values for the electrical conductivity. Pull request #4647
- Material cards added for Nitrogen and Argon. Pull request #4649
- Support for the Gmsh mesh algorithms "HXT" (3D) and "Packing Parallelograms" (2D) added. Pull request #4654
- Allow to specify an algorithm for the Gmsh property "High Order Optimize". Pull request #4705
- Nonlinear solid materials with simple hardening can now have an arbitrary number of yield points. Pull request #5024
- Allow modal adding/removal of geometric entities to constraints acting on boundaries. Pull request #5117
- Most FEM constraint dialogs now behave uniformly and provide the same 3D object selection features. Pull request #5391
- DXF: The missing unit block was added to the header14.rub file. Pull request #5793
Improved support for NASTRAN GRID elements
The Mesh import tool now supports the high-precision "GRID*" element. The standard-precision "GRID" element was also improved, now supporting both space-delimited numeric input as well as fixed-field-width input, per the NASTRAN95 format documentation.
Weitere Polygonnetz Verbesserungen
Fixed false negatives during self-intersection tests when facets are coplanar: Pull request #5002.
Interoperability with OpenSCAD has been improved, adding support for several operations missing from earlier versions (linear extrude with rotations, rotational extrusions). Several operations are modified to provide improved FreeCAD object equivalents, particularly for twisted extrusions. Surface generation from discrete data was modified to give more OpenSCAD-like results, rather than splined surfaces.
New options were added to support running either FreeCAD, OpenSCAD, or both, in sandboxed environments such as AppImages and Snap packages: data can now be transferred to and from OpenSCAD via the standard temporary directory mechanism, via a user-specified temp directory that both executables have access to, or new to OpenSCAD 2021.1, via a "stdout pipe" mechanism, bypassing temporary files entirely.
|The following options were added to the task panel of the Add OpenSCAD element feature:
Load - load a scad file Save - save a scad file Refresh - Update FreeCAD view Clear - Clear text input
A new text box gives feedback about OpenSCAD errors.
Tapered extrusion of a sketch with an inner structure.
|A tapered extrusion of inner structures now creates usable results. Previously, inner structures were extruded as if they were stand-alone and not part of a structure.|
Weitere Formteil Verbesserungen
- The dialog to edit Cylinders now allows to specify an angle relative to the normal of the chosen attachment plane. This way one can create skew cylinders. Pull request #4708
- The Face Colors tool now also allows to set the transparency (Alpha channel) of faces. This transparency can be exported, making e.g. STEP files with transparent parts possible.
- The following commands now support App::Links: Loft, Sweep, Extrude, Revolve, Reverse shapes, Mirror, Offset2D, Offset3D, Check Geometry, Ruled Surface, Cross-sections, and Thickness. Pull request #6478
Padding along an edge from the model.
Click on the image to see the animation.
|There is a new option to Pad along the direction of an edge in the 3D model.|
|When Distance and Angle is specified in the Chamfer tool and faces are selected, the distance will be applied along the selected faces. Likewise if two distances are specified then Size 1 will be applied along the selected face.|
A loft with multiple sections, the final one is a vertex.
|It is now possible to create an Additive or Subtractive Loft, or an Additive or Subtractive Pipe towards, or from, a Vertex of either a sketch or a body. This allows to create pyramids for example.|
Note: Vertices in sketches are created as construction geometry. To use them as endpoints of lofts, you must first change them to normal geometry.
A tapered pocket within a non-tapered pad.
|The dialog for Pad and Pocket offers to set a taper angle for the extrusion.|
Pocketing along different directions.
Click on the image to see the animation.
|It is now possible to specify the direction for the Pocket extrusion.|
|The dialog to edit Cylinders (additive and subtractive) now allows to specify an angle relative to the normal of the chosen attachment plane. This way one can create skew cylinders. Pull request #4708|
|The Helix feature has the new mode Height-Turns-Growth to create flat spirals.|
A single Pad and a single Revolution with nested profiles. The base block is only there to ensure that the part is a single solid.
|All PartDesign features that can extrude sketches can now handle sketches with nested profiles that form islands. For example it is possible to Revolve a sketch consisting of 3 nested circles with the same center point.|
Note: Extruding nested profiles only works if the result is still a single body.
Effect of the new option Length along sketch normal.
Click on the image to see the animation.
|There is a new option to Pad a certain length along the direction. The length is either measured along the sketch normal or along the custom direction.|
|The Hole feature can now model true threads.|
Weitere PartDesign Verbesserungen
- In the Helix feature one can now also use the sketch normal as axis. Pull request #5199
- The Sprocket feature can now also create ISO-normed sprockets. Forum thread Pull request #4478
- The Loft and Pipe features now allow using the body's faces for sections. Pull request #5155
- It is now possible to select several faces before calling the Pad or Pocket dialog. In this case the first selected face will be used to determine the default padding/pocketing direction. commit d34a5616
- It is possible to offset SubShapeBinders if they are based on edges, wires or faces. Pull request #6338
- SubShapeBinders now have the Refine property like all other PartDesign objects. Pull request #6550
- In the Chamfer and Fillet dialogs all edges of a body can be selected via the context menu while in Add mode. Pull request #5269
When you selected a 3D object before clicking the icon to create a fillet or chamfer, all object edges will automatically be selected. Pull request #5328
- Chamfer and Fillet dialogs now each have a new Use all edges checkbox, which is connected to the Use All Edges property for these objects. When the box is checked the property is set to True, when unchecked the property is set to False. When Use All Edges is True there is protection against the topological naming problem because then all of the edges of the base object are used regardless of how many edges there are. Pull request #5340
- Plane selection when adding a new sketch can now be achieved with a single-click in the 3D View. Pull request Forum discussion
- When a PartDesign tool is run without an active body, FreeCAD now offers to activate a body or create a new one. Pull request #4949

- The new %w format specifier is now the default. And the format specifier preference was moved from the Advanced tab to the Dimension tab. Pull request #6504.
- Flipped diagonal hatch was added for the Geometric Hatch tool. Pull request #6429.
- There is a new option to show a grid in a page. Several related preferences have been introduced. Pull request #6465.
- The unit display in dimensions was fixed according to standards. The degree symbol is always present for the dimension value and tolerances, other units only appear if ShowUnits is set. The unit appears immediately after the dimension value unless there is a tolerance, then it appears after the tolerance. Pull request #6581
Qt WebEngine is now considered the default option instead of Qt WebKit.
Note: these are the new workbenches created in this development cycle, or older workbenches that received updates. See external workbenches for more workbenches that can be installed, and which cover a wide variety of topics. If you want to see your workbench added, join the forum and present your code.
Several features to view, inspect and edit existing constraints were added. One can now e.g. highlight constraints with a label, suppress a constraint temporarily or run the solver only for a particular constraint.
For more information see the constraint handling description.
|The Assembly3 Workbench is available (as of March 2022) through the AddonManager. This makes for easy installation and management of the external dependencies of the workbench.
Assembly3 is used to create assemblies of different bodies contained in a single file or in multiple documents leveraging the full power of FreeCAD’s Link system. Learn more about Links in this video presentation from Realthunder.
Assembly3 Workbench uses SolveSpace as it’s solver.
Different length of a beam as variant.
|New feature to add variants. These are links to a part with varying parameters, meaning that you can insert the same part several times, and adjust the parameters of each instance. For more info see this forum thread.|
An animated assembly.
Click on the image to see the animation.
|Animations can be exported to the MP4 and GIF format.|
The FCGear Workbench received a couple of improvements:
- For involute gears, the outside (aka tip) and root diameter are exposed as properties (details).
- Gear objects are now attachable (details).
- Gear objects can now be used as additive features in PartDesign Bodies (details).
- The creation of gear objects now appears in the undo stack (details).
- The Plot module has been stripped from the Plot Workbench since it is now provided by FreeCAD.
The Ship Workbench is back to life!

Since this release FreeCAD can only be compiled using Qt 5.x and Python 3.x. The lowest supported Python version is 3.6.9 according to this forum thread.
Um FreeCAD unter Windows kompilieren, gibt es verschiedene Libpacks (vorgepackte Bibliotheken):
- Libpack für Windows mit Qt xx, OCC yy, und Python zz
The supported operating systems are:
- Windows 7, 8, 10 and 11
- Linux Ubuntu Bionic Beaver (18.04) and Focal Fossa (20.04)
- MacOS: 10.12 Sierra or newer
Since FreeCAD 0.19 we no longer officially support 32bit Windows. FreeCAD might work on these systems, but no support is given.
Remote Desktop under Windows
Depending on the OpenGL graphics capabilities of a computer, it might be that one encounters a crash when running FreeCAD via remote desktop. To fix this upgrade your OpenGL driver. Only if this doesn't help:
- Download this OpenGL library for 64bit Windows and extract it.
- Rename the DLL file to opengl32sw.dll and copy it to the bin subfolder of FreeCAD's installation folder (overwrite the existing DLL there).
